Deteccion de un glitch en PSR J1048–5832 desde el IAR

Abstract

Pulsars are magnetized and very dense neutron stars. Their very high moment of inertia renders them with an extraordinarily stable rotation, making pulsars one of the most accurate clocks in the Universe. However, the rotational stability of some pulsars is disturbed by glitches, which consist of a sudden increase of the rotation frequency of the pulsar. The physical mechanism behind these glitches is still not well understood. The PuMA collaboration has been monitoring with high cadence since 2017 a set of pulsars from the southern hemisphere that had shown glitches before by using the antennas from the Argentine Institute of Radio astronomy (IAR). In the present study, we report the detection of a glitch in the pulsar PSR J1048−5832 and its characterization through the pulsar timing technique. This glitch is the smallest of the seven glitches reported in this pulsar.
