Scientific Synergy Between LSST and Euclid
Jason Rhodes, Robert C. Nichol, Éric Aubourg +34
Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high cadence, deep, wid…
Weak lensing for precision cosmology
Rachel Mandelbaum
Weak gravitational lensing, the deflection of light by mass, is one of the best tools to constrain the growth of cosmic structure with time and reveal the nature of dark energy. I…
Weak lensing shear calibration with simulations of the HSC survey
Rachel Mandelbaum, François Lanusse, Alexie Leauthaud +8
We present results from a set of simulations designed to constrain the weak lensing shear calibration for the Hyper Suprime-Cam (HSC) survey. These simulations include HSC observin…
First results on the cluster galaxy population from the Subaru Hyper Suprime-Cam survey. II. Faint end color-magnitude diagrams and radial profiles of red and blue galaxies at
Atsushi J. Nishizawa, Masamue Oguri, Taira Oogi +16
We present a statistical study of the redshift evolution of the cluster galaxy population over a wide redshift range from 0.1 to 1.1, using optically-selected CAMIRA cl…
DESCQA: An Automated Validation Framework for Synthetic Sky Catalogs
Yao-Yuan Mao, Eve Kovacs, Katrin Heitmann +24
The use of high-quality simulated sky catalogs is essential for the success of cosmological surveys. The catalogs have diverse applications, such as investigating signatures of fun…
Two- and three-dimensional wide-field weak lensing mass maps from the Hyper Suprime-Cam Subaru Strategic Program S16A data
Masamune Oguri, Satoshi Miyazaki, Chiaki Hikage +12
We present wide-field (167 deg) weak lensing mass maps from the Hyper Supreme-Cam Subaru Strategic Program (HSC-SSP). We compare these weak lensing based dark matter maps with…
