Differencing and Coadding JWST Images with Matched Point Spread Function
Lei Hu, Lifan Wang
We present an algorithm to derive difference images for data taken with the JWST with matched point-spread functions (PSFs). It is based on the saccadic fast Fourier transform (SFF…
Deep Drilling in the Time Domain with DECam: Survey Characterization
Melissa L. Graham, Robert A. Knop, Thomas Kennedy +41
This paper presents a new optical imaging survey of four deep drilling fields (DDFs), two Galactic and two extragalactic, with the Dark Energy Camera (DECam) on the 4 meter Blanco…
Antarctic Survey Telescope 3-3: Overview, System Performance and Preliminary Observations at Yaoan, Yunnan
Tianrui Sun, Xiaoyan Li, Lei Hu +17
The third Antarctic Survey Telescope array instrument at Dome A in Antarctica, the AST3-3 telescope, has been in commissioning from March 2021. We deployed AST3-3 at the Yaoan astr…
Pipeline for Antarctic Survey Telescope 3-3 in Yaoan, Yunnan
Tianrui Sun, Lei Hu, Songbo Zhang +5
AST3-3 is the third robotic facility of the Antarctic Survey Telescopes (AST3) for transient surveys to be deployed at Dome A, Antarctica. Due to the current pandemic, the telescop…
Image Subtraction in Fourier Space
Lei Hu, Lifan Wang, Xingzhuo Chen +1
Image subtraction is essential for transient detection in time-domain astronomy. The point spread function (PSF), photometric scaling, and sky background generally vary with time a…
The Tsinghua University-Ma Huateng Telescopes for Survey: Overview and Performance of the System
Ji-Cheng Zhang, Xiao-Feng Wang, Jun Mo +16
Over the past decade, time-domain astronomy in optical bands has developed rapidly with the operations of some wide-field survey facilities. However, most of these surveys are cond…
