Title: Measuring Cosmic Distances
Time: July/Sep 2025 (to be agreed)
Project description: Modern physics is unable to explain independent determinations of the expansion of the Universe. This problem called the Hubble tension provide a strong evidence for new physics. In order to solve the Hubble tension and eventually pave a road for new physics one has to measure cosmic distances with much better precision and accuracy. Cosmic distances are one of the most challenging and fascinating fields of modern astrophysics. The international team called the Araucaria works on this topic since 2020 -> https://araucaria.camk.edu.pl/.
We offer an introduction to the topic and a possibility to join one of the projects on precision distance determinations, which include pulsating stars (Cepheids, RR Lyrae, ect), eclipsing binaries, TRGB, JAGB, and other distance indicators. This project may include observations in our dedicated observatory in Chile.
Requirements: basic knowledge of astrophysics, programming and computer skills. Only on-site option with a possibility to continue collaboration remotely.
