Description
Rapidly rotating pulsars are known to undergo spontaneous increases in their rotation frequency known as "glitches" which interrupt their normal spindown rate. While the precise mechanism is unknown, this process is believed to be due to an internal exchange of angular momentum. Such a process may cause the emission of gravitational waves across multiple frequency bands and timescales which could offer valuable insights on the internal superfluid structure of these stars. In this talk, we present the results of a search for gravitational waves from the 2024 Vela pulsar glitch across multiple timescales with data from the fourth LIGO-Virgo-KAGRA observing run and the astrophysical implications of the results. We also discuss how next-generation gravitational wave detectors could teach us more about the internal structure and possibly superfluid effects.
