Traits of Accreting Galaxies
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
Feeding black holes, up close and personal
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.
Meet the AAS Keynote Speakers: Julie Comerford
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!
Which Are The Brightest Gravitational Wave Sources In Our Galaxy?
LISA is a space-based mission to detect gravitational waves. What will be the brightest targets it can see?
A Pebbly Barrier to Planet Formation
While a planet is forming, its passage through the protoplanetary disk can prevent pebbles from migrating inwards and accreting onto the planet.
For Whom the Cosmic Web Tolls
“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.
