On the density profile of dark matter substructure in gravitational lens galaxies
Simona Vegetti, Mark Vogelsberger
We consider three extensions of the Navarro, Frenk and White (NFW) profile and investigate the intrinsic degeneracies among the density profile parameters on the gravitational lens…
3C 220.3: a radio galaxy lensing a submillimeter galaxy
Martin Haas, Christian Leipski, Peter Barthel +17
Herschel Space Observatory photometry and extensive multiwavelength followup have revealed that the powerful radio galaxy 3C 220.3 at z=0.685 acts as a gravitational lens for a bac…
Inference of the Cold Dark Matter substructure mass function at z=0.2 using strong gravitational lenses
S. Vegetti, L. V. E. Koopmans, M. W. Auger +2
We present the results of a search for galaxy substructures in a sample of 11 gravitational lens galaxies from the Sloan Lens ACS Survey. We find no significant detection of mass c…
Lensing Model of MACS J1149.5+2223 - I. Cluster mass reconstruction
Stefan Rau, Simona Vegetti, Simon D. M. White
Measurements of the total logarithmic central slope of the mass profile in galaxy clusters constrain their evolution and assembly history and that of their brightest cluster galaxi…
