On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct
detection of gravitational waves, a signal caught by the LIGO interferometers on 14 …

Binary interactions lead to the formation of intriguing objects, such as compact binaries,
supernovae, gamma ray bursts, X-ray binaries, pulsars, novae, cataclysmic variables, hot …

We describe the observation of GW170104, a gravitational-wave signal produced by the
coalescence of a pair of stellar-mass black holes. The signal was measured on January 4 …

The first gravitational wave detections of mergers between black holes and neutron stars
represent a remarkable new regime of high-energy transient astrophysics. The signals …

All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported following the O1/O2
runs have near-zero effective spins. There are only three potential explanations for this. If the …

We explore a newly proposed channel to create binary black holes of stellar origin. This
scenario applies to massive, tight binaries where mixing induced by rotation and tides …

Motivated by the recent detection of gravitational waves from the black hole binary merger
GW150914, we study the dynamical evolution of (stellar-mass) black holes in galactic nuclei …

Mergers of black hole–neutron star (BHNS) binaries have now been observed by
gravitational wave (GW) detectors with the recent announcement of GW200105 and …

The recent detections of the binary black hole mergers GW150914 and GW151226 have
inaugurated the field of gravitational-wave astronomy. For the two main formation channels …

We show that a black-hole binary with an external companion can undergo Lidov–Kozai
cycles that cause a close pericenter passage, leading to a rapid merger due to gravitational …
