The Search for Black Hole Teenagers
The discovery of medium-sized black holes allow us to trace the history of the giant black holes in the center of galaxies.
Finding a Supermassive Black Hole’s Stellar-Mass Friends
An archival X-ray search reveals that supermassive black holes at the center of galaxies may be surrounded by stellar-mass black hole companions.
Astrobites at AAS 233: Day 3
We report on Day 3 of the winter AAS meeting in Seattle, WA. Highlights include updates in X-ray astronomy, the discovery of a second repeating FRB, an exploration of astrochemistry in planet-forming disks, and a look at the 2020 Astronomy Decadal Survey.
Meet the AAS Keynote Speakers: Dr. Ryan Hickox
This year, the Chandra X-ray Observatory is celebrating its 20-year legacy. Dr. Ryan Hickox of Dartmouth College will explain how the resulting discoveries have shaped our view of the high-energy universe in his plenary talk at #AAS233.
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.
Black holes During the Cosmic Dawn
Black holes may seem large, but not compared to the scales we’ll talk about today.
