Expérimental et théorique
The 21 cm hydrogen line is a crucial resource for radioastronomy. The hydrogen element has witnessed many important epochs in the early Universe. The full spectrum of the hydrogen line arising from the red shifted emissions is therefore a highly sought for resource for cosmology and radioastronomy. In this project which can lead to a PhD, we will use the tools of quantum sensing using superconducting circuits to probe the 21 cm line first for low redshifts and devise techniques to extend this to lower frequencies, suitable for understanding important questions in particular related to dark matter in the early Universe during the Cosmic Dawn.
