UPDATES ON THE GLITCHING PULSAR MONITORING CAMPAIGN PERFORMED FROM IAR
Paper in proceeding, 2024

Pulsars are known for their exceptionally stable rotation. However, this stability can be disrupted by glitches, sudden increases in rotation frequency whose cause is poorly understood. In this study, we present some preliminary results from the pulsar monitoring campaign conducted at the IAR since 2019. We present measurements from timing solution fits of the parameters of five glitches: one glitch in the Vela pulsar, one in PSR J0742−2822, one in PSR J1740−3015, and two mini-glitches in PSR J1048−5832. Finally, we applied the vortex creep model to characterize the inter-glitch period of Vela. However, the preliminary results yielded highly degenerate and loosely constrained parameters.
