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 ...
Energetic galaxy-wide outflows in high-redshift ultra-luminous infrared galaxies hosting AGN activity
(2012-05-08)
We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs) that host Active Galactic Nuclei (AGN) ...
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
(2013-07-24)
We present new [CI](1-0) and 12CO(4-3) Plateau de Bure Interferometer observations of five Sub-Millimeter Galaxies (SMGs) and combine these with all available [CI](1-0) literature detections in SMGs to probe the gas ...
Tracing the molecular gas in distant submillimetre galaxies via CO(1-0) imaging with the EVLA
(2010-09-03)
We report the results of a pilot study with the EVLA of 12CO J=1-0 emission from four SMGs at z=2.2-2.5, each with an existing detection of CO J=3-2. Using the EVLA's most compact configuration we detect strong, broad J=1-0 ...
AEGIS20: a radio survey of the Extended Groth Strip
(2007-05-01)
We describe AEGIS20 - a radio survey of the Extended Groth Strip (EGS) conducted with the Very Large Array (VLA) at 1.4GHz. The resulting catalog contains 1,123 emitters and is sensitive to ultraluminous starbursts to z1 ...
Molecular Gas in Submillimetre-Faint, Star-Forming Ultraluminous Galaxies at z>1
(2009-10-30)
[abridged] We present interferometric CO observations of twelve z~2 submillimetre-faint, star-forming radio galaxies (SFRGs) which are thought to be ultraluminous infrared galaxies (ULIRGs) possibly dominated by warmer ...
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 ...
SPT 0538-50: Physical conditions in the ISM of a strongly lensed dusty star-forming galaxy at z=2.8
(2013-09-12)
We present observations of SPT-S J053816-5030.8, a gravitationally-lensed dusty star forming galaxy (DSFG) at z = 2.7817, first discovered at millimeter wavelengths by the South Pole Telescope. SPT 0538-50 is typical of ...
Spectroscopic Characterisation of 250um-Selected Hyper-Luminous Star Forming Galaxies
(2010-09-28)
We present near-infrared spectroscopic observations from VLT ISAAC of thirteen 250\mu m-luminous galaxies in the CDF-S, seven of which have confirmed redshifts which average to = 2.0 \pm 0.4. Another two sources of the 13 ...
