Distribution functions for a family of axially symmetric galaxy models
, 2016 We present the derivation of distribution functions for the first four members of a family of disks, previously obtained in (MNRAS, 371, 1873, 2006), which represent a family of axially symmetric galaxy models with finite radius and well behaved surface ...

Effects of mergers and galaxy interactions at intermediate densities in the SDSS-DR4 [PDF]
, 2009 Recently, several observational works have provided evidence in favor of a pre-processing of galaxies at moderate environments. These evidences show that the transition of galaxies onto the red-sequence could take place in galaxy groups in the outskirt ...
