Ultraviolet color-color relation of early-type galaxies at 0.05 < z < 0.12

Chang H. Ree, Hyunjin Jeong, Kyuseok Oh +4

We present the ultraviolet (UV) color-color relation of early-type galaxies (ETGs) in the nearby universe (0.05 < z < 0.12) to investigate the properties of hot stellar populations…

AKARI Observation of the North Ecliptic Pole (NEP) Supercluster at z = 0.087: mid-infrared view of transition galaxies

Jongwan Ko, Myungshin Im, Hyung Mok Lee +12

We present the mid-infrared (MIR) properties of galaxies within a supercluster in the North Ecliptic Pole region at z?0.087 observed with the AKARI satellite. We use data from the…

Ram pressure stripping of the multiphase ISM and star formation in the Virgo spiral galaxy NGC 4330

B. Vollmer, M. Soida, J. Braine +6

It has been shown that the Virgo spiral galaxy NGC 4330 shows signs of ongoing ram pressure stripping in multiple wavelengths: at the leading edge of the interaction, the Halpha an…

A Refined QSO Selection Method Using Diagnostics Tests: 663 QSO Candidates in the LMC

Dae-Won Kim, Pavlos Protopapas, Markos Trichas +4

We present 663 QSO candidates in the Large Magellanic Cloud (LMC) selected using multiple diagnostics. We started with a set of 2,566 QSO candidates from our previous work selected…

Nonlinear Color-Metallicity Relations of Globular Clusters. III. On the Discrepancy in Metallicity between Globular Cluster Systems and their Parent Elliptical Galaxies

Suk-Jin Yoon, Sang-Yoon Lee, John P. Blakeslee +7

One of the conundrums in extragalactic astronomy is the discrepancy in observed metallicity distribution functions (MDFs) between the two prime stellar components of early-type gal…

Nonlinear Color-Metallicity Relations of Globular Clusters. II. A Test on the Nonlinearity Scenario for Color Bimodality Using the u-band Colors: The Case of M87 (NGC 4486)

Suk-Jin Yoon, Sangmo T. Sohn, Sang-Yoon Lee +4

The optical color distributions of globular clusters (GCs) in most large elliptical galaxies are bimodal. Based on the assumed linear relationship between GC colors and their metal…

A WFC3 study of globular clusters in NGC 4150 - an early-type minor merger

Sugata Kaviraj, R. Mark Crockett, Bradley C. Whitmore +8

We combine near-ultraviolet (NUV; 2250 Å) and optical (U, B, V, I) imaging from the Wide Field Camera 3 (WFC3), on board the Hubble Space Telescope (HST), to study the globular clu…

Improved and Quality-assessed Emission and Absorption Line measurements in Sloan Digital Sky Survey galaxies

Kyuseok Oh, Marc Sarzi, Kevin Schawinski +1

We present a new database of absorption and emission-line measurements based on the entire spectral atlas from the Sloan Digital Sky Survey (SDSS) 7th data release of galaxies with…

Evidence for 1000 km/s Molecular Outflows in the Local ULIRG Population

Aeree Chung, Min S. Yun, Gopal Naraynan +2

The feedback from galactic outflows is thought to play an important role in shaping the gas content, star formation history, and ultimately the stellar mass function of galaxies. H…

Caught in the Act: Strong, Active Ram Pressure Stripping in Virgo Cluster Spiral NGC 4330

Anne Abramson, Jeffrey D. P. Kenney, Hugh H. Crowl +4

We present a multi-wavelength study of NGC 4330, a highly-inclined spiral galaxy in the Virgo Cluster which is a clear example of strong, ongoing ICM-ISM ram pressure stripping. Th…
