Enjoyable lunch in the company of @AstroAhura Nature paper on seeding the first superstellar-mass black holes. What's best evidence? Often overlooked, but Mg/Ca vs. Ti/He in Skymapper ancient star implicates fallback onto black hole nicely: https://t.co/p
R. Ezzeddine tells us about the importance of NLTE for metal-poor stars, as well as their fantastic prefixes: hyper-metal-poor, mega-metal-poor ([Fe/H] < -7.0, Keller+2014's star), and... beyond ("ridiculously-metal-poor") https://t.co/UnmEPJ2vqp #cools
In fact, the discovery of such a star got us a @nature paper from some of our early data ([Fe/H] < -7!): https://t.co/RQLMb9ZVKG
