On the Cosmic Variance of the Merger Rate Density of Binary Neutron Stars

The Astrophysical Journal
The cosmic variance on the star formation history may lead to bias in the merger rate density estimation of binary neutron star (BNS) mergers by compact binary population synthesis. In this paper, we take advantage of the large box size of the Millennium

Gravitational Waves from Generalized Newtonian Sources [PDF]

Fortschritte der Physik, 2019
AbstractI review the elementary theory of gravitational waves on a Minkowski background and the quadrupole approximation. The modified conservation laws for energy and momentum keeping track of the gravitational‐wave flux are presented. The theory is applied to two‐body systems in bound and scattering states subject to newtonian gravity generalized to ...

Indication for a Compact Object Next to a LIGO–Virgo Binary Black Hole Merger

The Astrophysical Journal Letters
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).
