CosmoVerse@Krakow 2024

Our understanding of the Universe is at a turning point with the predictions of the standard cosmological 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 analysed for potential systematic uncertainties or biases. Secondly, there have been numerous advances in approaches to data analysis and statistics, 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.

CosmoVerse@Krakow is the second annual conference in a series of conferences that aim to establish a link between the different research areas in cosmology with the main focus on confronting the growing challenges of tensions in recent cosmological survey data. This conference is organized within the Cost action initiative CA21136 – Addressing observational tensions in cosmology with systematics and fundamental physics (CosmoVerse). Learn more about CosmoVerse action here.

Main topics:

• Observational cosmology and Systematics (cross-correlation of data, systematic effects)
• Data analysis (astrostatistics; data science in astronomy; Bayesian analysis; machine learning and artificial intelligence)
• Fundamental Physics (challenge of the cosmological hypothesis, dark energy and modified gravity, neutrino physics, dark energy, and dark matter interaction).

Venue: The conference will take place in Kraków at Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University.

Dates: The main conference will take place 9 July – 11 July 2024. For Management Committee members, the annual meeting will be held on the morning of 12 July 2024.
