Decaying Dark Matter Halo Abundance from a Revised Spherical Collapse Model
Thomas Montandon, Vivian Poulin, Oliver Hahn +2
We present a semi-analytical framework for the halo mass function (HMF) in decaying dark matter (DDM) cosmologies, in which dark matter decays into a massive daughter particle inhe…
Testing the assumptions of the Effective Field Theory of Large-Scale Structure
Mandar Karandikar, Cristiano Porciani, Oliver Hahn
The Effective Field Theory of Large-Scale Structure (EFTofLSS) attempts to amend some of the shortcomings of the traditional perturbative methods used in cosmology. It models the e…
Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions
Clément Stahl, Yohan Dubois, Benoit Famaey +4
Collisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, wit…
The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys
Joop Schaye, Roi Kugel, Matthieu Schaller +17
We introduce the Virgo Consortium's FLAMINGO suite of hydrodynamical simulations for cosmology and galaxy cluster physics. To ensure the simulations are sufficiently realistic for…
Perturbation-theory informed integrators for cosmological simulations
Florian List, Oliver Hahn
Large-scale cosmological simulations are an indispensable tool for modern cosmology. To enable model-space exploration, fast and accurate predictions are critical. In this paper, w…
Rhapsody-C simulations -- Anisotropic thermal conduction, black hole physics, and the robustness of massive galaxy cluster scaling relations
Alisson Pellissier, Oliver Hahn, Chiara Ferrari
We present the Rhapsody-C simulations that extend the Rhapsody-G suite of massive galaxy clusters at the scale with cosmological m…
