DOI: 10.1017/pasa.2024.96
Abstract: Abstract The spin-down law of pulsars is generally perturbed by two types of timing irregularities: glitches and timing noise. Glitches are sudden changes in the rotational frequency of pulsars, while timing noise is a discernible… read more here.

DOI: 10.1088/1361-6382/acd0fe
Abstract: Transient signals of instrumental and environmental origins (‘glitches’) in gravitational wave data elevate the false alarm rate of searches for astrophysical signals and reduce their sensitivity. Glitches that directly overlap astrophysical signals hinder their detection… read more here.

DOI: 10.1088/1361-6382/adf58c
Abstract: We present a method to identify and categorize gravitational wave candidate triggers identified by matched filtering gravitational wave searches (pipelines) caused by transient noise (glitches) in gravitational wave detectors using support vector machine (SVM) classifiers.… read more here.

DOI: 10.1093/mnras/staa3520
Abstract: Glitch is supposed to be a useful probe into pulsar's interior, but the underlying physics remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of inertia in conventional neutron star… read more here.

DOI: 10.1093/mnras/stad1335
Abstract: A striking feature of the Vela pulsar (PSR J0835−4510) is that it undergoes sudden increases in its spin frequency, known as glitches, with a fractional amplitude on the order of 10−6 approximately every 900 days. Glitches… read more here.
