“From Fundamental Physics to Data Analysis in Cosmology”

Venue: Mon-Repos, Corfu, Greece

Dates: The School will take place 13 May – 18 May 2024

CosmoVerseSchool@Corfu is the first School by the CosmoVerse COST Action and will centre on the interface of data analysis and fundamental physics in cosmology. Within CosmoVerse, this will feature the intersection of intersection of Working Groups 2 (Data Analysis in Cosmology) and 3 (Fundamental Physics) (see for more information). The School will cover lectures and training in the latest cosmology simulation code, together with the integration of new fundamental physics models and their use in these implementations.

Cosmological tensions
Early Dark Energy
Neutrino cosmology
Horndeski theory
Data analysis and cosmological simulations
Machine learning in cosmology

Funding: The School has no registration for all participants. The CosmoVerse COST Action will provide funding (travel/subsistence) to a number of students in attendance. However, if alternative funding is available, we ask that students take this into consideration.
The funding consists of the reimbursement of the flight costs and a daily allowance. More details and conditions can be found on the COST Rules, pp. 82-86.


Our understanding of the Universe is at a turning point with the predictions of the standard model of cosmology (or concordance model) and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. The question of cosmological tensions can be confronted in a number of ways. Firstly, survey data needs to be further analyzed for potential systematic uncertainties or biases. It would also be interesting to explore predictions from possible combined survey data, which is something survey collaborations cannot normally explore. Secondly, there have been numerous advances in approaches to data analysis and statistical approaches, some of which provide less dependence on cosmological models to make cosmological parameter estimates. Lastly, there are a plethora of new proposals from fundamental physics which range from novel neutrino physics to dark energy proposals (and others) which may contribute to a solution to the cosmological tensions problem. These represent the three research themes through which cosmological tensions will either be alleviated or resolved.

The main aim of CosmoVerse ( is to establish a synergy between these research areas and foster a sustainable network based on interdisciplinary research in order to confront the growing challenges of tensions in cosmological survey data. CosmoVerse will take a harmonized approach involving all key communities.
