Tue, 2022-12-13Recently, Peking University PhD student Jinping Zhu, advised by Prof. Zhuo Li, showed that a peculiar class of long-lasting gamma-ray bursts, like GRB 211211, which lack bright supernova counterparts but are associated with candidate kilonova, can indeed originate from black hole-neutron star mergers. Most long-duration gamma-ray bursts (duration longer than about 2 seconds) are typically thought to be derived from core collapses of massive stars, which produce also bright supernovae.

Thu, 2022-09-22Using a simple gravity model that breaks Lorentz symmetry in the Standard-Model Extension framework, Rui Xu, Yong Gao, and Lijing Shao from KIAA, found an imprint that deviates from the prediction of general relativity (GR) in the continuous GWs from freely precessing, rapidly rotating neutron stars.

Thu, 2022-09-22In a Nature paper published on 21 September 2022, the FAST FRB team reported using FAST to monitor FRB 20201124A for about 2 months. They analyzed 1,863 bursts of FRB 20201124A detected by FAST in totally 84-hour observations obtained across 54 days, which is the largest sample of bursts recorded with polarization information so far. The high event rate makes FRB 20201124A among the most active known FRBs. They discovered several phenomena never detected before, the irregular short-time variation of the Faraday rotation measure, which probes the line-of-sight magnetic field strength, of individual bursts during the first 36 days, followed by a constant value; they witnessed the quenching of the burst activity on a timescale shorter than three days; they detected prominent circular polarization in these bursts (up to 75%); they detected ooscillations in fractional linear and circular polarizations as well as polarization angle as a function of wavelength.
