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…
STRAWBERRY: Finding haloes in the gravitational potential
Tamara R. G. Richardson, Jens Stücker, Raul E. Angulo
Here, we present a novel algorithm that discriminates between bound and unbound particles by consideration of the gravitational potential from an accelerated reference frame -- als…
Excursion Sets with a "Perfect" Collapse Model
A. M. Wisłocka, J. Stücker, O. Hahn +1
The CDM model predicts structure formation across a vast mass range, from massive clusters () to Earth-mass micro-haloes ($\sim 10^{-6} \, \text{M}_…
Probabilistic Estimators of Lagrangian Shape Biases: Universal Relations and Physical Insights
Francisco Maion, Jens Stücker, Raul E. Angulo
The intrinsic alignment of galaxies is a key factor in modeling weak-lensing observations and can serve as a valuable signal for both cosmological and astrophysical studies. Modell…
