GRB 210323A:Signature of Long-lasting Lifetime of Supra-massive Magnetar as the Central Engine from the Merger of Binary Neutron Star
《Research in Astronomy and Astrophysics》2024年第8期32-41,共10页Yingze Shan Xiaoxuan Liu Xing Yang Haoyu Yuan Houjun Lü 
supported by the Guangxi Science Foundation(grant No.2023GXNSFDA026007);the Program of Bagui Scholars Program(LHJ)。
Theoretically,a supra-massive neutron star or magnetar may be formed after the merger of binary neutron stars.GRB210323A is a short-duration gamma-ray burst(GRB)with a duration of lasting~1 s.The light curve of the pr...

A global analysis searching for neutrinos associated with black hole merger gravitational wave events
《Research in Astronomy and Astrophysics》2018年第11期11-16,共6页Yu-Zi Yang Jia-Jie Ling Wei Wang Zhao-Kan Cheng 
funded by the National Natural Science Foundation of China (Grant No. 11080922)
Several neutrino observatories have searched for coincident neutrino signals associated with gravitational waves induced by the merging of two black holes. No statistically significant neutrino signal in excess of the...
