Prospects for Simultaneously Detecting Long and Short Duration Gravitational Waves from Pulsar Glitches with Current and Future Detectors
Abstract
The internal mechanisms that drive the sudden change in rotation frequency in pulsar glitches could emit gravitational waves (GWs) at multiple time scales. The potential for GW analyses to detect both long and short forms of emission ("tCW-like" and "burst-like") improves as the detectors increase in sensitivity. We aim to examine how future detectors fare in making this joint measurement. By examining past glitches from the ATNF catalog, we quantify the double-detectability prospects of current- and next-generation GW detector networks. We further explore what astrophysical constraints could be placed following a double non-detection using extrapolations from the 2024 Vela pulsar glitch as a stand-in example. We find that a network with at least one next-generation detector greatly increases the probability of double-detection for many known glitching pulsars and improves the detection threshold in glitch energy by nearly two orders of magnitude over existing LIGO detectors. Additionally, double non-detections with networks with at least one next-generation detector could place dramatically improved limits on properties of the pulsar.
