Stellar and total mass in early-type lensing galaxies
Ignacio Ferreras, Prasenjit Saha, Liliya L. R. Williams
For 18 well-observed gravitationally lensed QSOs, we compare new non-parametric mass profiles for the lensing galaxies with stellar-population models derived from published HST pho…

Backwards galaxy formation with only a few parameters
I. Ferreras, J. Silk
We present a simple phenomenological model of star formation in galaxies that describes the process with a set of a few parameters. The star formation efficiency and the fraction o…

How young are early-type cluster galaxies ? Quantifying the young stellar component in a rich cluster at z=0.41
I. Ferreras, J. Silk
We present a new method of quantifying the mass fraction of young stars in galaxies by analyzing near-ultraviolet (NUV)-optical colors. We focus our attention on early-type cluster…
