Galaxy and Mass Assembly (GAMA): Accurate number densities & environments of massive ultracompact galaxies at 0.02 < z < 0.3
F. Buitrago, I. Ferreras, L. S. Kelvin +15
Massive Ultracompact Galaxies (MUGs) are common at z=2-3, but very rare in the nearby Universe. Simulations predict that the few surviving MUGs should reside in galaxy clusters, wh…
A -band selected catalogue of objects in the ALHAMBRA survey
L. Nieves-Seoane, A. Fernandez-Soto, P. Arnalte-Mur +31
The original ALHAMBRA catalogue contained over 400,000 galaxies selected using a synthetic F814W image, to the magnitude limit AB(F814W)24.5. Given the photometric redshif…
Chronos: A NIR spectroscopic galaxy survey. From the formation of galaxies to the peak of activity
I. Ferreras, R. Sharples, J. S. Dunlop +30
Chronos is our response to ESA's call for white papers to define the science for the future L2, L3 missions. Chronos targets the formation and evolution of galaxies, by collecting…
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…
