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...
Faint NUV/FUV Standards from Swift/UVOT, GALEX and SDSS Photometry
Faint NUV/FUV Standards Swift/UVOT GALEX SDSS Photometry
2011/1/11
At present, the precision of deep ultraviolet photometry is somewhat limited by the dearth of faint ultraviolet standard stars. In an effort to improve this situation, we present a uniform catalog of ...
Probing the faint end of the quasar luminosity function at z ~ 4 in the COSMOS field
cosmology observations — quasars general — surveys
2010/11/12
We searched for quasars that are 3 mag fainter than the SDSS quasars in the redshift range 3.7 . z . 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity function.
The radio properties of infrared-faint radio sources
Galaxies active Galaxies high-redshift
2010/11/15
Context. Infrared-faint radio sources (IFRS) are objects that have flux densities of several mJy at 1.4 GHz, but that are invisible at 3.6 m when using sensitive Spitzer observations with Jy sensiti...
Faint dwarf galaxies in the Next Generation Virgo cluster Survey
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
The Next Generation Virgo Cluster Survey (NGVS) is a CFHT Large Program that is using the wide field of view capabilities of the MegaCam camera to map the entire Virgo Cluster from its core to virial ...
Faint dwarf galaxies in nearby clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
Besides giant elliptical galaxies, a number of low-mass stellar systems inhabit the cores of galaxy clusters, such as dwarf elliptical galaxies (dEs/dSphs), ultra-compact dwarf galaxies (UCDs), and gl...
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...
