Targeting black holes from metal-poor progenitors with next-generation gravitational-wave detectors

We have a 3G paper today, led by Federico Leto di Priolo (recent MSc graduate here) and also featuring a new collaboration with Martyna Chruślińska from ESO. A 3G detector will see black holes at high redshift, which means they will come from stars with different properties—namely, stars with low metallicity. Now, how far should you look if you’re specifically interested in the low-metallicity…
