The stellar halo of isolated central galaxies in the Hyper Suprime-Cam imaging survey
Wenting Wang, Jiaxin Han, Alessandro Sonnenfeld +14
We study the faint stellar halo of isolated central galaxies, by stacking galaxy images in the HSC survey and accounting for the residual sky background sampled with random points.…
Testing Shear Recovery with Field Distortion
Jun Zhang, Fuyu Dong, Hekun Li +7
The tilt, rotation, or offset of each CCD with respect to the focal plane, as well as the distortion of the focal plane itself, cause shape distortions to the observed objects, an…
Fourier Power Function Shapelets (FPFS) Shear Estimator: Performance on Image Simulations
Xiangchong Li, Nobuhiko Katayama, Masamune Oguri +1
We reinterpret the shear estimator developed by Zhang & Komatsu (2011) within the framework of Shapelets and propose the Fourier Power Function Shapelets (FPFS) shear estimator. Fo…
