Constraints on the merging channel of massive galaxies since z~1
I. Ferreras, I. Trujillo, E. Mármol-Queraltó +8
(Abridged) We probe the merging channel of massive galaxies over the z=0.3-1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass >1E11Msun, from…
The (galaxy-wide) IMF in giant elliptical galaxies: From top to bottom
Carsten Weidner, Ignacio Ferreras, Alexandre Vazdekis +1
Recent evidence based independently on spectral line strengths and dynamical modelling point towards a non-universal stellar Initial Mass Function (IMF), probably implying an exces…
SHARDS: stellar populations and star formation histories of a mass-selected sample of 0.65<z<1.1 galaxies
Antonio Hernán-Caballero, Almudena Alonso-Herrero, Pablo G. Pérez-González +10
We report on results from the analysis of a stellar mass-selected (log M*>9.0) sample of 1644 galaxies at 0.65<z<1.1 with ultra-deep (m<26.5) optical medium-band (R~50) photometry…
SPIDER VIII - Constraints on the Stellar Initial Mass Function of Early-type Galaxies from a Variety of Spectral Features
F. La Barbera, I. Ferreras, A. Vazdekis +5
We perform a spectroscopic study to constrain the stellar Initial Mass Function (IMF) by using a large sample of 24,781 early-type galaxies from the SDSS-based SPIDER survey. Clear…
Bottom-heavy initial mass function in a nearby compact L*-galaxy
Ronald Läsker, Remco C. E. van den Bosch, Glenn van de Ven +4
We present orbit-based dynamical models and stellar population analysis of galaxy SDSS J151741.75-004217.6, a low-redshift (z=0.116) early-type galaxy (ETG) which, for its moderate…
Age-dating the Tully-Fisher relation at moderate redshift
Ignacio Ferreras, Asmus Böhm, Bodo Ziegler +1
We analyse the Tully-Fisher relation at moderate redshift from the point of view of the underlying stellar populations, by comparing optical and NIR photometry with a phenomenologi…
