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).
The Milky Way grew by accreting many smaller galaxies. What did these doomed galaxies leave behind, and what could they say about the Milky Way’s early past?
This paper reports the results of a cosmological simulation, and how smooth accretion and mergers affect three important aspects of galaxy formation: stellar mass growth, size increase, and morphology changes.
Supermassive black holes (SMBH) likely exist at the center of every massive galaxy in our universe. How these million to billion solar mass beasts form is not well understood. The authors in today’s astrobite examine the possibility of the direct collapse of massive gas clouds to form SMBH seeds in a computer simulation of a galaxy merger.
How well do the current methods of measuring the star formation rate of galaxies match then known star formation rate in simulations?
What’s causing the “beads on a string” pattern of star formation around this interacting galaxy pair?
