Circular polarization of gravitational waves from early-Universe helical turbulence
We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety of initial conditions, including driven (stationary) and decaying ...

Gravitational waves: Sources, detectors and searches [PDF]
Gravitational wave science should transform in this decade from a study of what has not been seen to a full-fledged field of astronomy in which detected signals reveal the nature of cataclysmic events and exotic objects. The LIGO Scientific Collaboration and Virgo Collaboration have recently completed joint data runs of unprecedented sensitivities to ...

Indication for a Compact Object Next to a LIGO–Virgo Binary Black Hole Merger
The astrophysical origin of binary black hole (BBH) mergers remains uncertain, although many events have been observed by the LIGO–Virgo–KAGRA network. Such mergers are potentially originated in the vicinity of massive black holes (MBHs).

Gravitational waves (GWs) from stellar binary black hole (sBBH) mergers can be strongly gravitational lensed by intervening galaxies/galaxy clusters. Only a few works have investigated cluster-lensed sBBH mergers by adopting oversimplified models, while ...

Extreme mass-ratio inspirals (EMRIs) take place when a stellar-mass black hole (BH) merges with a supermassive BH (SMBH). The gravitational-wave emission from such an event is expected to be detectable by the future Laser Interferometer Space Antenna ...

We derive models of rotating very massive stellar cores with mass ≈10 ^2 –10 ^4 M _⊙ that are marginally stable to the pair-unstable collapse, assuming that the core is isentropic and composed primarily of oxygen.

Measuring Mass and Radius of the Maximum-mass Nonrotating Neutron Star
The mass ( M _TOV ) and radius ( R _TOV ) of the maximum-mass nonrotating neutron star (NS) play a crucial role in constraining the elusive equation of state of cold dense matter and in predicting the fate of remnants from binary neutron star (BNS ...

Testing the Nature of GW200105 by Probing the Frequency Evolution of Eccentricity
GW200105 is a compact binary coalescence event, consisting of a neutron star and a black hole, observed in LIGO–Virgo–KAGRA’s third observing run.
