Abstract

This project focus on galaxy clusters in the context of the J-PAS survey and preliminary surveys, such as S-PLUS. Clusters are on the pinnacle of the hierarchical structure formation process in the Universe. For that reason they lie in the crossroads between astrophysics and cosmology and thus are a rich source of information regarding dark matter and energy. One of the points of this project is the full exploitation of the S-PLUS data for cluster science, starting with the detection. The high quality of the photo-z's provided by this data will allow for accurate estimations of optical mass proxies. With the aid of external data we will calibrate those proxies by using weak gravitational lensing masses. A second focus is on the development of a pipeline for galaxy shape measurements on J-PAS, aiming to use those for weak lensing. For this purpose we are leaning toward deep learning methods. This is one of the main tasks I have as one of the coordinators of the J-PAS clusters and lensing group. (AU)
