Dynamics of the galactic component of Abell S1063 and MACS J1206.20847
Giovanni Ferrami, Giuseppe Bertin, Claudio Grillo +2
The galactic component in clusters is commonly thought to be generally nonrotating and in a dynamical state different from that of a collisionally relaxed system. In practice, a te…
Direct Measurements of the magnification produced by galaxy clusters as gravitational lenses
Alessandro Sonnenfeld, Giuseppe Bertin, Marco Lombardi
Weak lensing is one of the best available diagnostic tools to measure the total density profiles of distant clusters of galaxies. Unfortunately, it suffers from the well-known mass…
Prominent spiral arms in the gaseous outer galaxy disks
G. Bertin, N. C. Amorisco
Context: Several spiral galaxies, as beautifully exhibited by the case of NGC 6946, display a prominent large-scale spiral structure in their gaseous outer disk. Such structure is…
