The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters
Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3
Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…
Effects of Varied Cosmic Ray Feedback from AGN on Massive Galaxy Properties
Charvi Goyal, Sam B. Ponnada, Philip F. Hopkins +3
Active galactic nuclei (AGN) provide energetic feedback necessary to `turn off' star formation in high-mass galaxies (M 10 M, $10.4 \leq \log(…
The abundance of thin dwarf galaxies: a challenge for cosmological simulations
José A. Benavides, Laura V. Sales, Julio F. Navarro +4
We study the prevalence of thin galaxies as a function of stellar mass in the range using data from the GAMA, DESI, ALFALFA, and Nearby…
Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34
We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…
Compact groups of galaxies in the TNG100 simulation
Bruno M. Celiz, José A. Benavides, Mario G. Abadi
Using the TNG100 cosmological simulation, we study the formation and evolution of compact groups of galaxies. Over a redshift range of , we identify thes…
Disks no more: the morphology of low-mass simulated galaxies in FIREbox
José A. Benavides, Laura V. Sales, Andrew Wetzel +9
We study the morphology of hundreds of simulated central galaxies in the stellar mass range \msun\, from the FIREbox cosmological volume. We demons…
The galaxy-halo connection of disc galaxies over six orders of magnitude in stellar mass
Pavel E. Mancera Piña, Justin I. Read, Stacy Kim +5
(Abridged) The relations between stellar (), gas (), baryonic (), and dark matter halo mass () provide unique cons…
The Environmental Quenching Mechanisms of Field Dwarf Galaxies
José A. Benavides, Julio F. Navarro, Laura V. Sales +2
Field dwarf galaxies not actively forming stars are relatively rare in the local Universe, but are present in cosmological hydrodynamical simulations. We use the TNG50 simulation t…
Effects of galactic environment on size and dark matter content in low-mass galaxies
Francisco J. Mercado, Jorge Moreno, Robert Feldmann +8
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,…
Large dark matter content and steep metallicity profile predicted for Ultra-Diffuse Galaxies formed in high-spin halos
José A. Benavides, Laura V. Sales, Mario. G. Abadi +3
We study the stellar properties of a sample of simulated ultra-diffuse galaxies (UDGs) with stellar mass , selected from the TNG50 simul…
Size-Mass Relations for Simulated Low-Mass Galaxies: Mock Imaging versus Intrinsic Properties
Courtney Klein, James S. Bullock, Jorge Moreno +4
The observationally-inferred size versus stellar-mass relationship (SMR) for low-mass galaxies provides an important test for galaxy formation models. However, the relationship rel…
Imposters among us: globular cluster kinematics and the halo mass of ultra-diffuse galaxies in clusters
Jessica E. Doppel, Laura V. Sales, José A. Benavides +4
The velocity dispersion of globular clusters (GCs) around ultra-diffuse galaxies (UDGs) in the Virgo cluster spans a wide range, including cases where GC kinematics suggest halos a…
DS+: a method for the identification of cluster substructures
Jose A. Benavides, Andrea Biviano, Mario G. Abadi
The study of cluster substructures is important for the determination of the cluster dynamical status, assembly history, and the evolution of cluster galaxies, and it allows to set…
Origin and evolution of ultra-diffuse galaxies in different environments
Jose A. Benavides, Laura V. Sales, Mario. G. Abadi +3
We study the formation of ultra-diffuse galaxies (UDGs) using the cosmological hydrodynamical simulation TNG50 of the Illustris-TNG suite. We define UDGs as dwarf galaxies in the s…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
Quiescent Ultra-diffuse galaxies in the field originating from backsplash orbits
José A. Benavides, Laura V. Sales, Mario. G. Abadi +8
Ultra-diffuse galaxies (UDGs) are the lowest-surface brightness galaxies known, with typical stellar masses of dwarf galaxies but sizes similar to larger galaxies like the Milky Wa…

I. Ferrero, J. F. Navarro, M. G. Abadi +2
Elliptical (E) and spiral (S) galaxies follow tight, but different, scaling laws that link their stellar masses, radii, and characteristic velocities. Mass and velocity, for exampl…
Accretion of Galaxy Groups into Galaxy Clusters
José. A. Benavides, Laura. V. Sales, Mario. G. Abadi
