FPFS Shear Estimator: Systematic Tests on the Hyper Suprime-Cam Survey First Year Data
Xiangchong Li, Masamune Oguri, Nobuhiko Katayama +6
We apply the Fourier Power Function Shapelets (FPFS) shear estimator to the first year data of the Hyper Suprime-Cam survey to construct a shape catalog. The FPFS shear estimator h…
New test on general relativity and torsional gravity from galaxy-galaxy weak lensing surveys
Zhaoting Chen, Wentao Luo, Yi-Fu Cai +1
We use galaxy-galaxy weak lensing data to perform a novel test on general relativity (GR) and torsional gravity. In particular, we impose strong constraints using the torsio…
New perspectives on the BOSS small-scale lensing discrepancy for the Planck CDM Cosmology
Johannes U. Lange, Xiaohu Yang, Hong Guo +2
We investigate the abundance, small-scale clustering and galaxy-galaxy lensing signal of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS). To this end, we present new…
Towards a Model-Independent Measurement of the Halo Mass Function with Observables
Fuyu Dong, Jun Zhang, Xiaohu Yang +2
In the CDM paradigm, the halo mass function is a sensitive probe of the cosmic structure. In observations, halo mass is typically estimated from its relation with other observables…
Second Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +62
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru Telescope. The release in…
