What determines the sizes of red early-type galaxies?

Joon Hyeop Lee, Minjin Kim, Chang Hee Ree +7

The sizes of galaxies are known to be closely related with their masses, luminosities, redshifts and morphologies. However, when we fix these quantities and morphology, we still fi…

The rise and fall of the star formation histories of blue galaxies at redshifts 0.2<z<1.4

Camilla Pacifici, Susan A. Kassin, Benjamin Weiner +2

Popular cosmological scenarios predict that galaxies form hierarchically from the merger of many progenitors, each with their own unique star formation history (SFH). We use a soph…

The North Ecliptic Pole Wide survey of AKARI: a near- and mid-infrared source catalog

Seong Jin Kim, Hyung Mok Lee, Hideo Matsuhara +19

We present a photometric catalog of infrared (IR) sources based on the North Ecliptic PoleWide field (NEP-Wide) survey of AKARI, which is an infrared space telescope launched by Ja…

Post-merger Signatures of Red-sequence Galaxies in Rich Abell Clusters at

Yun-Kyeong Sheen, Sukyoung K. Yi, Chang H. Ree +1

We have investigated the post-merger signatures of red-sequence galaxies in rich Abell clusters at 0.1: A119, A2670, A3330 and A389. Deep images in u', g', r' and medi…

Near-infrared properties of asymptotic giant branch stars in nearby dwarf elliptical Galaxy NGC 205

M. Y. Jung, Jongwan Ko, Jae-Woo Kim +3

We investigated the distribution of resolved asymptotic giant branch (AGB) stars over a much larger area than covered by previous near-infrared studies in the nearby dwarf elliptic…

The parsec-scale jet of PKS 1749+096

R. -S. Lu, Z. -Q. Shen, T. P. Krichbaum +3

PKS 1749+096 is a BL Lac object showing weak extended jet emission to the northeast of the compact VLBI core on parsec scales. We aim at better understanding the jet kinematics and…

The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad Line Region in Mrk 50

Anna Pancoast, Brendon J. Brewer, Tommaso Treu +33

We present dynamical modeling of the broad line region (BLR) in the Seyfert 1 galaxy Mrk 50 using reverberation mapping data taken as part of the Lick AGN Monitoring Project (LAMP)…

Evolution of the baryon fraction in the Local Group: accretion versus feedback at low and high z

Sébastien Peirani, Intae Jung, Joe Silk +1

Using hydrodynamical zoom simulations in the standard LCDM cosmology, we investigate the evolution of the distribution of baryons (gas and stars) in a local group-type universe. Fi…

A Keck/LRIS Spatially-Resolved Spectroscopic Study of a LINER Galaxy SDSS J091628.05+420818.7

Hyun-Jin Bae, Jong-Hak Woo, Masafumi Yagi +2

Using spatially-resolved spectra obtained with the Low Resolution Imaging Spectrometer at the Keck I telescope, we investigate the nature of ionizing sources and kinematic properti…

The SAURON project-XXI. The spatially-resolved UV-line strength relations of early-type galaxies

Hyunjin Jeong, Sukyoung K. Yi, Martin Bureau +13

The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint is the correlation b…

Globular Cluster Systems of Early-type Galaxies in Low-density Environments

J. Cho, R. M. Sharples, J. P. Blakeslee +4

Deep images of 10 early-type galaxies in low-density environments have been obtained with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. The global properties…

The influence of the cluster environment on the star formation efficiency of 12 Virgo spiral galaxies

B. Vollmer, . O. I. Wong, J. Braine +2

The influence of the environment on gas surface density and star formation efficiency of cluster spiral galaxies is investigated. We extend previous work on radial profiles by a pi…

The Hi Environment of Counter-rotating Gas Hosts: Gas Accretion from Cold Gas Blobs

Aeree Chung, Martin Bureau, J. H. van Gorkom +1

We probe the HI properties and the gas environments of three early-type barred galaxies harbouring counter-rotating ionized gas, NGC 128, NGC 3203 and NGC 7332. Each system has one…

Optical and IR Photometry of Globular Clusters in NGC1399: Evidence for Color-Metallicity Nonlinearity

John P. Blakeslee, Hyejeon Cho, Eric W. Peng +3

We combine new Wide Field Camera~3 IR Channel (WFC3/IR) F160W (H) imaging data for NGC1399, the central galaxy in the Fornax cluster, with archival F475W (g), F606W (V), F814W (I),…
