UPdec-Webb: A Dataset for Coaddition of JWST NIRCam Images
Lei Wang, Huanyuan Shan, Lin Nie +19
We present the application of the image coaddition algorithm, Up-sampling and PSF Deconvolution Coaddition (UPDC), for stacking multiple exposure images captured by the James Webb…
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…
How to coadd images: II. Anti-aliasing and PSF deconvolution
Lei Wang, Huanyuan Shan, Lin Nie +8
We have developed a novel method for co-adding multiple under-sampled images that combines the iteratively reweighted least squares and divide-and-conquer algorithms. Our approach…
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…
Variability and transient search in the SUDARE-VOICE field: a new method to extract the light curves
Dezi Liu, Wenqiang Deng, Zuhui Fan +12
The VST Optical Imaging of the CDFS and ES1 Fields (VOICE) Survey, in synergy with the SUDARE survey, is a deep optical imaging of the CDFS and ES1 fields using the VLT Surv…
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…
Testing photometric redshift measurements with filter definition of the Chinese Space Station Optical Survey (CSS-OS)
Ye Cao, Yan Gong, Xian-Min Meng +11
The Chinese Space Station Optical Survey (CSS-OS) is a major science project of the Space Application System of the China Manned Space Program. This survey is planned to perform bo…
