The ATLAS3D project - XXV : Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators
(2014-11-11)
We present a detailed two-dimensional stellar dynamical analysis of a sample of 44 cosmological hydrodynamical simulations of individual central galaxies with stellar masses of 2 × 1010 M⊙ ≲ M* ≲ 6 × 1011 M⊙. Kinematic ...
STREGA: STRucture and Evolution of the GAlaxy - I : Survey overview and first results
(2014-11-11)
STREGA (STRucture and Evolution of the GAlaxy) is a guaranteed time survey being performed at the VST (the ESO Very Large Telescope Survey Telescope) to map about 150 square degrees in the Galactic halo, in order to constrain ...
The ATLAS3D project - XXVII : Cold gas and the colours and ages of early-type galaxies
(2014-11-11)
We present a study of the cold gas contents of the ATLAS3D early-type galaxies, in the context of their optical colours, near-ultraviolet colours and Hβ absorption line strengths. Early-type (elliptical and lenticular) ...
The first planet detected in the WTS : an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
(2014-11-11)
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in August 2007. Light curves comprising ...
The ATLAS3D Project - XXVIII : Dynamically driven star formation suppression in early-type galaxies
(2014-11-11)
We present measurements of the star formation rate (SFR) in the early-type galaxies (ETGs) of the ATLAS3D sample, based on Wide-field Infrared Survey Explorer (WISE) 22 μm and Galaxy Evolution Explorer far-ultraviolet ...
The second data release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS DR2)
(2014-11-11)
The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes ℓ = 30°–215° in the r, i, and Hα filters using the Wide Field Camera ...
The ATLAS3D project - XXVI : H I discs in real and simulated fast and slow rotators
(2014-11-11)
One quarter of all nearby early-type galaxies (ETGs) outside Virgo host a disc/ring of H I with size from a few to tens of kpc and mass up to ∼109 M⊙. Here we investigate whether this H I is related to the presence of a ...
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 ...
GALAPAGOS-C : Analysis of galaxy morphologies using high-performance computing methods
(2014-11-11)
We present GALAPAGOS-C, a code designed to process a complete set of survey images through automation of source detection (via SEXTRACTOR), postage stamp cutting, object mask preparation, sky background estimation and ...
