REVISING THE HALOFIT MODEL FOR THE NONLINEAR MATTER POWER SPECTRUM
Based on a suite of state-of-the-art high-resolution N-body simulations, we revisit the so-called halofit model as an accurate fitting formula for the nonlinear matter power spectrum. While the…

Gravitationally lensed quasars and supernovae in future wide-field optical imaging surveys
Cadenced optical imaging surveys in the next decade will be capable of detecting time-varying galaxy-scale strong gravitational lenses in large numbers, increasing the size of the statistically…

Clustering of High-Redshift (z ≥ 2.9) Quasars from the Sloan Digital Sky Survey
We study the two-point correlation function of a uniformly selected sample of 4426 luminous optical quasars with redshift 2.9 ≤ z ≤ 5.4 selected over 4041 deg2 from the Fifth Data Release of the…

LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic…

Combined strong and weak lensing analysis of 28 clusters from the Sloan Giant Arcs Survey
We study the mass distribution of a sample of 28 galaxy clusters using strong and weak lensing observations. The clusters are selected via their strong lensing properties as part of the Sloan Giant…

The Mass Distribution of SDSS J1004$+$4112 Revisited
We present a strong lens analysis of SDSS J1004+4112, a unique quasar lens produced by a massive cluster of galaxies at z = 0.68, using newly developed software for gravitational lensing. We find…

A gravitationally lensed quasar with quadruple images separated by 14.62 arcseconds
TLDR
The discovery of a lensed quasar, SDSS J1004 + 4112, which has a maximum separation between the components of 14.62 arcsec is reported, fully consistent with theoretical expectations based on the cold-dark-matter model.

DISCOVERY OF A GIANT Lyα EMITTER NEAR THE REIONIZATION EPOCH
We report the discovery of a giant Lyα emitter (LAE) with a Spitzer/Infrared Array Camera (IRAC) counterpart near the reionization epoch at z = 6.595. The giant LAE is found from the extensive 1 deg2…

Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137 deg2 of the sky. Thanks to the high effective galaxy number…

Binary Quasars in the Sloan Digital Sky Survey: Evidence for Excess Clustering on Small Scales
We present a sample of 221 new quasar pairs with proper transverse separations Rprop < 1 h-1 Mpc over the redshift range 0.5 < z < 3.0, discovered from an extensive follow-up campaign to find…
