Debiasing Local Cluster Infall Reveals : Application to the Virgo Cluster
Bastien Carreres, David Benisty, Jenny Wagner +3
Galaxy recession velocities are commonly used to measure the Hubble constant, , with peculiar velocities treated as random noise. Around massive clusters, however, these motio…
Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations
Corentin Ravoux, Bastien Carreres, Julian Bautista +60
Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…
A Simulation Based Inference Approach to Modelling of Type Ia Supernova Populations
B. Popovic, M. Grayling, M. O'Callaghan +10
Type Ia Supernovae (SNe Ia) are prominent cosmological probes, utilising a standardisation process to reduce their observed scatter to mag. A growing number of models se…
The Peculiar Growth of Structure: Validating Measurements from TITAN Type Ia Supernovae and the Uchuu Simulations
Mitchell Dixon, David O. Jones, Nicole E. Drakos +11
The growth rate of cosmic structure, parameterized by , is a fundamental test of CDM and general relativity. Using Type Ia supernova (SN Ia) peculiar velocities in conjunc…
Calibration-Induced Systematics in SALT3 Training and Their Impact on Dark Energy Constraints from Stage IV Supernova Surveys
Kene Anumba, David O. Jones, Richard Kessler +13
In the coming years, the Vera Rubin Observatory's Legacy Survey of Space and Time (Rubin-LSST) and the Nancy Grace Roman Space Telescope's (Roman) High Latitude Time Domain Survey…
Study of the anisotropy of cosmic expansion on ZTF type Iasupernovae simulations
C. Barjou-Delayre, P. Rosnet, C. Ravoux +29
The cosmological principle assumes the isotropy of the Universe at large scales. It is a foundational assumption in the CDM model, which is the current standard model of cosmolo…
