The SAURON project XVI: On the Sources of Ionisation for the Gas in Elliptical and Lenticular Galaxies

Marc Sarzi, Joseph C. Shields, Kevin Schawinski +16

Following our study on the incidence, morphology and kinematics of the ionised gas in early-type galaxies we now address the question of what is powering the observed nebular emiss…

The Local Hosts of Type Ia Supernovae

James D. Neill, Mark Sullivan, D. Andy Howell +18

We use multi-wavelength, matched aperture, integrated photometry from GALEX, SDSS and the RC3 to estimate the physical properties of 166 nearby galaxies hosting 168 well-observed T…

12co(J=1-0) on-the-Fly Mapping Survey of the Virgo Cluster Spirals. I. Data and Atlas

E. J. Chung, M. -H. Rhee, H. Kim +3

We have performed an On-The-Fly (OTF) mapping survey of emission in 28 Virgo cluster spiral galaxies using the Five College Radio Astronomy Observatory (FC…

Tidal Dwarf Galaxies around a Post-merger Galaxy, NGC 4922

Yun-Kyeong Sheen, Hyunjin Jeong, Sukyoung K. Yi +20

One possible channel for the formation of dwarf galaxies involves birth in the tidal tails of interacting galaxies. We report the detection of a bright UV tidal tail and several yo…

Reddening and Distance of the Local Group Starburst Galaxy IC 10

Minsun Kim, Eunhyeuk Kim, Narae Hwang +5

We estimate the reddening and distance of the nearest starburst galaxy IC 10 using deep near infrared photometry obtained with the Multi-Object InfraRed Camera and Spectr…

Probing the Intermediate-Age Globular Clusters in NGC 5128 from Ultraviolet Observations

Soo-Chang Rey, Sangmo T. Sohn, Michael A. Beasley +23

We explore the age distribution of the globular cluster (GC) system of the nearby elliptical galaxy NGC 5128 using ultraviolet (UV) photometry from Galaxy Evolution Explorer (GALEX…

Spatial Clustering from GALEX-SDSS samples: Star Formation History and large-scale clustering

Sebastien Heinis, Tamas Budavari, Alex S. Szalay +19

We measure the projected spatial correlation function w_p(r_p) from a large sample combining GALEX ultraviolet imaging with the SDSS spectroscopic sample. We study the dependence o…

GALEX-SDSS Catalogs for Statistical Studies

T. Budavari, S. Heinis, A. S. Szalay +23

We present a detailed study of the Galaxy Evolution Explorer's photometric catalogs with special focus on the statistical properties of the All-sky and Medium Imaging Surveys. We i…

The Fundamental Planes of E+A galaxies and GALEX UV-excess early-type galaxies: Revealing their intimate connection

Yumi Choi, Tomotsugu Goto, Suk-Jin Yoon

Strong Balmer absorption lines and the lack of Ha and [OII] emission lines signify that E+As are post-starburst systems. Recent studies suggest that E+As may undergo the transition…

Old stellar population synthesis: New age and mass estimates for Mayall II = G1

Jun Ma, Richard de Grijs, Zhou Fan +3

Mayall II = G1 is one of the most luminous globular clusters (GCs) in M31. Here, we determine its age and mass by comparing multicolor photometry with theoretical stellar populatio…

Galaxy Zoo: A sample of blue early-type galaxies at low redshift

Kevin Schawinski, Chris Lintott, Daniel Thomas +13

We report the discovery of a population of nearby, blue early-type galaxies with high star formation rates (0.5 < SFR < 50 Msun/yr). They are identified by their visual morphology…

The Star Formation Law at Low Surface Density

Ted K. Wyder, D. Christopher Martin, Tom A. Barlow +16

We investigate the nature of the star formation law at low gas surface densities using a sample of 19 low surface brightness (LSB) galaxies with existing HI maps in the literature,…

The SINS survey: SINFONI Integral Field Spectroscopy of z ~ 2 Star-forming Galaxies

N. M. Forster Schreiber, R. Genzel, N. Bouche +27

We present the SINS survey with SINFONI of high redshift galaxies. With 80 objects observed and 63 detected, SINS is the largest survey of spatially resolved gas kinematics, morpho…
