Emulating galaxy and peculiar velocity clustering on non-linear scales
T. Dumerchat, J. Bautista, C. Ravoux +37
We explore the potential of cross-correlating galaxies and peculiar velocities on non-linear scales to enhance cosmological constraints. Leveraging the \textsc{AbacusSummit} simula…

Interacting Dark Sector (ETHOS ): Cosmological Constraints from SPT Cluster Abundance with DES and HST Weak Lensing Data
A. Mazoun, S. Bocquet, J. J. Mohr +64
We use galaxy cluster abundance measurements from the South Pole Telescope (SPT) enhanced by Multi-Component Matched Filter (MCMF) confirmation and complemented with mass informati…

The Dark Energy Survey : Detection of weak lensing magnification of supernovae and constraints on dark matter haloes
P. Shah, T. M. Davis, D. Bacon +62
The residuals of the distance moduli of Type Ia supernovae (SN Ia) relative to a Hubble diagram fit contain information about the inhomogeneity of the universe, due to weak lensing…
