Modeling Tidal Streams in evolving dark matter halos
Jorge Penarrubia, Andrew J. Benson, David Martinez-Delgado +1
We explore whether stellar tidal streams can provide information on the secular, cosmological evolution of the Milky Way's gravitational potential and on the presence of subhalos.…
Absolute Proper Motion of the Canis Major Dwarf Galaxy Candidate
Dana I. Dinescu, David Martinez-Delgado, Terrence M. Girard +4
We have measured the absolute proper motion of the candidate Canis Major dwarf galaxy (CMa) at $(l,b) = (240\arcdeg, -8\arcdeg)$. Likely main-sequence stars in CMa have been select…
The Canis Major dwarf galaxy as the progenitor of the Monoceros tidal stream
David Martinez-Delgado, Jorge Penarrubia, D. I. Dinescu +2
The Sloan Digital Sky Survey has recently discovered a coherent ring of stars at low galactic latitude that is believed to be the tidal stream of a merging dwarf galaxy in the Gala…
On the kinematics of the neutron star low mass X-ray binary Cen X-4
J. I. González Hernández, R. Rebolo, J. Peñarrubia +2
We present the first determination of the proper motion of the neutron star low mass X-ray binary {Cen X-4} measured from relative astrometry of the secondary star using optical im…
