The Circle of Life… of Black Holes
Today’s post presents SIMBA, a cosmological simulation that focuses on understanding the growth and evolution of black holes and their host galaxy.
Tiny Stars in a Tiny Orbit: A New Ultracompact Binary
NICER discovers that an accreting millisecond pulsar is actually in a record-setting orbit of 38 minutes with a white dwarf, making it the shortest orbit for this type of X-ray pulsar!
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?
