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 ...
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 ...
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) ...
Herschel-ATLAS/GAMA: A difference between star formation rates in strong-line and weak-line radio galaxies
(2013-03)
We have constructed a sample of radio-loud objects with optical spectroscopy from the Galaxy and Mass Assembly (GAMA) project over the Herschel Astrophysical Terahertz Large Area Survey (Herschel-ATLAS) Phase 1 fields. ...
Star formation in high-redshift quasars : Excess [Oii] emission in the radio-loud population
(2012-12-11)
We investigate the [O ii] emission-line properties of 18 508 quasars at z < 1.6 drawn from the Sloan Digital Sky Survey (SDSS) quasar sample. The quasar sample has been separated into 1692 radio-loud and 16 816 radio-quiet ...
Herschel-ATLAS : the far-infrared properties and star-formation rates of broad absorption line quasi-stellar objects
(2012-12-01)
We have used data from the Herschel Astrophysical Terahertz Large-Area Survey (H-ATLAS) at 250, 350 and 500 μm to determine the far-infrared (FIR) properties of 50 broad absorption line quasars (BAL QSOs)
Herschel-ATLAS: the link between accretion luminosity and star formation in quasar host galaxies
(2011-09)
We use the science demonstration field data of the Herschel Astrophysical Terahertz Large Area Survey to study how star formation, traced by the far-infrared Herschel data, is related to both the accretion luminosity and ...
The Herschel ATLAS
(2010-05-01)
The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 570 deg2 of the extragalactic sky, 4 times larger than all the other Herschel extragalactic ...
