Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112
M. Oguri, N. Inada, C. R. Keeton +25
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62…
A Catalog of Compact Groups of Galaxies in the SDSS Commissioning Data
B. C. Lee, S. S. Allam, D. L. Tucker +20
Compact groups (CGs) of galaxies -- relatively poor groups of galaxies in which the typical separations between members is of the order of a galaxy diameter -- offer an exceptional…
A Gravitationally Lensed Quasar with Quadruple Images Separated by 14.62 Arcseconds
N. Inada, M. Oguri, B. Pindor +29
Gravitational lensing is a powerful tool for the study of the distribution of dark matter in the Universe. The cold-dark-matter model of the formation of large-scale structures pre…
SDSS J115517.35+634622.0: A Newly Discovered Gravitationally Lensed Quasar
Bart Pindor, Daniel J. Eisenstein, Naohisa Inada +12
We report the discovery of SDSSJ115517.35+634622.0, a previously unknown gravitationally lensed quasar. The lens system exhibits two images of a quasar, with an image se…
SDSS J1335+0118: A New Two-Image Gravitational Lens
Masamune Oguri, Naohisa Inada, Francisco J. Castander +13
We report the discovery of the two-image gravitationally lensed quasar SDSS J1335+0118. The object was selected as a lens candidate from the Sloan Digital Sky Survey. The imaging a…
The 3D power spectrum of galaxies from the SDSS
M Tegmark, M Blanton, M Strauss +32
We measure the large-scale real-space power spectrum P(k) using a sample of 205,443 galaxies from the Sloan Digital Sky Survey, covering 2417 square degrees with mean redshift z~0.…
