1203.4775 (Marina Trevisan et al.)

Constraints on feedback processes during the formation of early-type galaxies    [PDF]

Marina Trevisan, Ignacio Ferreras, Ignacio de la Rosa, Francesco La Barbera, Reinaldo de Carvalho
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 curvature of scaling relations remain uncertain. In this letter, we focus on the specific family of early-type galaxies, deriving the star formation histories of a complete sample of visually classified galaxies from SDSS-DR7 over the redshift range 0.01View original: http://arxiv.org/abs/1203.4775
