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.
In this bite we will explore nucleosynthesis in the merger of
neutron stars, by the light of gravitational waves and light itself.
The most distant quasar yet discovered illuminates the early universe…
Though black holes may start as strangers, interactions between several of them — not just the two component masses — can lead to LIGO-esque mergers.
