Does an AGN help or hurt star formation?
A Seyfert 2 galaxy’s energetic nucleus creates impressive twin outflows, but how are they affecting its star formation?
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.
What’s the powerhouse of the AGN?
Hint: It’s not mitochondria.
Clearing up the Redshifts of Obscured AGNs
The redshifts of active galactic nuclei (AGNs) can help us piece together the universe’s evolutionary timeline. Unfortunately, measuring these redshifts can be pretty tricky. In today’s astrobite, we look at a trick for estimating and constraining the redshifts of AGNs that are – ironically enough – partially obscured from our view.
Reionizing the universe, with a quasar assist
What role did quasars play in reionizing the early universe?
