Universality in the Transition from Inspiral to Plunge for Extreme-Mass-Ratio-Inspirals: High-Accuracy Analytic Solutions and Catastrophe Theory

Ariadna Ribes Metidieri, Béatrice Bonga, Badri Krishnan +1

We revisit the transition from inspiral to plunge for extreme mass-ratio inspirals on quasi-circular, inclined orbits in Kerr spacetime from the perspective of catastrophe theory.…

GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1839

GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively…

Searches for Continuous Gravitational Waves from Supernova Remnants in the first part of the LIGO-Virgo-KAGRA Fourth Observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1764

We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data…

Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853

Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…

Uncovering subdominant multipole asymmetries in binary black-hole mergers

Jannik Mielke, Angela Borchers, Frank Ohme

In dynamically formed binaries, the spins of the black holes tend to be misaligned with the system's orbital angular momentum. This causes the spins to precess and leads to an asym…

Constraints on gravitational waves from the 2024 Vela pulsar glitch

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1774

Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, sudden frequency ch…
