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.
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
How big is a galaxy cluster? Today’s authors use the remnants of destroyed galaxies to define the edge of galaxy clusters.
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.
