A search for black holes with metal-poor stellar companions: I. Survey sample selection and single epoch radial velocity follow-up
Casey Y. Lam, Joshua D. Simon, Kareem El-Badry +3
Stellar-mass black holes (BHs) above are predicted to form from low-metallicity progenitors, but direct detections of such systems in the Milky Way remain scarce. Moti…
A Spectroscopic Search for Dormant Black Holes in Low-Metallicity Binaries
Pranav Nagarajan, Kareem El-Badry, Henrique Reggiani +9
The discovery of the massive black hole (BH) system Gaia BH3 in pre-release Gaia DR4 data suggests that wide BH binaries with luminous companions may be significantly overrepresent…
A Fast, Analytic Empirical Model of the Gaia Data Release 3 Astrometric Orbit Catalog Selection Function
Casey Y. Lam, Kareem El-Badry, Joshua D. Simon
In June 2022, the Gaia mission released a catalog of astrometric orbital solutions for 168,065 binary systems, by far the largest such catalog to date. The catalog's selection func…
