Exploring the Properties of the M31 Halo Globular Cluster System
(2011-02-02)
Following on from our discovery of a significant population of M31 outer halo globular clusters (GCs), and updates to the Revised Bologna Catalogue of M31 GCs, we investigate the GC system of M31 out to an unprecedented ...
Redshift Determination and CO Line Excitation Modeling for the Multiply-Lensed Galaxy HLSW-01
(2011-04-20)
We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel/SPIRE observations as part of the Herschel Multi-tiered ...
Dynamical Structure of the Molecular Interstellar Medium in an Extremely Bright, Multiply Lensed z 3 Submillimeter Galaxy Discovered with Herschel
(2011-05-20)
We report the detection of CO 5-4, 3-2, and 1-0 emission in the strongly lensed, Herschel/SPIRE-selected submillimeter galaxy (SMG) HLSW-01 at z=2.9574+/-0.0001, using the Plateau de Bure Interferometer, the Combined Array ...
Luminous Starbursts in the Redshift Desert at z 1-2: Star Formation Rates, Masses & Evidence for Outflows
(2011-08-01)
We present a spectroscopic catalogue of 40 luminous starburst galaxies at z=0.7--1.7 (median z=1.3). 19 of these are submillimetre galaxies (SMGs) and 21 are submillimetre-faint radio galaxies (SFRGs). This sample helps ...
An SZ-selected sample of the most massive galaxy clusters in the 2500-square-degree South Pole Telescope survey
(2011-01-06)
The South Pole Telescope (SPT) is currently surveying 2500 deg^2 of the southern sky to detect massive galaxy clusters out to the epoch of their formation using the Sunyaev-Zel'dovich (SZ) effect. This paper presents a ...
Density Variations in the NW Star Stream of M31
(2011-02-17)
The Pan Andromeda Archeological Survey (PAndAS) CFHT Megaprime survey of the M31-M33 system has found a star stream which extends about 120 kpc NW from the center of M31. The great length of the stream, and the likelihood ...
LBQS 0103-2753: A Binary Quasar in a Major Merger
(2011-09-07)
We present HST and UKIRT spectra and images of the 2 kpc binary quasar LBQS 0103-2753 (z=0.858). The HST images (V- and I-band) show tidal features demonstrating that this system is a major galaxy merger in progress. A ...
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). I: The UV luminosity function of the central 12 sq.deg
(2011-02-07)
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering about 40 sq. deg. in the far UV (FUV, lambda_eff=1539A, Delta-lambda=442A) and about 120 sq. deg. in the near UV ...
The M33 Globular Cluster System with PAndAS Data: The Last Outer Halo Cluster?
(2011-01-12)
We use CFHT/MegaCam data to search for outer halo star clusters in M33 as part of the Pan-Andromeda Archaeological Survey (PAndAS). This work extends previous studies out to a projected radius of 50 kpc and covers over 40 ...
The globular cluster NGC 2419: a crucible for theories of gravity
(2011-06-24)
We present the analysis of a kinematic data set of stars in the globular cluster NGC 2419, taken with Keck/DEIMOS. Combined with a reanalysis of deep HST and Subaru imaging data, which provide an accurate luminosity profile ...
