Hunting for stellar splashback: defining the size of a galaxy cluster
How big is a galaxy cluster? Today’s authors use the remnants of destroyed galaxies to define the edge of galaxy clusters.
A Sip of Reionisation to Quench the Smallest Dwarf Galaxies
Did local Ultra-Faint Dwarf Galaxies get quenched by the Milky Way or by Reionisation? Today’s authors use cosmological simulations to find out!
The Galaxy Main Sequence: What’s in the Scatter?
What processes can explain the diversity in star formation rates exhibited by galaxies of similar masses? Today’s authors investigate this using the EAGLE simulation.
Stellar Snacks or: How to Grow a Massive Black Hole through TDEs
How do tidal disruption events contribute to massive black hole growth?
Shaken, Not Stirred: Subgrid Metal Diffusion in Galaxy Simulations
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.
How to Grow a Giant Galaxy
Let’s grow a giant galaxy by z ~ 2!
