Under pressure, black holes feast  SCIENCE DAILY · 1 day
A new study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies -- and the supermassive black holes within their cores -- aggregate into clusters, these... more

How close can you get to a black hole?  LIVE SCIENCE · 2 days
Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO). more

How galaxies and black holes grow together  PHYS.ORG · 1 week
Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers—and the masses of a black hole and its host galaxy are correlated. But... more
Black holes and neutron stars merge unseen in dense star clusters  PHYS.ORG · 2 weeks
Mergers between black holes and neutron stars in dense star clusters are quite unlike those that form in isolated regions where stars are few. Their associated... more

South Africa's MeerKAT solves mystery of 'X-galaxies'  PHYS.ORG · 3 weeks
Many galaxies far more active than the Milky Way have enormous twin jets of radio waves extending far into intergalactic space. Normally these go in opposite directions, coming from a massive black hole at... more
