Neutron stars are known to show accelerated spin-up of their rotational frequency called a
glitch. Highly magnetized rotating neutron stars (pulsars) are frequently observed by radio …

Gravitational waves (GWs) can offer a novel window into the structure and dynamics of
neutron stars. Here we present the first search for long-duration quasimonochromatic GW …

This work explores whether gravitational waves (GWs) from neutron star (NS) mountains can
be detected with current second-generation and future third-generation GW detectors. In …

Abstract t Glitches in pulsars are likely to trigger oscillation modes in the fluid interior of
neutron stars. We examined these oscillations specifically at r-mode frequencies. The …

Pulsars are spinning neutron stars which emit an electromagnetic beam. We expect pulsars
to slowly decrease their rotational frequency. However, sudden increases of the rotational …

During their most recent observing run, LIGO/Virgo reported the gravitational wave (GW)
transient S191110af, a burst signal at a frequency of 1.78 kHz that lasted for 0.104 s. While …

To date, the LIGO and Virgo observatories have made detections of numerous sources of
gravitational radiation. These detections have been of transient gravitational waves (GWs) …

Pulsars are rotating neutron stars that emit periodic electromagnetic radiation. While pulsars
generally slow down as they lose energy, some also experience glitches: spontaneous …

Machine learning can be a powerful tool to discover new signal types in astronomical data.
We here apply it to search for long-duration transient gravitational waves triggered by pulsar …

Continuous gravitational waves (CWs) are quasi-monochromatic signals expected to be
ever-present in the data of gravitational-wave (GW) detectors such as Advanced LIGO (Aasi …
