The Messy Pasts of Dead Ultra-diffuse Galaxies
Are past interactions to blame for the death of isolated, ultra-diffuse galaxies? Today’s authors use the IllustrisTNG simulations to find out.
Genetically modified galaxies: The impact of different merger histories on stellar haloes
How does a galaxy’s past impact its present day surroundings? Today’s authors use genetically modified simulations to investigate the effect of merger histories on stellar haloes.
Dwarfs from ELVES: The structure of dwarf satellite galaxies
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
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.
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.
