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…
Systematic variation of the 12CO/13CO ratio as a function of star-formation rate surface density
Timothy A. Davis
We show that the12CO/13CO intensity ratio in nearby galaxies varies systematically as a function of the star formation rate surface density and gas surface density. The same effect…
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…
A Thirty Kiloparsec Chain of "Beads on a String" Star Formation Between Two Merging Early Type Galaxies in the Core of a Strong-Lensing Galaxy Cluster
Grant R. Tremblay, Michael D. Gladders, Stefi A. Baum +10
New Hubble Space Telescope ultraviolet and optical imaging of the strong-lensing galaxy cluster SDSS J1531+3414 (z=0.335) reveals two centrally dominant elliptical galaxies partici…
