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…
SPIDER IX - Classifying Galaxy Groups according to their Velocity Distribution
A. L. B. Ribeiro, A. C. Schilling, R. R. de Carvalho +4
We introduce a new method to study the velocity distribution of galaxy systems, the Hellinger Distance (HD) - designed for detecting departures from a Gaussian velocity distributio…
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…
