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…
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…
The All-wavelength Extended Groth Strip International Survey (AEGIS) Data Sets
M. Davis, P. Guhathakurta, N. Konidaris +53
In this the first of a series of Letters, we present a description of the panchromatic data sets that have been acquired in the Extended Groth Strip region of the sky. Our survey,…
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…
The Metal-Poor Halo of the Andromeda Spiral Galaxy (M31)
J. S. Kalirai, K. M. Gilbert, P. Guhathakurta +6
We present spectroscopic observations of red giant branch (RGB) stars over a large expanse in the halo of the Andromeda spiral galaxy (M31), acquired with the DEIMOS instrument on…
High resolution infrared spectroscopy of the old open cluster NGC6791
L. Origlia, E. Valenti, R. M. Rich +1
We report abundance analysis for 6 M giant members of the old open cluster NGC6791, based on infrared spectroscopy (1.5-1.8 micron) at R=25,000, using the NIRSPEC spectrograph at t…
GALEX Observations of "Passive Spirals" in the Cluster Cl 0024+17: Clues to the Formation of S0 Galaxies
Sean M. Moran, Richard S. Ellis, Tommaso Treu +4
We present new results from deep GALEX UV imaging of the cluster Cl 0024+17 at z~0.4. Rest-frame far UV emission is detected from a large fraction of so-called ``passive spiral gal…
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…
Star formation in the nearby universe: the ultraviolet and infrared points of view
J. Iglesias-Paramo, V. Buat, T. T. Takeuchi +27
This work presents the main ultraviolet (UV) and far-infrared (FIR) properties of two samples of nearby galaxies selected from the GALEX (Å, hereafter NUV) and IRAS ($λ= 6…
Better age estimations using UV-optical colours: breaking the age-metallicity degeneracy
S. Kaviraj, S. -C. Rey, R. M. Rich +3
We demonstrate that the combination of GALEX UV photometry in the FUV (~1530 angstroms) and NUV (~2310 angstroms) passbands with optical photometry in the standard U,B,V,R,I filter…
UV-optical colours as probes of early-type galaxy evolution
S. Kaviraj, K. Schawinski, J. E. G. Devriendt +25
We have studied ~2100 early-type galaxies in the SDSS DR3 which have been detected by the GALEX Medium Imaging Survey (MIS), in the redshift range 0 < z < 0.11. Combining GALEX UV…
