Discovery of Three Glitches in the previously quiet pulsar PSR J1637 $-$ 4642

Zhaoyi Wang, Chuwen Zheng, Yuhong Zhuang +4

We present the discovery and analysis of three rotational glitches in the young pulsar PSR J1637 $-$ 4642. The timing observations span from 19 February 2009 to 6 October 2024 (MJD 5…

Internal superfluid response and torque evolution in the giant glitch of PSR J1718-3718

Peng Liu, Zhonghao Tu, Jianping Yuan +1

We investigate the post-glitch rotational evolution of pulsars by analyzing the 2007 giant glitch of PSR J1718 $-$ 3718 using a vortex creep model that incorporates both inward and o…

Discovery of the anti-glitch in PSR J1835 $-$ 1106

Mingyang Wang, Peng Liu, Jianping Yuan +7

We report the detection of an anti-glitch with a fractional frequency change of $I^ I^½/ I^½ = - 3.46 (6) \times 1 0^{- 9}$ in the rotation-powered pulsar PSR J1835 $-$ 1106 at MJD 55813, based…
