Black hole-neutron star mergers as the origin of GRB 211211-like long-duration gamma-ray bursts

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.

Lijing Shao awarded as an Alibaba DAMO Academy Young Fellow

Dr. Rui Xu won the Galaxies 2022 Best Paper Award

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.

FAST Reveals a Dynamically Evolving Environment Around a Repeating Fast Radio Burst Source

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.

Kejia Lee Awarded the 2022 XPLORER PRIZE

Thu, 2022-09-15On September 15, the winners of the 2022 "XPLORER PRIZE" are announced. Kejia Lee, an Associate Professor at Department of Astronomy and Kavli Institute for Astronomy and Astrophysics at Peking University is listed among the 50 awardees this year.

PKU astronomers discover nearly 200 new quasars behind the Galactic plane

Mon, 2022-08-08An international research team led by astronomers from Peking University has identified 204 quasars behind the Galactic plane, 191 of which are new discoveries, using five optical telescopes in China, USA, and Australia. The new research, recently published in the Astrophysical Journal Supplement Series (ApJS), marks the successful lift-off of the spectroscopic observation campaign, after releasing the candidate catalog of quasars behind the Galactic plane with more than 160,000 sources previously selected by this team.
