Information content of weak lensing power spectrum and bispectrum: including the non-Gaussian error covariance matrix
Issha Kayo, Masahiro Takada, Bhuvnesh Jain
We address the amount of information in the non-Gaussian regime of weak lensing surveys by modelling all relevant covariances of the power spectra and bispectra, using 1000 ray-tra…
The quasar-galaxy cross SDSS J1320+1644: A probable large-separation lensed quasar
Cristian E. Rusu, Masamune Oguri, Masanori Iye +5
We report the discovery of a pair of quasars at , with a separation of $8\farcs585\pm0\farcs002$. Subaru Telescope infrared imaging reveals the presence of an elliptical a…
The Sloan Digital Sky Survey Quasar Lens Search. VI. Constraints on Dark Energy and the Evolution of Massive Galaxies
Masamune Oguri, Naohisa Inada, Michael A. Strauss +12
We present a statistical analysis of the final lens sample from the Sloan Digital Sky Survey Quasar Lens Search (SQLS). The number distribution of a complete subsample of 19 lensed…
The Sloan Digital Sky Survey Quasar Lens Search. V. Final Catalog from the Seventh Data Release
Naohisa Inada, Masamune Oguri, Min-Su Shin +13
We present the final statistical sample of lensed quasars from the Sloan Digital Sky Survey (SDSS) Quasar Lens Search (SQLS). The well-defined statistical lens sample consists of 2…
Very small-scale clustering of quasars from a complete quasar lens survey
Issha Kayo, Masamune Oguri
We measure the small-scale (comoving separation 10 kpc/h < r_p < 200 kpc/h) two-point correlation function of quasars using a sample of 26 spectroscopically confirmed binary quasar…
