New surveys for supernovae to study Dark Energy

点击翻译按钮获取中文摘要

In the late 1990s Type Ia supernovae were used as standard candles to discover that the rate of expansion of the universe is accelerating, leading to the idea that some mysterious "dark energy" is pushing the universe apart. Despite much better measurements nowadays, our lack of understanding of dark energy remains one of the most fundamental problems in Physics.Several new telescopes and surveys are being planned to address this issue. The student will use a combination of archival supernova data, new data from state-of-the-art telescopes and simulated data to study statistical properties of supernovae as distance indicators. Based on these studies, he/she will help to optimise large surveys for cosmology that are planned with future telescopes and instruments, such as the Rubin Observatory, ESA's Euclid mission and 4MOST (the 4meter Multi-Object Spectrograph Telescope). This project will lead up to the start of operation of these exciting telescopes.
