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 $30 M_{⊙}$ 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…
