GALEX Ultraviolet Photometry of Globular Clusters in M31: Three Year Results and a Catalog
Soo-Chang Rey, R. Michael Rich, Sangmo T. Sohn +23
We present ultraviolet (UV) photometry of M31 globular clusters (GCs) found in 23 Galaxy Evolution Explorer (GALEX) images covering the entirety of M31. We detect 485 and 273 GCs (…
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…
Search for Small Trans-Neptunian Objects by the TAOS Project
W. P. Chen, C. Alcock, T. Axelrod +24
The Taiwan-America Occultation Survey (TAOS) aims to determine the number of small icy bodies in the outer reach of the Solar System by means of stellar occultation. An array of 4…
First stars as a possible origin for the helium-rich population in omega Centauri
Ena Choi, Sukyoung K. Yi
The most massive Galactic globular cluster omega Cen appears to have two, or perhaps more, distinct main sequences. Its bluest main sequence is at the centre of debate because it h…
Broadband UBVRI Photometry of Horizontal-Branch and Metal-Poor Candidates from the HK and Hamburg/ESO Surveys. I
Timothy C. Beers, Chris Flynn, Silvia Rossi +17
We report broadband UBV and/or BVRI CCD photometry for a total of 1857 stars in the thick-disk and halo populations of the Galaxy. The majority of our targets were selected as cand…
The Local Universe as Seen in Far-Infrared and in Far-Ultraviolet: A Global Point of View on the Local Recent Star Formation
V. Buat, T. T. Takeuchi, J. Iglesias-Paramo +23
We select far-infrared (FIR-60 microns) and far-ultraviolet (FUV-1530 A) samples of nearby galaxies in order to discuss the biases encountered by monochromatic surveys (FIR or FUV)…
Ongoing Formation of Bulges and Black Holes in the Local Universe: New Insights from GALEX
Guinevere Kauffmann, Timothy M. Heckman, Tamas Budavari +21
We analyze a volume-limited sample of massive bulge-dominated galaxies with data from both the Sloan Digital Sky Survey and the Galaxy Evolution Explorer (GALEX) satellite. The gal…
Radial variation of attenuation and star formation in the largest late-type disks observed with GALEX
Samuel Boissier, Armando Gil de Paz, Alessandro Boselli +24
For a sample of 43 nearby, late-type galaxies, we have investigated the radial variation of both the current star formation rate and the dust-induced UV light attenuation. To do th…
The Diverse Properties of the Most Ultraviolet Luminous Galaxies Discovered by the Galaxy Evolution Explorer
Charles G. Hoopes, Timothy M. Heckman, Samir Salim +21
We report on the properties of a sample of ultraviolet luminous galaxies (UVLGs) selected by matching the Galaxy Evolution Explorer (GALEX) Surveys with the Sloan Digital Sky Surve…
GALEX UV Color Relations for Nearby Early-Type Galaxies
Jose Donas, Jean-Michel Deharveng, R. Michael Rich +23
We use GALEX/optical photometry to construct color-color relationships for early-type galaxies sorted by morphological type. We have matched objects in the GALEX GR1 public release…
Suppression of star formation in early-type galaxies by feedback from supermassive black holes
Kevin Schawinski, Sadegh Khochfar, Sugata Kaviraj +21
Detailed high-resolution observations of the innermost regions of nearby galaxies have revealed the presence of supermassive black holes1. These black holes may interact with their…
Star formation and figure rotation in the early-type galaxy NGC2974
Hyunjin Jeong, Martin Bureau, Sukyoung Ken Yi +2
We present Galaxy Evolution Explorer (GALEX) far (FUV) and near (NUV) ultraviolet imaging of the nearby early-type galaxy NGC2974, along with complementary ground-based optical ima…
The GALEX Ultraviolet Atlas of Nearby Galaxies
A. Gil de Paz, S. Boissier, B. F. Madore +23
We present images, integrated photometry, surface-brightness and color profiles for a total of 1034 nearby galaxies recently observed by the GALEX satellite in its far-ultraviolet…
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…
UV and FIR selected star-forming galaxies at z=0: differences and overlaps
C. Kevin Xu, Veronique Buat, Jorge Iglesias-Páramo +22
We study two samples of local galaxies, one is UV (GALEX) selected and the other FIR (IRAS) selected, to address the question whether UV and FIR surveys see the two sides ('bright'…
Explaining the Color Distributions of Globular Cluster Systems in Elliptical Galaxies
Suk-Jin Yoon, Sukyoung Ken Yi, Young-Wook Lee
The colors of globular clusters in most of large elliptical galaxies are bimodal. This is generally taken as evidence for the presence of two cluster subpopulations that have diffe…
The effect of environment on the UV colour-magnitude relation of early-type galaxies
K. Schawinski, S. Kaviraj, S. Khochfar +23
We use \textit{GALEX} (Galaxy Evolution Explorer) near-UV (NUV) photometry of a sample of early-type galaxies selected in \textit{SDSS} (Sloan Digital Sky Survey) to study the UV c…
