CSST Strong Lensing Preparation: a Framework for Detecting Strong Lenses in the Multi-color Imaging Survey by the China Survey Space Telescope (CSST)
Xu Li, Ruiqi Sun, Jiameng Lv +29
Strong gravitational lensing is a powerful tool for investigating dark matter and dark energy properties. With the advent of large-scale sky surveys, we can discover strong lensing…
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…
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…
Tolerance For the Pixelation Effect in Shear Measurement
Zhi Shen, Jun Zhang, Hekun Li +6
Images taken by space telescopes typically have a superb spatial resolution, but a relatively poor sampling rate due to the finite CCD pixel size. Beyond the Nyquist limit, it beco…
