The temperature dependence of the far-infrared-radio correlation in the Herschel-ATLAS
(2014-12-11)
We use 10 387 galaxies from the Herschel Astrophysical TeraHertz Large Area Survey (H-ATLAS) to probe the far-infrared radio correlation (FIRC) of star-forming galaxies as a function of redshift, wavelength, and effective ...
Why z > 1 radio-loud galaxies are commonly located in protoclusters
(2014-11-21)
Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in proto-clusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, ...
Herschel-ATLAS: Far-infrared properties of radio-loud and radio-quiet quasars
(2014-08-01)
We have constructed a sample of radio-loud and radio-quiet quasars from the Faint Images Radio Sky at Twenty-one centimetres and the Sloan Digital Sky Survey Data Release 7, over the Herschel-ATLAS Phase 1 area (9h, 12h ...
Evolution in the bias of faint radio sources to z ~ 2.2
(2014-05-21)
Quantifying how the baryonic matter traces the underlying dark matter distribution is key to both understanding galaxy formation and our ability to constrain the cosmological model. Using the cross-correlation function of ...
The star formation history of mass-selected galaxies from the VIDEO survey
(2014-04-01)
We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data.We split the sample, which spans 0 < ...
Mergers as triggers for nuclear activity : A near-IR study of the close environment of AGN in the VISTA-VIDEO survey
(2014-03-21)
There is an ongoing debate concerning the driver of nuclear activity in galaxies, with active galactic nuclei (AGN) either being triggered by major or minor galactic mergers or, alternatively, through secular processes ...
The wide-field infrared survey explorer properties of complete samples of radio-loud active galactic nucleus
(2014-03-01)
We present an analysis of four complete samples of radio-loud active galactic nucleus (AGN; 3CRR, 2Jy, 6CE and 7CE) using near- and mid-IR data taken by theWide-field Infrared Survey Explorer (WISE). The combined sample ...
