Inferring Jet Physics from Neutron Star–Black Hole Mergers with Gravitational Waves
The Astrophysical JournalNeutron star–black hole (NSBH) mergers that undergo tidal disruption may launch jets that could power a gamma-ray burst (GRB). We use a population of simulated NSBH systems to measure jet parameters from the gravitational waves emitted by these systems ...

Gravitational wave astronomy— astronomy of the 21st century [PDF]
, 2011 An enigmatic prediction of Einstein's general theory of relativity is gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein's theory, the existence of gravitational waves was firmly established.

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

Lighthouses of Gravitational Wave Astronomy [PDF]
, 2006 Gravitational wave detectors capable of making astronomical observations could begin to operate within the next year, and over the next 10 years they will extend their reach out to cosmological distances, culminating in the space mission LISA. A prime target of these observatories will be binary systems, especially those whose orbits shrink measurably ...

Examining the Gap in the Chirp Mass Distribution of Binary Black Holes
The Astrophysical JournalThe 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

The Astrophysical JournalCurrent 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 LettersStars 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.
