Improved recipes for peculiar velocity power spectra using Evolution Mapping
Matteo Esposito, Ariel G. Sánchez, Julien Bel +1
We present new fitting functions for the velocity divergence auto- and cross-power spectra, and , calibrated on gravity-only -body simulations. By app…
GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1878
GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively…
Evolution mapping III: A new recipe for the halo mass function
Andrea Fiorilli, Andrés N. Ruiz, Ariel G. Sanchez +1
We present a new prescription for the halo mass function (HMF) built upon the Evolution Mapping framework. This approach provides a physical motivation to parametrise the non-unive…
Aletheia: Emulating the non-linear matter power spectrum in the context of evolution mapping
Ariel G. Sanchez, Andrés N. Ruiz, Facundo Rodriguez +7
We present Aletheia, a new emulator of the non-linear matter power spectrum, , built upon the evolution mapping framework. This framework addresses the limitations of traditi…
Fast, Accurate and Perturbative Forward Modeling of Galaxy Clustering Part II: Redshift Space
Julia Stadler, Fabian Schmidt, Martin Reinecke +1
Forward modeling the galaxy density within the Effective Field Theory of Large Scale Structure (EFT of LSS) enables field-level analyses that are robust to theoretical uncertaintie…
Evolution mapping II: describing statistics of the non-linear cosmic velocity field
Matteo Esposito, Ariel G. Sánchez, Julien Bel +1
We extend the evolution mapping approach, originally proposed by Sanchez (2022) to describe non-linear matter density fluctuations, to statistics of the cosmic velocity field. This…
