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 third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

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 …

We study the electrodynamics of a kinetically mixed dark photon cloud that forms through
superradiance around a spinning black hole, and design strategies to search for the …

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 …

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 …

More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of
gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of …

We study the prospects for the detection of continuous gravitational signals from normal
Galactic neutron stars, ie, nonrecycled stars. We use a synthetic population generated by …

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 …
