Cosmological Studies from HSC-SSP Tomographic Weak Lensing Peak Abundances
Xiangkun Liu, Shuo Yuan, Chuzhong Pan +3
We perform weak lensing tomographic peak studies using the first-year shear data from Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey. The effective area used in our an…
Effects of galaxy intrinsic alignment on weak lensing peak statistics
Tianyu Zhang, Xiangkun Liu, Chengliang Wei +4
The galaxy intrinsic alignment (IA) is a dominant source of systematics in weak lensing (WL) studies. In this paper, by employing large simulations with semi-analytical galaxy form…
Dark Matter Halos in Interacting Dark Energy Models: Formation History, Density Profile, Spin and Shape
Yun Liu, Shihong Liao, Xiangkun Liu +3
The interacting dark energy (IDE) model, which considers the interaction between dark energy and dark matter, provides a natural mechanism to alleviate the coincidence problem and…
Detection of Cosmic Magnification via Galaxy Shear -- Galaxy Number Density Correlation from HSC Survey Data
Xiangkun Liu, Dezi Liu, Zucheng Gao +5
We propose a novel method to detect cosmic magnification signals by cross-correlating foreground convergence fields constructed from galaxy shear measurements with background galax…
Deep Learning for Strong Lensing Search: Tests of the Convolutional Neural Networks and New Candidates from KiDS DR3
Zizhao He, Xinzhong Er, Qian Long +6
Convolutional Neutral Networks have been successfully applied in searching for strong lensing systems, leading to discoveries of new candidates from large surveys. On the other han…
Astronomical Site Monitoring System at Lijiang Observatory
Yu-Xin Xin, Jin-Ming Bai, Bao-Li Lun +18
We installed two sets of Astronomical Site Monitoring System(ASMS) at Lijiang Observatory(GMG), for the running of the 2.4-meter Lijiang optical telescope(LJT) and the 1.6-meter Mu…
