Do we really understand how black holes grow? Using new methods to run high resolution simulations, the authors of this paper investigate the evolution of gas near a supermassive black hole – and their results have serious implications for the models commonly used in cosmological simulations.
Some galaxies live peaceful lives, calmly making stars at a sedate pace, with supermassive black holes that don’t vomit jets of material. Other galaxies… not so much. Come to Professor Julie Comerford’s upcoming #AAS232 talk to learn more about the weird and wonderful world of active galactic nuclei!
LISA is a space-based mission to detect gravitational waves. What will be the brightest targets it can see?
While a planet is forming, its passage through the protoplanetary disk can prevent pebbles from migrating inwards and accreting onto the planet.
“No [galaxy] is an island entire of itself; every [galaxy] / is a piece of the [cosmic web], a part of the main” – apologies to John Donne for butchering his poem.
A white dwarf binary system that sometimes shows evidence of a magnetic field — but only some of the time.
