The ATLAS 3D project - XVI. Physical parameters and spectral line energy distributions of the molecular gas in gas-rich early-type galaxies
Estelle Bayet, Martin Bureau, Timothy A. Davis +22
[Abridged] We present a detailed study of the physical properties of the molecular gas in a sample of 18 molecular gas-rich early-type galaxies (ETGs) from the ATLAS$ 3D sample. Ou…
The ATLAS3D project - XXII. Low-efficiency star formation in early-type galaxies: hydrodynamic models and observations
Marie Martig, Alison F. Crocker, Frederic Bournaud +27
We study the global efficiency of star formation in high resolution hydrodynamical simulations of gas discs embedded in isolated early-type and spiral galaxies. Despite using a uni…
The ATLAS3D Project - XXI. Correlations between gradients of local escape velocity and stellar populations in early-type galaxies
Nicholas Scott, Michele Cappellari, Roger L. Davies +22
We explore the connection between the local escape velocity, V_esc, and the stellar population properties in the ATLAS3D survey, a complete, volume-limited sample of nearby early-t…
The ATLAS3D project - XVII. Linking photometric and kinematic signatures of stellar discs in early-type galaxies
Davor Krajnovic, Katherine Alatalo, Leo Blitz +20
[Abridged] We analyse the morphological structures in galaxies of the ATLAS3D sample by fitting a single Sersic profile and decomposing all non-barred objects (180 of 260 objects)…
The Atlas3D project - XIV. The extent and kinematics of molecular gas in early-type galaxies
Timothy A. Davis, Katherine Alatalo, Martin Bureau +23
We use interferometric CO observations to compare the extent, surface brightness profiles and kinematics of the molecular gas in CO-rich Atlas3D early-type galaxies (ETGs) and spir…
The ATLAS3D project - XVIII. CARMA CO imaging survey of early-type galaxies
Katherine Alatalo, Timothy A. Davis, Martin Bureau +23
We present the Combined Array for Research in Millimeter Astronomy (CARMA) ATLAS3D molecular gas imaging survey, a systematic study of the distribution and kinematics of molecular…
