HybPSF: Hybrid PSF reconstruction for the observed JWST NIRCam image
Lin Nie, Huanyuan Shan, Guoliang Li +6
The James Webb Space Telescope (JWST) ushers in a new era of astronomical observation and discovery, offering unprecedented precision in a variety of measurements such as photometr…
The spherical Fast Multipole Method (sFMM) for Gravitational Lensing Simulation
Xingpao Suo, Xi Kang, Chengliang Wei +1
In this paper, we present a spherical Fast Multipole Method (sFMM) for ray tracing simulation of gravitational lensing (GL) on a curved sky. The sFMM is a non-trivial extension of…
Towards Super-resolution via Iterative multi-exposure Coaddition
Lei Wang, Guoliang Li, Xi Kang
In this article, we provide an alternative up-sampling and PSF deconvolution method for the iterative multi-exposure coaddition. Different from the previous works, the new method h…
An Improved GPU-Based Ray-Shooting Code For Gravitational Microlensing
Wenwen Zheng, Xuechun Chen, Guoliang Li +1
We present an improved inverse ray-shooting code based on GPUs for generating microlensing magnification maps. In addition to introducing GPUs for acceleration, we put the efforts…
An accurate centroid algorithm for PSF reconstruction
Tianhuan Lu, Wentao Luo, Jun Zhang +8
In this work, we present a novel centroiding method based on Fourier space Phase Fitting(FPF) for Point Spread Function(PSF) reconstruction. We generate two sets of simulations to…
The Point Spread Function Reconstruction by Using Moffatlets - I
Baishun Li, Guoliang Li, Jun Cheng +2
The shear measurement is a crucial task in the current and the future weak lensing survey projects. And the reconstruction of the point spread function(PSF) is one of the essential…
