Characterizing the Formation and Evolution of S0-galaxies (CaFES-0): Revealing the origin of the mass-size relation for S0 galaxies

Diego Pallero, Yara L. Jaffe, Amelia Fraser-McKelvie +6

We investigate the structural evolution and formation pathways of lenticular (S0) galaxies using the Hydrangea suite of cosmological hydrodynamical simulations. Simulated galaxies…

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…

Something green beneath the surface: The dynamical nature of Fossil Structures in IllustrisTNG-100

Mary Verdugo-Santos, Facundo A. Gómez, Diego Pallero +2

Fossil structures (FS) have traditionally been considered dynamically relaxed end-products of group evolution, characterized by a large magnitude gap (). However,…

Characterizing the Formation and Evolution of S0-galaxies (CaFES-0): Their formation pathways around Galaxy Clusters

Diego Pallero, Yara L. Jaffé, Amelia Fraser-McKelvie +7

The formation pathways of lenticular galaxies (S0s), which lie morphologically between elliptical and spiral galaxies, remain a topic of active research. Environmental effects, mer…

Coevolution of Intracluster Light and Brightest Cluster Galaxies

Rebecca J. Mayes, Facundo A. Gómez, Antonela Monachesi

Context. Intracluster Light (ICL) is a faint stellar component of galaxy groups and clusters bound to the cluster potential, and making up a significant fraction of the cluster mas…

On the origin of counterrotating stellar disks in TNG50. I

M. C. Bugueño, Facundo A. Gómez, Arianna Dolfi +1

Understanding galaxy evolution is key to explaining the structures we observe in the present-day Universe. Counterrotating stellar disks (CRDs), i.e. co-spatial stellar disks rotat…
