The Atlas3D Project -- XI. Dense molecular gas properties of CO-luminous early-type galaxies
Alison Crocker, Melanie Krips, Martin Bureau +24
Surveying eighteen 12CO-bright galaxies from the ATLAS3D early-type galaxy sample with the Institut de Radio Astronomie Millimétrique (IRAM) 30m telescope, we detect 13CO(1-0) and…
Spectral models of stellar populations resolved in chemical abundances
Philippe Prugniel, Mina Koleva
We present model spectra of stellar populations with variable chemical composition. We derived the [alpha/Fe] abundance ratio of the stars of the most important libraries (ELODIE,…
Backreaction in late-time cosmology
Thomas Buchert, Syksy Rasanen
We review the effect of the formation of nonlinear structures on the expansion rate, spatial curvature and light propagation in the universe, focusing on the possibility that it co…
Feeding compact bulges and supermassive black holes with low angular-momentum cosmic gas at high redshift
Yohan Dubois, Christophe Pichon, Martin Haehnelt +4
We use cosmological hydrodynamical simulations to show that a significant fraction of the gas in high redshift rare massive halos falls nearly radially to their very centre on extr…
Stellar population models in the UV: I. Characterisation of the New Generation Stellar Library
Mina Koleva, Alexander Vazdekis Vazdekis
The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quali…
The Atlas3D project -- XIII. Mass and morphology of HI in early-type galaxies as a function of environment
Paolo Serra, Tom Oosterloo, Raffaella Morganti +23
We present the Atlas3D HI survey of 166 nearby early-type galaxies (ETGs) down to M(HI)~10^7 M_sun. We detect HI in ~40% of all ETGs outside the Virgo cluster and in ~10% of all ET…
