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…
Gaussian Lagrangian Galaxy Bias
Jens Stücker, Marcos Pellejero-Ibáñez, Rodrigo Voivodic +1
Understanding -- that is the statistical relation between matter and galaxies -- is of key importance for extracting cosmological information from galaxy sur…
Probabilistic Lagrangian bias estimators and the cumulant bias expansion
Jens Stücker, Marcos Pellejero-Ibáñez, Raul E. Angulo +2
The spatial distribution of galaxies is a highly complex phenomenon currently impossible to predict deterministically. However, by using a statistical relation, it…
Characterizing Structure Formation through Instance Segmentation
Daniel López-Cano, Jens Stücker, Marcos Pellejero Ibañez +2
Dark matter haloes form from small perturbations to the almost homogeneous density field of the early universe. Although it is known how large these initial perturbations must be t…
An adaptively refined phase-space element method for cosmological simulations and collisionless dynamics
Oliver Hahn, Raul E. Angulo
N-body simulations are essential for understanding the formation and evolution of structure in the Universe. However, the discrete nature of these simulations affects their accurac…
