Impact of Eccentricity on the Population Properties of Neutron Star–Black Hole Mergers

The Astrophysical Journal
We revisit the population properties of neutron star–black hole (NSBH) mergers using low-mass compact binary coalescences reported through GWTC-4. Employing pyEFPE , an inspiral-only waveform model that captures both orbital eccentricity and spin-induced

A Search for Extra Polarizations Using a Gaussian Process in Gravitational-wave Transient Catalog 3

The Astrophysical Journal
General relativity predicts that gravitational waves are described by two polarization states: the plus + state and cross × state. However, alternate theories of gravity allow up to six polarizations.

Examining the Gap in the Chirp Mass Distribution of Binary Black Holes

The Astrophysical Journal
The mass distribution of binary black holes inferred from gravitational-wave measurements is expected to shed light on their formation mechanisms. An emerging structure in the mass distribution indicates the presence of multiple peaks around chirp masses

Lunar LIGO and gravitational wave astronomy on the Moon [PDF]

, 1994
Gravitational wave astronomy continues to be one of the exploration concepts under consideration in NASA's strategy for conducting physics and astrophysics from the lunar surface. As with other proposals for new concepts in science and astronomy from the

Trends in the Population of Binary Black Holes Following the Fourth Gravitational-wave Transient Catalog: A Data-driven Analysis

The Astrophysical Journal
Current models of binary black hole distributions are difficult to interpret because inferences hinge on modeling choices, which can mask or mimic real structure.

Optical Appearance of Eccentric Tidal Disruption Events

The Astrophysical Journal Letters
Stars approaching supermassive black holes can be tidally disrupted. Despite being expected to emit X-rays, tidal disruption events (TDEs) have been largely observed in optical bands, which is poorly understood.
