The author revisits a seminal article that reviews our understanding of AGN feedback, and comes out extremely impressed with the status quo (and the parallels with fictional universes).
Reproducing the observed star formation history of galaxies in simulations is a fantastic test of our understanding of galaxy evolution. This is regulated strongly by “feedback”, for example, from supernova. Today’s astrobite discusses feedback from high mass X-ray binaries.
Direct observational evidence for positive feedback from the interaction of outbursts from active black holes and the surrounding medium has been lacking so far, until now…
Active galactic nuclei are some of the most luminous objects in the universe. This paper explores how feedback from AGN could trigger star formation in their host galaxies.
Aluminum can be used for so much more than foil. What can it tell us about our solar system’s place in the galaxy? Read about today’s paper to find out more.
