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…

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…

Simulating the complexity of the dark matter sheet II: halo and subhalo mass functions for non-cold dark matter models
Jens Stücker, Raul E. Angulo, Oliver Hahn +1
We present "sheet+release" simulations that reliably follow the evolution of dark matter structure at and below the dark matter free-streaming scale, where instabilities in traditi…
