The ATLAS3D project - XXIX : The new look of early-type galaxies and surrounding fields disclosed by extremely deep optical images
(2015-01)
Galactic archaeology based on star counts is instrumental to reconstruct the past mass assembly of Local Group galaxies. The development of new observing techniques and data reduction, coupled with the use of sensitive ...
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 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 - 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 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) ...
Connection between dynamically derived initial mass function normalization and stellar population parameters
(2014-09-10)
We report on empirical trends between the dynamically determined stellar initial mass function (IMF) and stellar population properties for a complete, volume-limited sample of 260 early-type galaxies from the ATLAS3D ...
NGC 1266 as a local candidate for rapid cessation of star formation
(2014-01-10)
We present new Spectrographic Areal Unit for Research on Optical Nebulae (SAURON) integral-field spectroscopy and Swift Ultraviolet Optical Telescope (UVOT) observations of molecular outflow host galaxy NGC 1266 that ...
The ATLAS project - XII : Recovery of the mass-to-light ratio of simulated early-type barred galaxies with axisymmetric dynamical models
(2012-08)
We investigate the accuracy in the recovery of the stellar dynamics of barred galaxies when using axisymmetric dynamical models. We do this by trying to recover the mass-to-light ratio (M/L) and the anisotropy of realistic ...
The ATLAS(3D) project-XIII. : mass and morphology of HI in early-type galaxies as a function of environment
(2012-05)
We present the ATLAS3D H i survey of a volume-limited, complete sample of 166 nearby early-type galaxies (ETGs) brighter than MK=-21.5. The survey is mostly based on data taken with the Westerbork Synthesis Radio Telescope, ...
