Reconciling concentration to virial mass relations
Dominik Leier, Ignacio Ferreras, Andrea Negri +1
The concentration-virial mass (c-M) relation is a fundamental scaling relation within the standard cold dark matter (CDM) framework well established in numerical simulations. Ho…
Observed versus Simulated Halo c-Mvir Relations
Dominik Leier, Ignacio Ferreras, Andrea Negri +1
The concentration - virial mass relation is a well-defined trend that reflects the formation of structure in an expanding Universe. Numerical simulations reveal a marked correlatio…
The lens SW05 J143454.4+522850: a fossil group at redshift 0.6?
Philipp Denzel, Onur Çatmabacak, Jonathan P. Coles +8
Fossil groups are considered the end product of natural galaxy group evolution in which group members sink towards the centre of the gravitational potential due to dynamical fricti…
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…
Resolving the baryon-fraction profile in lensing galaxies
Dominik Leier, Ignacio Ferreras, Prasenjit Saha +1
We show the radial dependence of stellar baryon fraction curves derived for 21 lensing galaxies from the CfA-Arizona Space Telescope LEns Survey by means of stellar population synt…
