Fast and robust Bayesian Inference using Gaussian Processes with GPry
Jonas El Gammal, Nils Schöneberg, Jesús Torrado +1
We present the GPry algorithm for fast Bayesian inference of general (non-Gaussian) posteriors with a moderate number of parameters. GPry does not need any pre-training, special ha…
What it takes to solve the Hubble tension through modifications of cosmological recombination
Nanoom Lee, Yacine Ali-Haïmoud, Nils Schöneberg +1
We construct data-driven solutions to the Hubble tension which are perturbative modifications to the fiducial CDM cosmology, using the Fisher bias formalism. Taking as proof of…
CosmicNet II: Emulating extended cosmologies with efficient and accurate neural networks
Sven Günther, Julien Lesgourgues, Georgios Samaras +4
In modern analysis pipelines, Einstein-Boltzmann Solvers (EBSs) are an invaluable tool for obtaining CMB and matter power spectra. To accelerate the computation of these observable…
Constraints on extended Bekenstein models from cosmological, astrophysical, and local data
Léo Vacher, João F. Dias, Nils Schöneberg +5
Searching for variations of nature's fundamental constants is a crucial step in our quest to go beyond our current standard model of fundamental physics. If they exist, such variat…
One likelihood to bind them all: Lyman- constraints on non-standard dark matter
Deanna C. Hooper, Nils Schöneberg, Riccardo Murgia +3
Recent cosmological tensions have rekindled the search for models beyond CDM that cause a suppression of the matter power spectrum. Due to the small scales accessible to Lyman-$…
A step in the right direction? Analyzing the Wess Zumino Dark Radiation solution to the Hubble tension
Nils Schöneberg, Guillermo Franco Abellán
The Wess Zumino Dark Radiation (WZDR) model first proposed in arXiv:2111.00014 shows great promise as a well-motivated simple explanation of the Hubble tension between local and CM…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
