Testing the equivalence principle across the Universe: a model-independent approach with galaxy multi-tracing
Sveva Castello, Ziyang Zheng, Camille Bonvin +1
We present a test of the equivalence principle on cosmological scales. This cornerstone of general relativity has been tested with high precision for standard matter, but its valid…
Testing the cosmological Euler equation: viscosity, equivalence principle, and gravity beyond general relativity
Ziyang Zheng, Malte Schneider, Luca Amendola
We investigate how the cosmological Euler equation can be tested in the presence of viscous dark matter, violations of the equivalence principle (EP), and modifications of gravity,…
The distribution of Bayes' ratio
Luca Amendola, Vrund Patel, Ziad Sakr +2
The ratio of Bayesian evidences is a popular tool in cosmology to compare different models. There are however several issues with this method: Bayes' ratio depends on the prior eve…
The prior dependence of the DESI results
Vrund Patel, Amlan Chakraborty, Luca Amendola
In this short contribution, we explore the prior dependence of the recent DESI results, according to which a Bayesian comparison of CDM with CDM cosmologies favors dyna…
Testing the cosmological Poisson equation in a model-independent way
Ziyang Zheng, Ziad Sakr, Luca Amendola
We show how one can test the cosmological Poisson equation by requiring only the validity of three main assumptions: the energy-momentum conservation equations of matter, the equiv…
