Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

The interpretation of pulsar rotational glitches, the sudden increase in spin frequency of
neutron stars, is a half-century-old challenge. The common view is that glitches are driven by …

The Advanced LIGO [1] and Advanced Virgo [2] detectors have made numerous detections
of gravitational waves (GWs), to date consisting of short-duration (transient) GWs emitted …

Seven years after the first direct detection of gravitational waves, from the collision of two
black holes, the field of gravitational wave astronomy is firmly established. A first detection of …

The birth of gravitational wave astronomy was triggered by the first detection of a signal
produced by the merger of two compact objects (also known as a compact binary …

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 …

Direct detection of gravitational waves has become a powerful new tool of multi-messenger
astrophysics. Apart from short-duration (transient) events, such as the inspirals and mergers …

PSR J0537–6910 is a young (1–5 kyr) energetic X-ray pulsar, rotating at a spin frequency ν=
62 Hz (Marshall et al. 1998), in the Large Magellanic Cloud at a distance of 49.6 kpc …

∼ 6% of all known pulsars have been observed to exhibit sudden spin-up events, known as
glitches. For more than fifty years, these phenomena have played an important role in …

Neutron stars are compact and dense celestial objects that offer the unique opportunity to
explore matter and its interactions under conditions that cannot be reproduced elsewhere in …
