hCOSMOS: a dense spectroscopic survey of galaxies in the COSMOS field
Ivana Damjanov, H. Jabran Zahid, Margaret J. Geller +2
We describe the hCOSMOS redshift survey of the COSMOS field conducted with the Hectospec spectrograph on the MMT. In the central 1~deg, the hCOS20.6 subset of the survey is $>9…
Demise of Faint Satellites around Isolated Early-type Galaxies
Changbom Park, Ho Seong Hwang, Hyunbae Park +1
The hierarchical galaxy formation scenario in the Cold Dark Matter cosmogony with a non-vanishing cosmological constant and geometrically flat space has been very successful in exp…
Galaxy evolution in the metric of the Cosmic Web
K. Kraljic, S. Arnouts, C. Pichon +19
The role of the cosmic web in shaping galaxy properties is investigated in the GAMA spectroscopic survey in the redshift range . The stellar mass, du…
Galaxy evolution in merging clusters: The passive core of the "Train Wreck" cluster of galaxies, A520
Boris Deshev, Alexis Finoguenov, Miguel Verdugo +9
The mergers of galaxy clusters are the most energetic events in the universe after the Big Bang. With the increased availability of multi-object spectroscopy and X-ray data an ever…
Star formation activity of barred spiral galaxies
Eunbin Kim, Ho Seong Hwang, Haeun Chung +4
We study the star formation activity of nearby galaxies with bars using a sample of late-type galaxies at 0.02 0.05489 and from the Sloan Digital Sky Surv…
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
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
A Redshift Survey of the Nearby Galaxy Cluster Abell 2199: Comparison of the Spatial and Kinematic Distributions of Galaxies with the Intracluster Medium
Hyunmi Song, Ho Seong Hwang, Changbom Park +1
We present the results from an extensive spectroscopic survey of the central region of the nearby galaxy cluster Abell 2199 at . By combining 775 new redshifts from the MMT…
An imperfectly passive nature: Bright sub-millimeter emission from dust-obscured star formation in the z=3.717 "passive" system, ZF20115
J. M. Simpson, Ian Smail, Wei-Hao Wang +28
The identification of high-redshift massive galaxies with old stellar populations may pose challenges to some models of galaxy formation. However, to securely classify a galaxy as…
The dependence of cluster galaxy properties on the central entropy of their host cluster
Jae-Woo Kim, Jongwan Ko, Ho Seong Hwang +4
We present a study of the connection between brightest cluster galaxies (BCGs) and their host galaxy clusters. Using galaxy clusters at from the Hectospec Cluster Surve…
COSMOS2015 photometric redshifts probe the impact of filaments on galaxy properties
Clotilde Laigle, Christophe Pichon, Stephane Arnouts +12
The variations of galaxy stellar masses and colour-types with the distance to projected cosmic filaments are quantified using the precise photometric redshifts of the COSMOS2015 ca…
The Dependence of the Mass-Metallicity Relation on Large Scale Environment
Po-Feng Wu, H. Jabran Zahid, Ho Seong Hwang +1
We examine the relation between gas-phase oxygen abundance and stellar mass---the MZ relation---as a function of the large scale galaxy environment parameterized by the local densi…
The Fastest Galaxy Evolution in an Unbiased Compact Group Sample with WISE
Gwang-Ho Lee, Ho Seong Hwang, Jubee Sohn +1
We study the mid-infrared (MIR) properties of galaxies in compact groups and their environmental dependence using the \textit{Wide-field Infrared Survey Explorer (WISE)} data. We u…
