When good galaxies go bad: a new mechanism for galaxy death
Why are so many modern galaxies not actively forming stars? Today’s guest post by Katherine Lee explores one mechanism that may quench star formation in Milky Way-like galaxies.
A spiral galaxy that doesn’t play by the rules
Galaxies in the middle of clusters are usually huge, elliptical galaxies. So what is this spiral-shaped imposter doing here?
When Two Black Holes Quarrel, a Third Rejoices
Put three supermassive black holes in one simulation and let them fight over the center stage. Will there be a survivor?
Two Paths Diverged in a Cosmological Simulation: on the Formation Pathways of S0 Galaxies
Today’s bite explores the two main pathways of S0 galaxy formation, ram-pressure stripping and galaxy mergers.
Self-Interacting Dark Matter: A Better Destroyer of Galaxies
When galaxies fall into galaxy clusters, the consequences can be quite epic. But are they more epic with Self-Interacting Dark Matter? Today’s paper suggests the answer is yes. Bite also available in Dutch / Deze Bite is ook beschikbaar in het Nederlands!
Mergers and AGN go hand-in-hand…or do they??
The authors of today’s paper dig deep into the debate of whether galaxy mergers are major players in triggering AGN at intermediate redshifts.
