Back to Data Analysis

The Extragalactic Sources Science Group focuses on the analysis of spectra, time variability, searches for periodicity, and cosmological aspects (EBL) of sources outside of our Galaxy.

Current Coordinators: Seiya Nozaki (Leader), Jorge Otero Santos (Deputy)

Past Coordinators: David Sanchez, Mireia Nievas Rosillo

(since April 2024)
