Sersic Properties of Disc Galaxy Mergers
H. Aceves, H. Velazquez, F. Cruz
Sersic parameters characterising the density profiles of remnants formed in collision-less disc galaxy mergers are obtained; no bulge is included in our simulations. For the lumino…
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…
Detection of satellite remnants in the Galactic Halo with Gaia - I. The effect of the Galactic background, observational errors and sampling
Anthony Brown, Hector Velazquez, Luis Aguilar +1
We address the problem of identifying remnants of satellite galaxies in the halo of our galaxy with Gaia data. The remnants have to be extracted from a very large data set (of orde…
From the Tully-Fisher relation to the Fundamental Plane through Mergers
Hector Aceves, Hector Velazquez
We set up a series of self-consistent N-body simulations to investigate the fundamental plane of merger remnants of spiral galaxies. These last ones are obtained from a theoretical…
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…
