Spoiler alert: this paper is a bit sad. Stellar-mass black-hole binaries are now detected by LIGO on a weekly basis. It would be really cool if LISA (a future space mission targeting low-frequencies gravitational waves) could see them as well. … Continue reading
Supermassive black holes in binaries and their accretion discs… Spins align on some timescale, but migration also takes place. Do gas discs have enough time to align the spins? Well, the secret is the mass ratio: light secondaries might prevent … Continue reading
Black-hole kicks are powerful. I mean, really powerful. They can even eject supermassive black holes from the heavier galaxies in our Universe. And then these galaxies are left “empty”… Davide Gerosa, Alberto Sesana.Monthly Notices of the Royal Astronomical Society 446 (2015) … Continue reading
Paper on alignment between supermassive black holes and their accretion disks. Maybe it takes a bit longer… Giuseppe Lodato, Davide Gerosa. Monthly Notices of the Royal Astronomical Society Letters 429 (2013) L30-L34.arXiv:1211.0284 [astro-ph.CO].
