Fellowships have a duration of 48 months, on full-time employment contracts, and include two mandatory two-month international research secondments, intersectoral training opportunities, and multidisciplinar mobility.
Selected Fellows will join CEFCA's end-to-end astrophysics ecosystem: from data acquisition at the Observatorio Astrofísico de Javalambre (OAJ), through data processing at UPAD, to societal outreach at the Galáctica science centre.
