Galaxy evolution in the mid-infrared green valley: a case of the A2199 supercluster
Gwang-Ho Lee, Ho Seong Hwang, Myung Gyoon Lee +4
We study the mid-infrared (MIR) properties of the galaxies in the A2199 supercluster at z = 0.03 to understand the star formation activity of galaxy groups and clusters in the supe…
The double galaxy cluster Abell 2465 - II. Star formation in the cluster
Gary A. Wegner, Devin S. Chu, Ho Seong Hwang
We investigate the star formation rate and its location in the major merger cluster Abell 2465 at = 0.245. Optical properties of the cluster are described in Paper I. Measureme…
Tracing Recent Star Formation of Red Early-type Galaxies out to 1
Jongwan Ko, Ho Seong Hwang, Myungshin Im +3
We study the mid-infrared (IR) excess emission of early-type galaxies (ETGs) on the red-sequence at 1 using a spectroscopic sample of galaxies in the fields of Great Observat…
GOODS-HERSCHEL: star formation, dust attenuation and the FIR-radio correlation on the Main Sequence of star-forming galaxies up to z~4
Maurilio Pannella, David Elbaz, Emanuele Daddi +25
We use deep panchromatic datasets in the GOODS-N field, from GALEX to the deepest Herschel far-infrared and VLA radio continuum imaging, to explore, using mass-complete samples, th…
SHELS: A Complete Galaxy Redshift Survey with R20.6
Margaret J. Geller, Ho Seong Hwang, Daniel G. Fabricant +3
The SHELS (Smithsonian Hectospec Lensing Survey) is a complete redshift survey covering two well-separated fields (F1 and F2) of the Deep Lens Survey to a limiting R = 20.6. Here w…
The Number Density of Quiescent Compact Galaxies at Intermediate Redshift
Ivana Damjanov, Ho Seong Hwang, Margaret J. Geller +1
Massive compact systems at 0.2<z<0.6 are the missing link between the predominantly compact population of massive quiescent galaxies at high redshift and their analogs and relics i…
The Universal Relation of Galactic Chemical Evolution: The Origin of the Mass-Metallicity Relation
Jabran Zahid, Gabriel Dima, Rolf Kudritzki +5
We examine the mass-metallicity relation for . The mass-metallicity relation follows a steep slope with a turnover or `knee' at stellar masses around $10^{10} M_\odo…
