Constructing a Mock Galaxy Catalog for the All-sky SPECtroscopic Survey of Nearby Galaxies (A-SPEC) Using the Machine-assisted Semi-Simulation Model

Dongkok Kim, Yongseok Jo, Ho Seong Hwang +26

We present a methodology for constructing a mock galaxy catalog for the All-sky SPECtroscopic survey of nearby galaxies (A-SPEC) using the Machine-assisted Semi-Simulation Model. T…

The Most Massive Early-type Galaxies Exhibit Tidal Features More Frequently in Lower-density Environments

Yongmin Yoon, Jae-Woo Kim, Jongwan Ko

The most massive early-type galaxies (ETGs) are known to form through numerous galaxy mergers. Thus, it is intriguing to study whether their formation in low-density environments,…

Low-mass Quiescent Galaxies Are Small in Isolated Environments: Environmental Dependence of the Mass-Size Relation of Low-mass Quiescent Galaxies

Yongmin Yoon, Jae-Woo Kim, Jongwan Ko

We study the mass-size relation of quiescent galaxies across various environments, with a particular focus on its environmental dependence at the low-mass part of $\log(M_\mathrm{s…

The Infrared Medium-deep Survey. \Romannum{7}. Faint Quasars at in the ELAIS-N1 Field

Suhyun Shin, Myungshin Im, Yongjung Kim +26

The intergalactic medium (IGM) at 5 to 6 is largely ionized, and yet the main source for the IGM ionization in the early universe is uncertain. Of the possible contributors…
