Scalings between Physical and their Observationally related Quantities of Merger Remnants
H. Aceves, H. Velazquez
We present scaling relations between the virial velocity (V) and the one-dimensional central velocity dispersion (Sig0); the gravitational radius (Rv) and the effective radius (Re)…
Preservation of Cuspy Profiles in Disk Galaxy Mergers
Hector Aceves, Hector Velazquez
We carried out three self-consistent -body simulations of galaxy mergers, with a cuspy dark matter profile, in order to study if the inner dark density slope is preserved in the…
From Detailed Galaxy Simulations to a Realistic End-of-Mission Gaia Catalogue
Anthony Brown, Hector Velazquez, Luis Aguilar
We address the problem of identifying remnants of satellite galaxies in the halo of our galaxy with Gaia data. We make use of N-body simulations of dwarf galaxies being disrupted i…
N-Body Simulations of Small Galaxy Groups
Hector Aceves, Hector Velazquez
A series of N-body simulations aimed to study the dynamics of small groups of galaxies are presented. The properties of small galaxy groups are very well reproduced, and those of H…
