Pulsar timing arrays could localise individual sources of gravitational waves to host galaxies. The problem is, it’s so computationally difficult! This paper shows us a faster way.
What happens when a black hole merger stalls at the final parsec? Nothing, unless another black hole can shake things up a bit!
The upcoming LISA mission promises to detect many gravitational wave events, but can it attribute any of them to a host galaxy? Let’s find out!
Today’s paper discusses new galaxy merger simulations and what they tell us about the shapes galaxies can take on!
We’re still not sure what causes quasars, some of the brightest objects in the universe, to switch on. Today’s authors present a compelling case for galaxy mergers being the culprit!
The authors of today’s paper study the distribution of cold gas in a group of galaxies and use that to understand how AGNs are powered.
