Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) in the intracluster medium of the cluster. However, the resilience of SCFs to subsequent minor mergers is unknown. Here we investigate the exte... Read More about Resilience of sloshing cold fronts against subsequent minor mergers.

Redshift measurement through star formation (2019)
Journal Article

© ESO 2019. In this work we use the property that, on average, star formation rate increases with redshift for objects with the same mass - the so called galaxy main sequence - to measure the redshift of galaxy clusters. We use the fact that the gene... Read More about Redshift measurement through star formation.
