The Research Project

Modern cosmology is based on the fact that the universe expands. The present rate of the expansion is measured in terms of the Hubble constant. One of the most intriguing problems of modern cosmology is discrepancy in the measurements of the Hubble Constant. The estimation of the Hubble constant based on observations of the Cosmic Microwave Background Radiation is inconsistent with measurement of the Hubble constant based on supernovae observations. Cosmic Microwave Background Radiation was emitted when the Universe was very young. On the other hand supernovae are located in nearby galaxies. Thus, possible explanation of the Hubble constant tension range from hypotheses concerning the early Universe or late stages of our Universe's evolution.

This PhD Project will focus on the problem of the Hubble constant tension. It will involve investigations of various scenarios either concerning the early universe, or intermediate universe, or its recent stage. The project is mostly theoretical and involves numerical modeling. However, it will also require the use of cosmological data.  

The candidate should have solid foundations in the theoretical cosmology as well as numerical skills. Statistical analysis and data handling skills are preferred but not essential.
