The Pre-explosion Environments and The Progenitor of SN 2023ixf from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX)
Chenxu Liu, Xinlei Chen, Xinzhong Er +20
Supernova (SN) 2023ixf was discovered on May 19th, 2023. The host galaxy, M101, was observed by the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) collaboration over the pe…
A 12.4 day periodicity in a close binary system after a supernova
Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37
Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…
Weak lensing peak statistics -- steepness versus height
Ziwei Li, Xiangkun Liu, Zuhui Fan
In weak-lensing cosmological studies, peak statistics is sensitive to nonlinear structures and thus complementary to cosmic shear two-point correlations. In this paper, we explore…
Constraining Gravity Theory Using Weak Lensing Peak Statistics from the Canada-France-Hawaii-Telescope Lensing Survey
Xiangkun Liu, Baojiu Li, Gong-Bo Zhao +8
In this Letter, we report the observational constraints on the Hu-Sawicki theory derived from weak lensing peak abundances, which are closely related to the mass function of…
Galaxy-Galaxy Weak Lensing Measurements from SDSS: I. Image Processing and Lensing signals
Wentao Luo, Xiaohu Yang, Jun Zhang +11
As the first paper in a series on the study of the galaxy-galaxy lensing from Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our image processing pipeline that corr…
Cosmological Constraints From Weak Lensing Peak Statistics With CFHT Stripe 82 Survey
Xiangkun Liu, Chuzhong Pan, Ran Li +11
We derived constraints on cosmological parameters using weak lensing peak statistics measured on the of the Canada-France-Hawaii Telescope Stripe 82 Survey (C…
