SPIDER VII - Revealing the Stellar Population Content of Massive Early-type Galaxies out to 8Re
F. La Barbera, I. Ferreras, R. R. de Carvalho +4
Radial trends of stellar populations in galaxies provide a valuable tool to understand the mechanisms of galaxy growth. In this paper, we present the first comprehensive analysis o…
Spatially Resolved Colors and Stellar Population Properties in Early-Type Galaxies at z ~ 1.5
A. Gargiulo, P. Saracco, M. Longhetti +2
We present F850LP-F160W color gradients for 11 early-type galaxies (ETGs) at 1.0<z_spec<1.9. Significant negative F850LP-F160W color gradients have been detected in ~70% of our sam…
Systematic variation of the stellar Initial Mass Function with velocity dispersion in early-type galaxies
I. Ferreras, F. La Barbera, R. R. de Carvalho +4
An essential component of galaxy formation theory is the stellar initial mass function (IMF), that describes the parent distribution of stellar mass in star forming regions. We pre…
Formation and Evolution of Early-Type Galaxies. III Star formation history as a function of mass and over-density
Emiliano Merlin, Cesare Chiosi, Lorenzo Piovan +3
We investigate the influence of the initial proto-galaxies over-densities and masses on their evolution, to understand whether the internal properties of the proto-galactic haloes…
Constraints on feedback processes during the formation of early-type galaxies
Marina Trevisan, Ignacio Ferreras, Ignacio de la Rosa +2
Galaxies are found to obey scaling relations between a number of observables. These relations follow different trends at the low- and the high-mass ends. The processes driving the…
Characterizing the nature of Fossil Groups with XMM
F. La Barbera, M. Paolillo, E. De Filippis +1
We present an X-ray follow-up, based on XMM plus Chandra, of six Fossil Group (FG) candidates identified in our previous work using SDSS and RASS data. Four candidates (out of six)…
