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…
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…
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)…
