The Power Spectrum Dependence of Dark Matter Halo Concentrations
V. R. Eke, J. F. Navarro, M. Steinmetz
High-resolution N-body simulations are used to examine the power spectrum dependence of the concentration of galaxy-sized dark matter halos. It is found that dark halo concentratio…
Palomar 13's Last Stand
M. H. Siegel, S. R. Majewski, K. M. Cudworth +1
We present a proper motion and CCD photometric study of stars in the distant halo globular cluster Palomar 13. The absolute proper motion of Pal 13 with respect to the background g…
Exploring Halo Substructure with Giant Stars: I. Survey Description and Calibration of the Photometric Search Technique
Steven R. Majewski, James C. Ostheimer, William E. Kunkel +1
We have begun a survey of the structure of the Milky Way halo, as well as the halos of other Local Group galaxies, as traced by their constituent giant stars. These giant stars are…
The Absolute Proper Motion of Palomar 12: A Case for Tidal Capture from the Sagittarius Dwarf Spheroidal Galaxy
D. I. Dinescu, S. R. Majewski, T. M. Girard +1
We have measured the absolute proper motion of the young globular cluster Pal 12 with respect to background galaxies, using plate material spanning a 40-year time baseline, and mea…
Exploring the Leo II dSph I.: The Variable Star Content
M. H. Siegel, S. R. Majewski
We present the first comprehensive catalogue of variable stars in the Leo II dwarf spheroidal galaxy. We have identified 148 RR Lyrae type variables, of which 140 were amenable to…
Multiwavelength Observations of the Second Largest Known FR II Radio Galaxy, NVSS 2146+82
Christopher Palma, Franz E. Bauer, William D. Cotton +3
We present multi-frequency VLA, multicolor CCD imaging, optical spectroscopy, and ROSAT HRI observations of the giant FR II radio galaxy NVSS 2146+82. This galaxy, which was discov…
