Strong Gravitational Lensing and the Stellar IMF of Early-type Galaxies
Dominik Leier, Ignacio Ferreras, Prasenjit Saha +3
Systematic variations of the IMF in early-type galaxies, and their connection with possible drivers such as velocity dispersion or metallicity, have been much debated in recent yea…
Radial constraints on the Initial Mass Function from TiO features and Wing-Ford band in Early-type Galaxies
F. La Barbera, A. Vazdekis, I. Ferreras +5
At present, the main challenge to the interpretation of variations in gravity-sensitive line strengths as driven by a non-universal initial mass function (IMF), lies in understandi…
The first and second data releases of the Kilo-Degree Survey
Jelte T. A. de Jong, Gijs A. Verdoes Kleijn, Danny R. Boxhoorn +46
The Kilo-Degree Survey (KiDS) is an optical wide-field imaging survey carried out with the VLT Survey Telescope and the OmegaCAM camera. KiDS will image 1500 square degrees in four…
First discoveries of z~6 quasars with the Kilo Degree Survey and VISTA Kilo-Degree Infrared Galaxy survey
B. P. Venemans, G. A. Verdoes Kleijn, J. Mwebaze +12
We present the results of our first year of quasar search in the on-going ESO public Kilo Degree Survey (KiDS) and VISTA Kilo-Degree Infrared Galaxy (VIKING) surveys. These surveys…
IMF - metallicity: a tight local relation revealed by the CALIFA survey
Ignacio Martín-Navarro, Alexandre Vazdekis, Francesco La Barbera +13
Variations in the stellar initial mass function (IMF) have been invoked to explain the spectroscopic and dynamical properties of early-type galaxies. However, no observations have…
Further evidence for a time-dependent initial mass function in massive early-type galaxies
I. Ferreras, C. Weidner, A. Vazdekis +1
Spectroscopic analyses of gravity-sensitive line strengths give growing evidence towards an excess of low-mass stars in massive early-type galaxies (ETGs). Such a scenario requires…
