Assembly bias from nuisance to probe II: Salvaging linear clustering from DESI and SDSS data
Nelson Padilla, Dante Paz, Iván Lacerna
Galactic conformity links the properties of neighbouring galaxies and is usually interpreted as a signature of assembly-biased galaxy occupation. We study projected and redshift-sp…
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…
The nature of assembly bias - II. Halo spin
Ivan Lacerna, Nelson Padilla
We study an assembly-type bias parametrized by the dimensionless spin parameter that affects massive structures. In numerical simulations higher spin haloes are more strongly clust…
The nature of assembly bias - I. Clues from a LCDM cosmology
Ivan Lacerna, Nelson Padilla
We present a new proxy for the overdensity peak height for which the large-scale clustering of haloes of a given mass does not vary significantly with the assembly history. The pea…
