Extending evolution mapping to massive neutrinos with COMET
A. Pezzotta, A. Eggemeier, G. Gambardella +7
We introduce an extension of the evolution mapping framework to cosmological models that include massive neutrinos. The original evolution mapping framework exploits a degeneracy i…
Vlasov Perturbation Theory applied to CDM
Mathias Garny, Dominik Laxhuber, Roman Scoccimarro
We apply the framework of Vlasov Perturbation Theory (VPT) to the two-loop matter power spectrum within CDM cosmologies. The main difference to Standard Perturbation Theory (SP…
Vlasov Perturbation Theory and the role of higher cumulants
Mathias Garny, Roman Scoccimarro
We develop a new approach to Vlasov Perturbation Theory (VPT) that solves for the hierarchy of cumulants of the phase-space distribution function to arbitrarily high truncation ord…
Boosting galaxy clustering analyses with non-perturbative modelling of redshift-space distortions
Alexander Eggemeier, Nanoom Lee, Román Scoccimarro +4
Redshift-space distortions (RSD), caused by the peculiar velocities of galaxies, are a key modelling challenge in galaxy clustering analyses, limiting the scales from which cosmolo…
