Correlated residuals in Tully-Fisher and Fundamental Plane relations and their impact on peculiar velocity measurements

Tyann Dumerchat, Raul E. Angulo, Julian Bautista +3

The Tully-Fisher (TF) and Fundamental Plane (FP) relations are widely used to infer extragalactic distances and peculiar velocities, enabling measurements of large-scale velocity s…

The ACCEL project: simulating Lyman- forest in large-volume hydrodynamical simulations

Solène Chabanier, Corentin Ravoux, Lucas Latrille +5

Cosmological information is usually extracted from the Lyman- forest correlations using only either large-scale information interpreted through linear theory or using small-sca…

Baryon acoustic oscillations from a joint analysis of the large-scale clustering in Fourier and configuration space

Tyann Dumerchat, Julian E. Bautista

Baryon acoustic oscillations (BAOs) are a powerful probe of the expansion history of our Universe and are typically measured in the two-point statistics of a galaxy survey, either…

Galaxy clustering multi-scale emulation

Tyann Dumerchat, Julian Bautista

Simulation based inference has seen increasing interest in the past few years as a promising approach to model the non linear scales of galaxy clustering. The common approach using…

Analysis of birefringence and dispersion effects from spacetime-symmetry breaking in gravitational waves

Kellie O'Neal-Ault, Quentin G. Bailey, Tyann Dumerchat +2

In this work, we review the effective field theory framework to search for Lorentz and CPT symmetry breaking during the propagation of gravitational waves. The article is written s…
