A Bayesian approach to strong lensing modelling of galaxy clusters
Eric Jullo, Jean-Paul Kneib, Marceau Limousin +3
In this paper, we describe a procedure for modelling strong lensing galaxy clusters with parametric methods, and to rank models quantitatively using the Bayesian evidence. We use a…
MS 2053.7-0449: Confirmation of a bimodal mass distribution from strong gravitational lensing
T. Verdugo, J. A. de Diego, M. Limousin
We present the first strong lensing study of the mass distribution in the cluster MS 2053-04 based on HST archive data. This massive, X-ray luminous cluster has a redshift z=0.583,…
A Multiwavelength study of NLS1s galaxies from the Second Byurakan Survey
J. A. Stepanian, E. Benitez, Y. Krongold +6
In this work we present a multiwavelength study of narrow-line Seyfert 1 galaxies (NLS1s) discovered in the Second Byurakan Survey (SBS). The sample consists of 26 objects, which h…
