Probing Shock Breakout with Serendipitous GALEX Detections of Two SNLS Type II-P Supernovae
Suvi Gezari, Luc Dessart, Stephane Basa +13
We report the serendipitous detection by GALEX of fast (<1 day) rising (>1 mag) UV emission from two Type II plateau (II-P) supernovae (SNe) at z=0.185 and 0.324 discovered by the…
Lyman alpha emitting galaxies at 0.2 < z < 0.35 from GALEX spectroscopy
Jean-Michel Deharveng, Todd Small, Tom A. Barlow +19
The GALEX (Galaxy Evolution Explorer) spectroscopic survey mode, with a resolution of about 8 A in the FUV (1350 - 1750 A) and about 20 A in the NUV (1950 - 2750 A) is used for a s…
Ultraviolet, Optical, and Infrared Constraints on Models of Stellar Populations and Dust Attenuation
Benjamin D. Johnson, David Schiminovich, Mark Seibert +19
The color of galaxies is a fundamental property, easily measured, that constrains models of galaxies and their evolution. Dust attenuation and star formation history (SFH) are the…
The UV-Optical Color Magnitude Diagram II: Physical Properties and Morphological Evolution On and Off of a Star-Forming Sequence
David Schiminovich, Ted K. Wyder, D. Christopher Martin +23
We use the UV-optical color magnitude diagram in combination with spectroscopic and photometric measurements derived from the SDSS spectroscopic sample to measure the distribution…
The Young and the Dustless: Interpreting Radio Observations of UltraViolet Luminous Galaxies
Antara R. Basu-Zych, David Schiminovich, Benjamin D. Johnson +23
Ultraviolet Luminous Galaxies (UVLGs) have been identified as intensely star-forming, nearby galaxies. A subset of these, the supercompact UVLGs, are believed to be local analogs o…
Nitrogen Production in Starburst Galaxies Detected by GALEX
Ryan P. Mallery, Lisa Kewley, R. Michael Rich +22
We investigate the production of nitrogen in star forming galaxies with ultraviolet (UV) radiation detected by the Galaxy Evolution Explorer Satellite (GALEX). We use a sample of 8…
UV Star Formation Rates in the Local Universe
Samir Salim, R. Michael Rich, Stéphane Charlot +21
We measure star formation rates of ~50,000 optically-selected galaxies in the local universe (z~0.1), spanning a range from gas-rich dwarfs to massive ellipticals. We obtain dust-c…
Statistical Properties of the GALEX/SDSS matched source catalogs, and classification of the UV sources
Luciana Bianchi, Lino Rodriguez-Merino, Maurice Viton +30
We use the Galaxy Evolution Explorer (GALEX) Medium and All-Sky-Imaging Survey (MIS & AIS) data from the first public data release (GR1), matched to the Sloan Digital Sky Survey (S…
Dissecting Galaxy Colors with GALEX, SDSS, and Spitzer
B. D. Johnson, D. Schiminovich, M. Seibert +21
We combine data from SDSS and the GALEX and Spitzer observatories to create a sample of galaxies observed homogeneously from the UV to the Far-IR. This sample, consisting of ~460 g…
Discovery of an extended ultraviolet disk in the nearby galaxy NGC4625
A. Gil de Paz, B. F. Madore, S. Boissier +8
Recent far-UV (FUV) and near-UV (NUV) observations of the nearby galaxy NGC4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended UV disk reaching 4 ti…
Classification and Characterization of Objects from GALEX and SDSS surveys
Luciana Bianchi, M. Seibert, W. Zheng +22
We use the GALEX (Galaxy Evolution Explorer) Medium Imaging Survey (MIS) and All-Sky Imaging Survey (AIS) data available in the first internal release, matched to the SDSS catalogs…
The GALEX-VVDS Measurement of the Evolution of the 1500A Luminosity Function
S. Arnouts, D. Schiminovich, O. Ilbert +8
We present the first measurement of the galaxy luminosity function at 1500A between 0.2<z<1.2 based on GALEX-VVDS observations (1000 spectroscopic redshifts for galaxies with NUV<2…
UV Morphology and Star Formation in the Tidal Tails of NGC 4038/39
J. E. Hibbard, L. Bianchi, D. A. Thilker +2
We present GALEX FUV (1530 A) and NUV (2310 A) observations of the archetypal merging system NGC 4038/39, ``The Antennae". Both tails are relatively bright in the UV, especially in…
GALEX UV Color-Magnitude Relations and Evidence for Recent Star Formation in Early-type Galaxies
S Yi, SJ Yoon, S Kaviraj +32
We have used the GALEX UV photometric data to construct a first near-ultraviolet (NUV) color-magnitude relation (CMR) for the galaxies pre-classified as early-type by SDSS studies.…
UV emission and Star Formation in Stephan's Quintet
C. Kevin Xu, Jorge Iglesias-Paramo, Denis Burgarella +22
we present the first GALEX UV images of the well known interacting group of galaxies, Stephan's Quintet (SQ). We detect widespread UV emission throughout the group. However, there…
Recent Star Formation in the Extreme Outer Disk of M83
D. A. Thilker, L. Bianchi, S. Boissier +24
Ultraviolet imaging with the Galaxy Evolution Explorer (GALEX) has revealed an extensive sample of UV-bright stellar complexes in the extreme outer disk of M83, extending to about…
