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 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 - 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 ...
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 ...
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 ...
