2MASS Re-processing I: The Search for Faint Objects
Zehao Liu, Xiyan Peng, Zhenghong Tang +3
We present an automated, DAOFind-based pipeline developed to reprocess J-band Atlas All Sky Release Survey Images from the Two Micron All Sky Survey (2MASS). By optimizing the dete…
Characterizing the astrometric quality of AGNs in Gaia-CRF3
Shilong Liao, Qiqi Wu, Ye Ding +2
Active Galactic Nuclei (AGNs), owing to their great distances and compact sizes, serve as fundamental anchors for defining the celestial reference frame. With about 1.9 million AGN…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Qian-Yu An, Yang Huang, Wei-Min Gu +21
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitatio…
Analysis of the Gaia Data Release 3 parallax bias at bright magnitudes
Ye Ding, Shilong Liao, Shangyu Wen +1
The combination of visual and spectroscopic orbits in binary systems enables precise distance measurements without additional assumptions, making them ideal for examining the paral…
DULAG: A DUal and Lensed AGN candidate catalog with GMP method
Qiqi Wu, M. Scialpi, Shilong Liao +2
Context. A series of studies have demonstrated that the Gaia multipeak method (GMP) is a very efficient technique to select active galactic nucleus (AGN) pair candidates. The numbe…
