The progenitor galaxies of the intracluster light
Rebecca J. Mayes, Facundo A. Gómez, Antonela Monachesi
Intracluster Light (ICL) is a diffuse stellar component of galaxy groups and clusters, bound to the structure's potential rather than to individual galaxies and primarily formed th…
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…
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…
The distribution and origin of metals in simulated Milky Way-like galaxies
Federico G. Iza, Cecilia Scannapieco, Sebastián E. Nuza +6
In this study, we investigate the distribution and origin of chemical elements in different stellar components of simulated Milky Way-like galaxies in relation to their mass assemb…
Auriga Streams III: the mass-metallicity relation does not rule out tidal mass loss in Local Group satellites
Alexander H. Riley, Rebekka Bieri, Alis J. Deason +6
The mass-metallicity relation is a fundamental galaxy scaling law that has been extended to the faintest systems in the Local Group. We show that the small scatter in this relation…
Auriga Superstars: Improving the resolution and fidelity of stellar dynamics in cosmological galaxy simulations
Ruediger Pakmor, Francesca Fragkoudi, Robert J. J. Grand +7
Cosmological hydrodynamical simulations have become an indispensable tool to understand galaxies. However, computational constraints still severely limit their numerical resolution…
The formation and evolution of Supermassive disks in IllustrisTNG
Diego Pallero, Gaspar Galaz, Patricia B. Tissera +4
Supermassive disks are outstanding galaxies whose formation and evolution are still poorly understood. They comprise a large variety of objects, ranging from large, low-surface-bri…
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…
Shaping the Milky Way: The interplay of mergers and cosmic filaments
Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +12
The large-scale morphology of Milky Way (MW)-mass dark matter (DM) halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive sat…
Stream Automatic Detection with Convolutional Neural Network (SAD-CNN)
Alex Vera-Casanova., Nicolas Monsalves Gonzalez, Facundo A. Gómez +8
Context. Galactic halos host faint substructures, such as stellar streams and shells, which provide insights into the hierarchical assembly history of galaxies. To date, such featu…
