The atmospheric extinction curve at Lenghu site
Jin-Sheng Qiu, Xiao-Hui Xu, Qing-Feng Zhu +11
In this study, we use a dedicated spectroscopic telescope to carry out low-resolution measurements of the optical atmospheric extinction curve at Lenghu astronomical site in Qingha…
The -ray-emitting blazar B3 1239+376 at = 3.82 identified in a multi-wavelength context
Wei Zhang, Neng-Hui Liao, Hao-Yi Huang +6
Among thousands of extragalactic -ray emitters, only a handful of distant ( 3) sources are detected. Yet, they are crucial probes shedding light on the cosmic evolution of…
A Star's Death by a Thousand Cuts: The Runaway Periodic Eruptions of AT2023uqm
Yibo Wang, Tingui Wang, Shifeng Huang +37
Stars on bound orbits around a supermassive black hole may undergo repeated partial tidal disruption events (rpTDEs), producing periodic flares. While several candidates have been…
Awakening of A Blazar at Redshift 2.7 Temporally Coincident with Arrival of Cospatial Neutrino Event IceCube-201221A
Xiong Jiang, Neng-Hui Liao, Yi-Bo Wang +3
We report on multiwavelength studies of a blazar NVSS J171822+423948, which is identified as the low-energy counterpart of 4FGL J1718.5+4237, the unique -ray source known to be…
ASASSN-18ap: A Dusty Tidal Disruption Event Candidate with an Early Bump in the Light Curve
Yibo Wang, Tingui Wang, Ning Jiang +7
We re-examined the classification of the optical transient ASASSN-18ap, which was initially identified as a supernova (SNe) upon its discovery. Based on newly emerged phenomena, su…
