Observations at the Haute-Provence Observatory

I had the amazing opportunity to spend a week at the Haute-Provence Observatory and use the T120 telescope. We delved into Fritz Zwicky's work, aiming to replicate the results that revealed the "missing mass" problem within galaxy clusters. We took visible-light images of the Coma Cluster with the T120 telescope and then utilized post-processing techniques to estimate the cluster's luminous mass, comparing it to its virial mass. Throughout the week, we gained valuable experience in operating a telescope of this scale and learned how to post-process astronomical images. The experience was immensely enriching, particularly due to the historical significance of this cluster.
