Galaxy evolution in compact groups - III. Structural analysis of galaxies and dynamical state of non-isolated compact groups
Gissel P. Montaguth, Ana Laura O'Mill, Claudia Mendes de Oliveira +17
Compact Groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset - non-isolated CGs - are embedded within major st…
The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
The heartbeat of stellar halos: Insights from the stellar halo mass-metallicity relation
Jenny Gonzalez-Jara, Patricia B. Tissera, Antonela Monachesi +5
This work investigates the presence and evolution of the MZhR from redshift z=3.5 to z=0, and identifies when galaxies settle on the present-day MZhR. We used central galaxies with…
Age and metallicity of low-mass galaxies: from their centres to their stellar halos
Elisa A. Tau, Antonela Monachesi, Facundo A. Gómez +5
We aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies to better understand their formation history. We use 17 simulated low-mass galaxies from th…
The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
