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…
Basic Testing of the Duchamp Source Finder
Tobias Westmeier, Attila Popping, Paolo Serra
This paper presents and discusses the results of basic source finding tests in three dimensions (using spectroscopic data cubes) with Duchamp, the standard source finder for the Au…
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…
CIGALE: Code Investigating GALaxy Emission
Yannick Roehlly, Denis Burgarella, Véronique Buat +3
We present CIGALE (Burgarella et al. 2005; Noll et al. 2009), a software developed at the Laboratoire d'Astrophysique de Marseille to fit galaxy spectral energy distributions from…
The ATLAS3D Project-- VIII: Modelling the Formation and Evolution of Fast and Slow Rotator Early-Type Galaxies within CDM
Sadegh Khochfar, Eric Emsellem, Paolo Serra +22
We propose a simple model for the origin of fast and slow rotator early-type galaxies (ETG) within the hierarchical CDM scenario, that is based on the assumption that the mass f…
The Atlas3D project - X. On the origin of the molecular and ionised gas in early-type galaxies
Timothy A. Davis, Katherine Alatalo, Marc Sarzi +22
We make use of interferometric CO and HI observations, and optical integral-field spectroscopy to probe the origin of the molecular and ionised interstellar medium (ISM) in local e…
