Caught in the web: galaxy mergers along cosmic filaments
Carolina Dulcien, Yara L. Jaffe, Jacob P. Crossett +31
Galaxy clusters grow through the accretion of galaxies from groups, filaments, and other clusters. During this process, galaxies may undergo pre-processing in lower-density environ…

R. F. Haack, A. V. Smith Castelli, L. Sodré +22
Observational extragalactic catalogs over wide sky areas are essential for uncovering the large-scale structure of the Universe. They allow, among others, cosmological studies and…
Star-forming compact groups: Tracing the early evolutionary stages of compact group environments
Ortiz-Gómez S., Torres-Flores S., Monachesi A. +13
In the context of pre-processing -- a scenario in which galaxies quench their star formation within substructures before falling into clusters -- we investigate the impact of envir…
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…
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…
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…
Diving into dangerous tides: The impact of galaxy cluster tidal environments on satellite galaxy mass densities
Matias Blaña, Thomas H. Puzia, Yasna Ordenes-Briceño +8
Satellite galaxies endure powerful environmental tidal forces that drive mass stripping of their outer regions. Consequently, satellites located in central regions of galaxy cluste…
