Impact of massive binary star and cosmic evolution on gravitational wave observations I: black hole–neutron star mergers
Mergers of black hole–neutron star (BHNS) binaries have now been observed by
gravitational wave (GW) detectors with the recent announcement of GW200105 and …

A noninteracting galactic black hole candidate in a binary system with a main-sequence star
S Chakrabarti, JD Simon, PA Craig… - The Astronomical …, 2023 - iopscience.iop.org
We describe the discovery of a solar neighborhood (d= 468 pc) binary system with a main-
sequence sunlike star and a massive noninteracting black hole candidate. The spectral …

Merger rate density of Population III binary black holes below, above, and in the pair-instability mass gap
We present the merger rate density of Population III binary black holes (BHs) by means of a
widely used binary population synthesis code BSE with extensions to very massive and …

Search for a Black Hole Binary in Gaia DR3 Astrometric Binary Stars with Spectroscopic Data
We report the discovery of a candidate binary system consisting of a black hole (BH) and a
red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary …

Cygnus X-1 contains a 21–solar mass black hole—Implications for massive star winds
The evolution of massive stars is influenced by the mass lost to stellar winds over their
lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that the …

Gravitational wave sources in our galactic backyard: Predictions for BHBH, BHNS, and NSNS binaries detectable with LISA
Future searches for gravitational waves from space will be sensitive to double compact
objects in our Milky Way. We present new simulations of the populations of double black …

A stripped-companion origin for Be stars: clues from the putative black holes HR 6819 and LB-1
K El-Badry, E Quataert - Monthly Notices of the Royal …, 2021 - academic.oup.com
ABSTRACT HR 6819 is a bright (V= 5.36), blue star recently proposed to be a triple
containing a detached black hole (BH). We show that the system is a binary and does not …

New physics and the black hole mass gap
We demonstrate the power of the black hole mass gap as a novel probe of fundamental
physics. New light particles that couple to the Standard Model can act as an additional …
