Limits on Optical Counterparts to the Repeating Fast Radio Burst 20180916B from High-speed Imaging with Gemini-North/‘Alopeke

open access: yesThe Astrophysical Journal
We report on contemporaneous optical observations at ≈10 ms timescales from the fast radio burst (FRB) 20180916B of two repeat bursts (FRB 20201023 and FRB 20220908) taken with the ‘Alopeke camera on the Gemini-North telescope.

Testing the starquake model of strangeon star via pulsar glitch observations(利用脉冲星周期跃变观测检验固态夸克星星震模型)

open access: yesZhejiang Daxue xuebao. Lixue ban
Pulsar glitch is considered as a probe of the physics inside neutron stars. However, there are mainly two hypotheses regarding the origin of glitches: the superfluid vortex model and the starquake model.

A Cacophony of Echoes from Daily Monitoring of the Crab Pulsar at Jodrell Bank

open access: yesThe Astrophysical Journal
Using archival data from the 42-foot telescope at the Jodrell Bank Observatory, we produce daily stacks of aligned giant pulses for the Crab pulsar, to study changes to the daily profiles between 2012 April and 2016 December.

Mechanism of Circular Polarization in Giant Pulses and Fast Radio Bursts

open access: yesThe Astrophysical Journal Letters
Some giant pulses and fast radio bursts (FRBs) exhibit notable circular polarization, which remains unexplained and carries significant implications for their emission mechanisms.
