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…
Phase-space simulations of prompt cusps: simulating the formation of the first haloes without artificial fragmentation
Lurdes Ondaro-Mallea, Raul E. Angulo, Jens Stücker +2
The first generation of haloes forms from the collapse of the smallest peaks in the initial density field. -body simulations of this process suggest a prompt formation of a stee…
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…
