J/ApJ/598/260          Satellites orbiting isolated galaxies      (Prada+, 2003)

Observing the dark matter density profile of isolated galaxies. Prada F., Vitvitska M., Klypin A., Holtzman J.A., Schlegel D.J., Grebel E.K., Rix H.-W., Brinkmann J., Mckay T.A., Csabai I. <Astrophys. J., 598, 260-271 (2003)> =2003ApJ...598..260P
ADC_Keywords: Galaxies, photometry ; Radial velocities Keywords: dark matter - galaxies: dwarf - galaxies: halos - galaxies: kinematics and dynamics - surveys Abstract: Using the Sloan Digital Sky Survey (SDSS), we probe the halo mass distribution by studying the velocities of satellites orbiting isolated galaxies. In a subsample that covers 2500°2 on the sky, we detect about 3000 satellites with absolute blue magnitudes going down to MB=-14; most of the satellites have MB=-16 to -18, comparable to the magnitudes of M32 and the Magellanic Clouds. Description: For the current analysis, we use data on galaxies for which spectra were obtained before 2002 August. File Summary:
