On the genealogy of the Orphan Stream
L. V. Sales, A. Helmi, E. Starkenburg +6
We use N-body simulations to explore the origin and a plausible orbit for the Orphan Stream, one of the faintest substructures discovered so far in the outer halo of our Galaxy. We…
Satellite Galaxies and Fossil Groups in the Millennium Simulation
L. V. Sales, J. F. Navarro, D. G. Lambas +2
We use a semianalytic galaxy catalogue constructed from the Millennium Simulation to study the satellites of isolated galaxies in the LCDM cosmogony. This sample (~80,000$ bright p…
Cosmic Ménage à Trois: The Origin of Satellite Galaxies On Extreme Orbits
L. V. Sales, J. F. Navarro, M. G. Abadi +1
We examine the orbits of satellite galaxies identified in a suite of N-body/gasdynamical simulations of the formation of galaxies in a LCDM universe. Most satellites follow c…
Satellite number density profiles of primary galaxies in the 2dFGRS
Laura Sales, Diego G. Lambas
We analyse the projected radial distribution of satellites around bright primary galaxies in the 2dFGRS. We have considered several primary-satellite subsamples to search for depen…
Anisotropy in the distribution of satellites around primary galaxies in the 2dFGRS: the Holmberg effect
Laura Sales, Diego G. Lambas
We have analysed a sample of satellite and primary galaxies in the 2dF galaxy redshift survey. In our study we find a strong statistical evidence of the Holmberg effect (that is a…
