A lot of physics happens below the resolution limit of galaxy simulations that must be represented with “subgrid” models. Today’s paper shows the importance of including a subgrid model for the mixing of metals in galaxy simulations.
The early universe is a period of intense star formation across nearly all galaxies. Is it possible tell these galaxies apart from each other, when the universe was less than a few billion years old?
Accounting for the uncertainty in supernova explosion parameters can substantially change the star formation history and morphology of galaxy simulations.
What can outflowing gas tell us about the connection between rapid galaxy growth and AGN activity?
Mysterious emissions are coming from the other side of the wall in a quasar!
Major galaxy mergers are thought to be one of the main ways of producing massive elliptical galaxies. Surprisingly though, some of the most massive galaxies in the local universe have gas disks. Here’s how they might be made.
