X-ray emission maps and scaling relations in IllustrisTNG and MillenniumTNG: Differences between cluster and group regimes
Franklin Aldás, Facundo A. Gómez, Volker Springel +3
X-ray observations are a primary probe of the intracluster medium, widely used to infer galaxy cluster masses and scaling relations. We present and validate a pipeline to generate…

Differences in the Physical Properties of Satellite Galaxies within Relaxed and Disturbed Galaxy Groups and Clusters
F. Aldás, Facundo A. Gómez, C. Vega-MartÃnez +2
Galaxy groups and clusters are the most massive collapsed structures in the Universe. Those structures are formed by collapsing with other smaller structures. Groups and cluster me…
