ulsars are objects with exceptionally stable spin. However, their rotational stability can be perturbedby a sudden increase in their spin frequency known as a glitch. The cause of the glitches is not clearly understoodyet. Using the antennas from the Argentine Institute of Radio Astronomy (IAR), since 2018, the PuMA collabo-ration monitors with high cadence a set of pulsars from the southern hemisphere that have shown glitches before.Here we report the detection and characterization of: i) two glitches in the pulsar PSR J1048−5832, which arethe smallest of the 7 glitches previously detected on this pulsar; ii) the most recent glitch in the Vela pulsar, andiii) a glitch in PSR J0742−2822, which is the strongest glitch reported for this pulsar so far.
