๐ New preprint! ๐ A short technical noteโof interest to folks working on black hole perturbation theory. I give conditions for a handy gauge choice to also freeze the location of the event horizon of a black hole. "Can a radiation gauge be horizon-locking?" https://arxiv.org/abs/2404.10113
Lots of NANOGrav folks are rightly making the news; I want to highlight Prof. Sarah Vigeland, who shies away from the limelight, but is the chair of the NG gravitational-wave Detection working group. It's meticulous scientists like Sarah who make sure the analysis is right!
