The ATLAS3D project - XXIV : The intrinsic shape distribution of early-type galaxies
(2014-11-11)
We use the ATLAS<sup>3D</sup> sample to perform a study of the intrinsic shapes of early-type galaxies, taking advantage of the available combined photometric and kinematic data. Based on our ellipticity measurements from ...
The angular clustering of infrared-selected obscured and unobscured quasars
(2014-08-21)
Recent studies of luminous infrared-selected active galactic nuclei (AGN) suggest that the reddest, most obscured objects display a higher angular clustering amplitude, and thus reside in higher mass darkmatter haloes. ...
An X-ray survey of the 2 Jy sample-I : Is there an accretion mode dichotomy in radio-loud AGN?
(2014-05-01)
We carry out a systematic study of the X-ray emission from the active nuclei of the 0.02 < z< 0.7 2 Jy sample, using Chandra and XMM-Newton observations.We combine our results with those from mid-infrared, optical emission-line ...
The impact of a young radio galaxy : Clues from the cosmic ray electron population
(2014-04-01)
In the framework of hierarchical structure formation, active galactic nuclei (AGN) feedback shapes the galaxy luminosity function. Low luminosity, galaxy-scale double radio sources are ideal targets to investigate the ...
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 ...
The mass-metallicity relation at z 1.4 revealed with Subaru/FMOS
(2014-02-01)
We present a stellar mass-metallicity relation at z ~ 1.4 with an unprecedentedly large sample of ~340 star-forming galaxies obtained with FibreMulti-Object Spectrograph (FMOS) on the Subaru Telescope. We observed K-band ...
Star formation and agn activity in interacting galaxies : A near-UV perspective
(2014-01-21)
We study nearby galaxies in close pairs to study the key factors affecting star formation and active galactic nuclei (AGN) activity triggered during galaxy interactions. Close pairs are selected from the Sloan Digital Sky ...
