An extragalactic gamma-ray binary formed in supernova 2022jli
Pengfei Zhang, Zhongxiang Wang, Shunhao Ji
On May 5 2022, a type Ic supernova (SN) explosion SN~2022jli was discovered. This SN showed additional optical emissions, which were found to exhibit 12.4-day periodic undulations…
A Disk-Originated 329-day Quasi-Periodic Oscillation in the Seyfert 1 Galaxy J1626+5120
Litao Zhu, Zhongxiang Wang, Dong Zheng +2
The Seyfert 1 galaxy J1626+5120 is estimated to host a black hole (BH) accreting at Eddington ratio . Its long-term multi-band…
AT2022sxl: A Candidate Repeating Tidal Disruption Event in Possible Association with Two High-Energy Neutrino Events
Shunhao Ji, Zhongxiang Wang, Litao Zhu +2
We report a candidate repeating tidal disruption event (TDE), AT2022sxl, found from large-field optical survey data. Two flares with a separation time of 7.2\,yr between the…
Possible Neutrino Emission from the Pulsar Wind Nebula G63.7+1.1
Shunhao Ji, Zhongxiang Wang, Dong Zheng +1
We report on our finding of an excess of neutrinos at the location of the pulsar wind nebula (PWN) G63.7+1.1. By analyzing the IceCube track-like neutrino data for…
PKS~2332017 and PMN J19161519: Candidate Blazar Counterparts to Two High-energy Neutrino Events
Shunhao Ji, Zhongxiang Wang, Dong Zheng
We report our counterpart identification study for two high-energy neutrino events IC-130127A and IC-131204A listed in the IceCube Event Catalog of Alert Tracks. These two events b…
