All of the black hole mergers we’ve seen so far with LIGO/Virgo have surprised us with their mass-spin relationship. Are we misunderstanding stellar collapse? Or is there something even more exotic going on?
Identifying the incidence of AGN as a function of star formation rate
Is the evolution of galaxies and their AGN driven by past mergers?
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.
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 may seem large, but not compared to the scales we’ll talk about today.
