Near-Infrared Imaging Survey of Faint Companions around Young Dwarfs in the Pleiades Cluster
Near-Infrared Imaging Survey Faint Companions around Young Dwarfs
2011/1/10
We conducted a near-infrared imaging survey of 11 young dwarfs in the Pleiades cluster using the Subaru Telescope and the near-infrared coronagraph imager. We found 10 faint point sources, with magnit...
We develop a technique to investigate the possibility that some of the recently discovered ultra-faint dwarf satellites of the Milky Way might be cusp caustics rather than gravitationally self-bound s...
Understanding the faint red galaxy population using large-scale clustering measurements from SDSS DR7
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We use data from the SDSS to investigate the evolution of the large-scale galaxy bias as a function of luminosity for red galaxies. We carefully consider correlation functions of galaxies selected fro...
