Large scale structure prior knowledge in the dark siren method
Charles Dalang, Bartolomeo Fiorini, Tessa Baker
Gravitational wave dark sirens are a powerful tool for cosmology and inference of compact object population hyperparameters. They allow for a measurement of the luminosity distance…
K-mouflage at high : extending the reach of
Ashim Sen Gupta, Bartolomeo Fiorini, Tessa Baker
The code is an efficient dark matter simulation suite that flexibly handles the Horndeski family of modified gravity models. In this work we extend the scope of…
Euclid preparation. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-CDM models
Euclid Collaboration, B. Bose, P. Carrilho +229
We investigate the approximations needed to efficiently predict the large-scale clustering of matter and dark matter halos in beyond-CDM scenarios. We examine the normal branch…
Matter Power Spectra in Modified Gravity: A Comparative Study of Approximations and -Body Simulations
Benjamin Bose, Ashim Sen Gupta, Bartolomeo Fiorini +9
Testing gravity and the concordance model of cosmology, CDM, at large scales is a key goal of this decade's largest galaxy surveys. Here we present a comparative study of dark…
The Stability of the BAO Linear Point under Modified Gravity
Jaemyoung Jason Lee, Bartolomeo Fiorini, Farnik Nikakhtar +1
Baryon Acoustic Oscillations (BAOs) are crucial in cosmological analysis, providing a standard ruler, as well as constraints on dark energy. In General Relativity models, the BAO L…
