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…
VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
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…
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…
Analysis of Gaia Data Release 3 Parallax bias in the Galactic plane
Ye Ding, Shilong Liao, Qiqi Wu +2
The systematic errors are inevitable in Gaia published astrometric data. Lindegren et al. (L21) proposed a global recipe to correct for the GEDR3 parallax zero point offset, which…
