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…
Light versus dark in strong-lens galaxies: Dark matter haloes that are rounder than their stars
Claudio Bruderer, Justin I. Read, Jonathan P. Coles +4
We measure the projected density profile, shape and alignment of the stellar and dark matter mass distribution in 11 strong-lens galaxies. We find that the projected dark matter de…
Systematic variation of central mass density slope in early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano +3
We study the total density distribution in the central regions ( effective radius, ) of early-type galaxies (ETGs), using data from the SPIDER survey. We model ea…
Variations of the dust properties of M82 with galactocentric distance
S. Hutton, I. Ferreras, V. Yershov
We use near ultraviolet and optical photometry to investigate the dust properties in the nearby starburst galaxy M82. By combining imaging from the Swift/UVOT instrument and optica…
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…
The Initial Mass Function of Early-type Galaxies: no correlation with [Mg/Fe]
F. La Barbera, I. Ferreras, A. Vazdekis
The Initial Mass Function (IMF) of early-type galaxies (ETGs) has been found to feature systematic variations by both dynamical and spectroscopic studies. In particular, spectral l…
