GRB 211227A as a peculiar long gamma-ray burst from compact star merger
Hou-Jun Lü, Hao-Yu Yuan, Ting-Feng Yi +16
Long-duration gamma-ray bursts (GRBs) associated with supernovae (SNe) are believed to originate from massive star core-collapse events, whereas short-duration GRBs that are relate…
Astronomical Site Monitoring System at Lijiang Observatory
Yu-Xin Xin, Jin-Ming Bai, Bao-Li Lun +18
We installed two sets of Astronomical Site Monitoring System(ASMS) at Lijiang Observatory(GMG), for the running of the 2.4-meter Lijiang optical telescope(LJT) and the 1.6-meter Mu…
Active Galactic Nuclei with Ultra-fast Outflows Monitoring Project: The Broad-line Region of Mrk 79 as a Disk Wind
Kai-Xing Lu, Jin-Ming Bai, Zhi-Xiang Zhang +23
We developed a spectroscopic monitoring project to investigate the kinematics of the broad-line region (BLR) in active galactic nuclei (AGN) with ultra-fast outflows (UFOs). Mrk~79…
Extremely luminous optical afterglow of an energetic gamma-ray burst GRB 230204B
Rahul Gupta, Judith Racusin, Vladimir Lipunov +47
Robotic telescope networks play an important role in capturing early and bright optical afterglows, providing critical insights into the energetics and emission mechanisms of GRBs.…
Lijiang 2.4-meter Telescope and its Instruments
Chuan-Jun Wang, Jin-Ming Bai, Yu-Feng Fan +32
Lijiang 2.4-meter Telescope(LJT), the largest common-purpose optical telescope in China, has been applied to the world-wide astronomers since 2008. It is located at Gaomeigu site,…
SDSS J013127.34032100.1: A newly discovered radio-loud quasar at with extremely high luminosity
Wei-Min Yi, Feige Wang, Xue-Bing Wu +18
Only very few z>5 quasars discovered to date are radio-loud, with a radio-to-optical flux ratio (radio-loudness parameter) higher than 10. Here we report the discovery of an optica…
The physical constraints on a new LoBAL QSO at z=4.82
Weimin Yi, Richard Green, Jin-Ming Bai +26
Very few low-ionization broad absorption line (LoBAL) QSOs have been found at high redshifts to date. One high-redshift LoBAL QSO, J0122+1216, was recently discovered at the Lijian…
