VLTI/GRAVITY upper limit on near-infrared emission from the nearby 33 Msun black hole Gaia BH3
Pierre Kervella, Pasquale Panuzzo, Alexandre Gallenne +11
The recent astrometric discovery of the nearby (590 pc) massive () dormant black hole candidate Gaia BH3 offers the possibility to angularly resolve the black hole from…

A generative model for Gaia astrometric orbit catalogs: selection functions for binary stars, giant planets, and compact object companions
Kareem El-Badry, Casey Lam, Berry Holl +4
Astrometry from Gaia DR3 has produced a sample of 170,000 Keplerian orbital solutions, with many more anticipated in the next few years. These data have enormous potential to…

The Formation of Black Holes in Non-interacting, Isolated Binaries. Gaia Black Holes as Calibrators of Stellar Winds From Massive Stars
Matthias U. Kruckow, Jeff J. Andrews, Tassos Fragos +10
Context. The black holes discovered using Gaia, especially Gaia BH1 and BH2, have low mass companions of solar-like metallicity in wide orbits. For standard isolated binary evoluti…
