Exploring the Star Formation History of Elliptical Galaxies: Beyond Simple Stellar Populations with a New Estimator of Line Strengths
Ben Rogers, Ignacio Ferreras, Reynier F. Peletier +1
(Abridged) We study the stellar populations of 14 elliptical galaxies in the Virgo cluster. We propose an alternative approach to the standard side-band method to measure equivalen…
The formation history of the Galactic bulge
I. Ferreras, R. F. G. Wyse, J. Silk
The distributions of the stellar metallicities of K giant stars in several fields of the Galactic bulge, taken from the literature are compared with a simple model of star formatio…
On breaking the age-metallicity degeneracy in early-type galaxies: Outflows versus Star Formation Efficiency
I. Ferreras, J. Silk
A simple model of chemical enrichment in cluster early-type galaxies is presented where the main parameters driving the formation of the stellar component are reduced to four: infa…
Quasars and Galaxy Formation
Joseph Silk, Martin J. Rees
The formation of massive black holes may precede the epoch that characterises the peak of galaxy formation, as characterized by the star formation history in luminous galaxies. Hen…
