TL;DR
This study analyzes 12 radio pulsars over several years, identifying 31 glitches and observing diverse post-glitch behaviors, including exponential recoveries and long-term frequency changes, enhancing understanding of pulsar glitch phenomena.
Contribution
It reports 18 new glitches, updates previous glitch data, and provides detailed analysis of glitch recovery behaviors and their implications for pulsar internal dynamics.
Findings
18 new glitches detected
Exponential recoveries observed in large glitches
Bimodal distribution of glitch sizes validated
Abstract
Data are gathered from the Parkes pulsar data archive of twelve young radio pulsars, with the intervals of data for each pulsar ranged between 2.8 years and 6.8 years. 31 glitches are identified by using phase connection from "pulsar timing" technology, ranging from to at the change in relative glitch sizes , where is the pulse frequency. 8 post-glitch behaviours of 13 published glitches are updated with 4 exponential recoveries observed. Detecting 18 new glitches has great significance, but only one exponential relaxation was discovered in these new glitches. The bimodal distribution of , as before, is validated with peaks at and . Moreover, all exponential decays were observed in large glitches, and have very low . It takes short time toward the extrapolation of the pre-glitch…
