Searching for signatures of fuzzy dark matter in cosmic filament profiles

Callum J. O'Kane, Alfonso Aragón-Salamanca, Ulrike Kuchner +1

Current observations reveal persistent tensions with the standard cold dark matter paradigm, raising the question of whether these can be explained by baryonic physics alone or req…

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…

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 i…

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 life and times of dark matter haloes: what will I be when I grow up?

Julian Onions, Frazer Pearce, Alexander Knebe +6

Are the most massive objects in the Universe today the direct descendants of the most massive objects at higher redshift? We address this question by tracing the evolutionary histo…

CHANCES, the Chilean Cluster Galaxy Evolution Survey: Selection and initial characterisation of clusters and superclusters

Cristóbal Sifón, Alexis Finoguenov, Christopher P. Haines +43

CHANCES, the CHileAN Cluster galaxy Evolution Survey, will study the evolution of galaxies in and around 100 massive galaxy clusters from the local Universe out to , and…
