Changbom Park studies the cosmic microwave background radiation, large-scale structure of the universe, and galaxies to understand the nature of the universe and the galaxy formation process. He constrains cosmological models and galaxy formation theories by comparing the results of cosmological simulations with observations. He works on topology of large-scale structure, and was one of the first to measure the power spectrum of galaxy distribution.

TITLE | The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the Extended Baryon Oscillation Spectroscopic Survey and from the Second Phase of the Apache Point Observatory Galactic Evolution Experiment |
ARCHIVE | |
FILE | |
JOURNAL | ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES, 235(2), 42, 2018 |
ABSTRACT | The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as The Cannon; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

TITLE | Supercluster A2142 and collapse in action: infalling and merging groups and galaxy transformations |
ARCHIVE | |
FILE | |
JOURNAL | ASTRONOMY & ASTROPHYSICS, 620, A149, 2018 |
ABSTRACT | Context. Superclusters with collapsing cores represent dynamically evolving environments for galaxies, galaxy groups, and clusters. Aims. We study the dynamical state and properties of galaxies and groups in the supercluster SC1 A2142 that has a collapsing core, to understand its possible formation and evolution. Methods. We find the substructure of galaxy groups using normal mixture modelling. We have used the projected phase space (PPS) diagram, spherical collapse model, clustercentric distances, and magnitude gap between the brightest galaxies in groups to study the dynamical state of groups and to analyse group and galaxy properties. We compared the alignments of groups and their brightest galaxies with the supercluster axis. Results. The supercluster core has a radius of about 8 h(-1) Mpc and total mass M-tot approximate to 2.3 x 10(15) h(-1) M-circle dot and is collapsing. Galaxies in groups on the supercluster axis have older stellar populations than off-axis groups, with median stellar ages 4-6 and <4 Gyr, correspondingly. The cluster A2142 and the group Gr8 both host galaxies with the oldest stellar populations among groups in SC1 A2142 having the median stellar age t > 8 Gyr. Recently quenched galaxies and active galactic nuclei (AGNs) are mostly located at virial radii or in merging regions of groups, and at clustercentric distances D-c approximate to 6 h(-1) Mpc. The most elongated groups lie along the supercluster axis and are aligned with it. Magnitude gaps between the brightest galaxies of groups are less than one magnitude, suggesting that groups in SC1 A2142 are dynamically young. Conclusions. The collapsing core of the supercluster, infall of galaxies and groups, and possible merging groups, which affect galaxy properties and may trigger the activity of AGNs, show how the whole supercluster is evolving.

TITLE | Resolution convergence in cosmological hydrodynamical simulations using adaptive mesh refinement |
ARCHIVE | |
FILE | |
JOURNAL | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 477(1), 983-1003, 2018 |
ABSTRACT | We have explored the evolution of gas distributions from cosmological simulations carried out using the RAMSES adaptive mesh refinement (AMR) code, to explore the effects of resolution on cosmological hydrodynamical simulations. It is vital to understand the effect of both the resolution of initial conditions (ICs) and the final resolution of the simulation. Lower initial resolution simulations tend to produce smaller numbers of low-mass structures. This will strongly affect the assembly history of objects, and has the same effect of simulating different cosmologies. The resolution of ICs is an important factor in simulations, even with a fixed maximum spatial resolution. The power spectrum of gas in simulations using AMR diverges strongly from the fixed grid approach with more power on small scales in the AMR simulations even at fixed physical resolution and also produces offsets in the star formation at specific epochs. This is because before certain times the upper grid levels are held back to maintain approximately fixed physical resolution, and to mimic the natural evolution of dark matter only simulations. Although the impact of hold-back falls with increasing spatial and IC resolutions, the offsets in the star formation remain down to a spatial resolution of 1 kpc. These offsets are of the order of 10-20 per cent, which is below the uncertainty in the implemented physics but are expected to affect the detailed properties of galaxies. We have implemented a new grid-hold-back approach to minimize the impact of hold-back on the star formation rate.

TITLE | Noise characterization of IUCAA digital sampling array controller |
ARCHIVE | |
FILE | |
JOURNAL | JOURNAL OF ASTRONOMICAL TELESCOPES INSTRUMENTS AND SYSTEMS, 4(3), 36002, 2018 |
ABSTRACT | The IUCAA digital sampling array controller (IDSAC) is a flexible and generic yet powerful CCD controller that can handle a wide range of scientific detectors. Based on an easily scalable modular backplane architecture consisting of single board controllers (SBC), IDSAC can control large detector arrays and mosaics. Each of the SBCs offers the full functionality required to control a CCD independently. The SBCs can be cold swapped without the need to reconfigure them. IDSAC is also available in a backplane-less architecture. Each SBC can handle data from up to four video channels with or without dummy outputs at speeds up to 500-kilo pixels per second (kPPS) per channel with a resolution of 16 bits. Communication with a Linux-based host computer is through a USB3.0 interface, with the option of using copper or optical fibers. A field programmable gate array (FPGA) is used as the master controller in each SBC, which allows great flexibility in optimizing performance by adjusting gain, timing signals, bias levels, etc., using user-editable configuration files without altering the circuit topology. Elimination of thermal kTC noise is achieved via digital correlated double sampling (DCDS). The number of digital samples per pixel (for both reset and signal levels) is user configurable. We present the results of noise performance characterization of IDSAC through simulation, theoretical modeling, and actual measurements. The contribution of different types of noise sources is modeled using a tool to predict noise of a generic DCDS signal chain analytically. The analytical model predicts the net input referenced noise of the signal chain to be 5 electrons for 200-k pixels/s per channel readout rate with three samples per pixel. Using a cryogenic test setup in the lab, the noise is measured to be 5.4 e (24.3 mu V), for the same readout configuration. With a better-optimized configuration of 500-kPPS readout rate, the measured noise is down to 3.8 electrons RMS (17 mu V), with three samples per interval.

TITLE | Minkowski Tensors in Two Dimensions: Probing the Morphology and Isotropy of the Matter and Galaxy Density Fields |
ARCHIVE | |
FILE | |
JOURNAL | ASTROPHYSICAL JOURNAL, 858(2), 87, 2018 |
ABSTRACT | We apply the Minkowski tensor statistics to two-dimensional slices of the three-dimensional matter density field. The Minkowski tensors are a set of functions that are sensitive to directionally dependent signals in the data and, furthermore, can be used to quantify the mean shape of density fields. We begin by reviewing the definition of Minkowski tensors and introducing a method of calculating them from a discretely sampled field. Focusing on the statistic W-2(1,1)-a 2 x 2 matrix-we calculate its value for both the entire excursion set and individual connected regions and holes within the set. To study the morphology of structures within the excursion set, we calculate the eigenvalues lambda(1), lambda(2) for the matrix W-2(1,1) of each distinct connected region and hole and measure their mean shape using the ratio beta equivalent to . We compare both W-2(1,1) and beta for a Gaussian field and a smoothed density field generated from the latest Horizon Run 4 cosmological simulation to study the effect of gravitational collapse on these functions. The global statistic W-2(1,1) is essentially independent of gravitational collapse, as the process maintains statistical isotropy. However, beta is modified significantly, with overdensities becoming relatively more circular compared to underdensities at low redshifts. When applying the statistics to a redshift-space distorted density field, the matrix W-2(1,1) is no longer proportional to the identity matrix, and measurements of its diagonal elements can be used to probe the large-scale velocity field.

TITLE | Minkowski Tensors in Three Dimensions: Probing the Anisotropy Generated by Redshift Space Distortion |
ARCHIVE | |
FILE | |
JOURNAL | ASTROPHYSICAL JOURNAL, 863(2), 200, 2018 |
ABSTRACT | We apply the Minkowski tensor statistics to three-dimensional Gaussian random fields. Minkowski tensors contain information regarding the orientation and shape of excursion sets that is not present in the scalar Minkowski functionals. They can be used to quantify globally preferred directions and also provide information on the mean shape of the subsets of a field. This makes them ideal statistics to measure the anisotropic signal generated by redshift space distortion in the low-redshift matter density field. We review the definition of the Minkowski tensor statistics in three dimensions, focusing on two coordinate invariant quantities, W-1(0,2) and W-2(0,2). We calculate the ensemble average of these 3 x 3 matrices for an isotropic Gaussian random field, finding that they are proportional to products of the identity matrix and a corresponding scalar Minkowski functional. We show how to numerically reconstruct W-1(0,2) and W-2(0,2) from discretely sampled fields and apply our algorithm to isotropic Gaussian fields generated from a linear Lambda CDM matter power spectrum. We then introduce anisotropy by applying a linear redshift space distortion operator to the matter density field and find that both W-1(0,2) and W-2(0,2) exhibit a distinct signal characterized by inequality between their diagonal components. We discuss the physical origin of this signal and how it can be used to constrain the redshift space distortion parameter gamma = f/b.

TITLE | JINGLE, a JCMT legacy survey of dust and gas for galaxy evolution studies - I. Survey overview and first results |
ARCHIVE | |
FILE | |
JOURNAL | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 481(3), 3497-3519, 2018 |
ABSTRACT | JINGLE is a new JCMT legacy survey designed to systematically study the cold interstellar medium of galaxies in the local Universe. As part of the survey we perform 850 mu m continuum measurements with SCUBA-2 for a representative sample of 193 Herschel-selected galaxies withM(*) > 10(9) M-circle dot, as well as integrated CO(2-1) line fluxes with RxA3m for a subset of 90 of these galaxies. The sample is selected from fields covered by the Herschel-ATLAS survey that are also targeted by the MaNGA optical integral-field spectroscopic survey. The new JCMT observations combined with the multiwavelength ancillary data will allow for the robust characterization of the properties of dust in the nearby Universe, and the benchmarking of scaling relations between dust, gas, and global galaxy properties. In this paper we give an overview of the survey objectives and details about the sample selection and JCMT observations, present a consistent 30-band UV-to-FIR photometric catalogue with derived properties, and introduce the JINGLE Main Data Release. Science highlights include the non-linearity of the relation between 850 mu m luminosity and CO line luminosity (log LCO(2-1) = 1.372 logL(850)-1.376), and the serendipitous discovery of candidate z > 6 galaxies.

ARCHIVE | |

JOURNAL | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 472(2), 2772-2785, 2018 |
ABSTRACT | Large deviation statistics is implemented to predict the statistics of cosmic densities in cylinders applicable to photometric surveys. It yields few per cent accurate analytical predictions for the one-point probability distribution function (PDF) of densities in concentric or compensated cylinders; and also captures the density dependence of their angular clustering (cylinder bias). All predictions are found to be in excellent agreement with the cosmological simulation Horizon Run 4 in the quasi-linear regime where standard perturbation theory normally breaks down. These results are combined with a simple local bias model that relates dark matter and tracer densities in cylinders and validated on simulated halo catalogues. This formalism can be used to probe cosmology with existing and upcoming photometric surveys like DES, Euclid or WFIRST containing billions of galaxies.

ARCHIVE | |
FILE | |
JOURNAL | ASTROPHYSICAL JOURNAL, 869(2), 124, 2018 |
ABSTRACT | We study the rotational motion of the galaxy cluster A2107 at redshift z = 0.04 and its connection to nearby largescale structures using a large amount of spectroscopic redshift data. By combining 978 new redshifts from the MMT/Hectospec observations with data in the literature, we construct a large sample of 1968 galaxies with measured redshifts at clustercentric radius R < 60. Our sample has high (80%) and spatially uniform completeness at r -band apparent magnitude mr,(Petro,0) < 19.1. We first apply the caustic method to the sample and identify 285 member galaxies of A2107 at R < 60. Then the rotation amplitude and the position angle of the rotation axis are measured. We find that the member galaxies show strong global rotation at R < 20 (v(rot)/ sigma(v) similar to 0.6) with a significance of >3.8 sigma, which is confirmed by two independent methods. The rotation becomes weaker in outer regions. There are at least five filamentary structures that are connected to the cluster and that consist of known galaxy groups. These structures are smoothly connected to the cluster, which seem to be inducing the global rotation of the cluster through inflow of galaxies.

JOURNAL | JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS, no.10, 11, 2018 |
ABSTRACT | We employ the rank-2 contour Minkowski tensor in two dimensions to probe length and time scales of ionized bubbles during the epoch of reionization. We demonstrate that ionized bubbles are not circular, and hence not spherical in three dimensions, as is often assumed for simplified analytic arguments. We quantify their shape anisotropy by using the ratio of the two eigenvalues of the contour Minkowski tensor. Further, we show that a size parameter constructed from the eigenvalues of this tensor provide an upper bound on the characteristic sizes of ionized bubbles at different redshifts. The shape and size parameters provide information of the characteristic time epochs when bubble mergers begin and end. Our method is expected to be useful to reconstruct the reionization history using data of the brightness temperature field.
