Evolution of faint radio sources in the VIDEO-XMM3 field
(2013-12-01)
It has been speculated that low-luminosity radio-loud active galactic nuclei (AGN) have the potential to serve as an important source of AGN feedback, and may be responsible for suppressing star formation activity in massive ...
Isothermal dust models of Herschel-ATLAS galaxies
(2013-12)
We use galaxies from the Herschel-ATLAS (H-ATLAS) survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity ...
A 325-MHz GMRT survey of the Herschel-ATLAS/GAMA fields
(2013-10-01)
We describe a 325-MHz survey, undertaken with the Giant Metrewave Radio Telescope (GMRT), which covers a large part of the three equatorial fields at 9, 12 and 14.5 h of right ascension from the Herschel-Astrophysical ...
Evolution of star formation in the UKIDSS ultra deep survey field-I. Luminosity functions and cosmic star formation rate out to z = 1.6
(2013-07-21)
We present new results on the cosmic star formation history in the Subaru/XMM-Newton Deep Survey (SXDS)-Ultra Deep Survey (UDS) field out to z = 1.6. We compile narrowband data from the Subaru Telescope and the Visible and ...
Herschel-ATLAS/GAMA : the environmental density of far-infrared bright galaxies at z < 0.5
(2013-07)
We compare the environmental and star formation properties of far-infrared detected and non-far-infrared detected galaxies out to z similar to 0.5. Using optical spectroscopy and photometry from the Galaxy And Mass Assembly ...
Radio-Loud Active Galactic Nucleus : is there a link between luminosity and cluster environment?
(2013-06-20)
We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project, characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z similar to 0.5 ...
Herschel-ATLAS/GAMA: What determines the far-infrared properties of radio galaxies?
(2013-06)
We perform a stacking analysis of Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) data in order to obtain isothermal dust temperatures and rest-frame luminosities at 250 mu m (L-250), for a well-defined sample ...
Galaxy Clusters around Radio-loud Active Galactic Nuclei at 1.3 lt z lt 3.2 as seen by Spitzer
(2013-05-01)
We report the first results from the Clusters Around Radio-Loud AGN program, a Cycle 7 and 8 Spitzer Space Telescope snapshot program to investigate the environments of a large sample of obscured and unobscured luminous ...
VLT/XSHOOTER and Subaru/MOIRCS spectroscopy of HUDF.YD3 : no evidence for Lyman α emission at z = 8.55
(2013-04-21)
We present spectroscopic observations with VLT/XSHOOTER and Subaru/MOIRCS of a relatively bright Y-band drop-out galaxy in the Hubble Ultra Deep Field (HUDF), first selected by Bunker et al., McLure et al. and Bouwens et ...
Mining the Herschel-astrophysical terahertz large area survey : Submillimetre-selected blazars in equatorial fields
(2013-04-11)
The Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS) provides an unprecedented opportunity to search for blazars at sub-mm wavelengths. We cross-matched the Faint Images of the Radio Sky at Twenty-cm (FIRST) ...
