Suppression of Star Formation in NGC 1266
K. Alatalo, M. Lacy, L. Lanz +11
NGC1266 is a nearby lenticular galaxy that harbors a massive outflow of molecular gas powered by the mechanical energy of an active galactic nucleus (AGN). It has been speculated t…
The Atlas3D project -- XXIX. The new look of early-type galaxies and surrounding fields disclosed by extremely deep optical images
Pierre-Alain Duc, Jean-Charles Cuillandre, Emin Karabal +24
Galactic archeology based on star counts is instrumental to reconstruct the past mass assembly of Local Group galaxies. The development of new observing techniques and data-reducti…
Connection between dynamically derived IMF normalisation and stellar population parameters
Richard M. McDermid, Michele Cappellari, Katherine Alatalo +22
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…
The Atlas3D project - XXIV. The intrinsic shape distribution of early-type galaxies
Anne-Marie Weijmans, P. T. de Zeeuw, Eric Emsellem +23
We use the Atlas3D 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…
Large scale kinematics and dynamical modelling of the Milky Way nuclear star cluster
A. Feldmeier, N. Neumayer, A. Seth +6
Within the central 10pc of our Galaxy lies a dense nuclear star cluster (NSC), and similar NSCs are found in most nearby galaxies. Studying the structure and kinematics of NSCs rev…
The ATLAS3D Project - XXVIII. Dynamically-driven star formation suppression in early-type galaxies
Timothy A. Davis, Lisa M. Young, Alison F. Crocker +22
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) 22um and Galax…
The Atlas3D project - XXVI. HI discs in real and simulated fast and slow rotators
Paolo Serra, Ludwig Oser, Davor Krajnovic +24
One quarter of all nearby early-type galaxies (ETGs) outside Virgo host a disc/ring of HI with size from a few to tens of kpc and mass up to ~1e+9 solar masses. Here we investigate…
