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…
Galaxy Light profile neural Networks (GaLNets). II. Bulge-Disc decomposition in optical space-based observations
Chen Qiu, Nicola R. Napolitano, Rui Li +12
Bulge-disk (B-D) decomposition is an effective diagnostic to characterize the galaxy morphology and understand its evolution across time. So far, high-quality data have allowed det…
The chromatic Point Spread Function of weak lensing measurement in Chinese Space Station survey Telescope
Q. Y. Liu, X. Z. Er, Z. H. Fan +6
The weak gravitational lensing is a powerful tool in modern cosmology. To accurately measure the weak lensing signal, one has to control the systematic bias to a small level. One o…
CSST WL preparation I: forecast the impact from non-Gaussian covariances and requirements on systematics-control
Ji Yao, Huanyuan Shan, Ran Li +11
The precise estimation of the statistical errors and accurate removal of the systematical errors are the two major challenges for the stage IV cosmic shear surveys. We explore thei…
Forklens: Accurate weak-lensing shear measurement with deep learning
Zekang Zhang, Huanyuan Shan, Nan Li +25
Weak gravitational lensing is one of the most important probes of the nature of dark matter and dark energy. In order to extract cosmological information from next-generation weak…
