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…
