Modern surveys such as DESI and \textit{Euclid}, which collect data for hundreds of millions of galaxies to map the large-scale structure (LSS) of the Universe, hold the key to det…
Secondary Dependence of Baryonic Effects on the Density Profile of Dark Matter Halos
Yikun Wang, Idit Zehavi, Sergio Contreras +3
Baryonic physics is anticipated to be a major source of systematic uncertainty in current and future large-scale cosmological surveys. We investigate how baryonic effects on halo d…
Cosmological constraints from the small scale clustering of Emission Line Galaxies

Accurate modelling of redshift-space distortions (RSD) in galaxy clustering is essential for extracting cosmological information from current and forthcoming large-scale structure…
Modelling the expulsion of baryons from haloes: the role of feedback and of the cosmological constant
Oscar Veenema, Daniele Sorini, Sownak Bose
The extent to which galactic-scale astrophysical processes conspire with the underlying cosmological model to expel baryons from haloes remains a central question in galaxy formati…
Correlated residuals in Tully-Fisher and Fundamental Plane relations and their impact on peculiar velocity measurements
