An Alternative Origin for Hypervelocity Stars
Mario G. Abadi, Julio F. Navarro, Matthias Steinmetz
Halo stars with unusually high radial velocity ("hypervelocity" stars, or HVS) are thought to be stars unbound to the Milky Way that originate from the gravitational interaction of…
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…
Satellites of Simulated Galaxies: survival, merging, and their relation to the dark and stellar halos
L. V. Sales, J. F. Navarro, M. G. Abadi +1
We study the population of satellite galaxies formed in a suite of N-body/gasdynamical simulations of galaxy formation in a LCDM universe. We find little spatial or kinematic bias…
Stars beyond Galaxies: The Origin of Extended Luminous Halos around Galaxies
Mario G. Abadi, Julio F. Navarro, Matthias Steinmetz
(Abridged) We use numerical simulations to investigate the origin and structure of the luminous halos that surround isolated galaxies. These stellar structures extend out to severa…
Pieces of the puzzle: Ancient substructure in the Galactic disk
Amina Helmi, J. F. Navarro, B. Nordstrom +3
We search for signatures of past accretion events in the Milky Way in the recently published catalogue by Nordstrom et al.(2004), containing accurate spatial and kinematic informat…
Accretion relicts in the solar neighbourhood: debris from omegaCen's parent galaxy
Andres Meza, Julio F. Navarro, Mario G. Abadi +1
We use numerical simulations to investigate the orbital characteristics of tidal debris from satellites whose orbits are dragged into the plane of galactic disks by dynamical frict…
