It is my pleasure to present this focus issue on Astrophysical Black Holes, guest edited by David Merritt and Luciano Rezzolla:
The issue features 10 articles which cover recent developments in the observational and theoretical understanding of black holes – both stellar mass and supermassive – as well as black holes in alternate theories of gravity. The context is astrophysical; that is: how black holes form in, and interact with, their stellar and galactic environments, and the observational consequences of that interaction.
The full issue is available from IOPscience for free for the next 3 months. I hope you will enjoy reading the articles and that they will be useful references for your future research.
