El Grup d' Astronomía i Astrofísica de la Universitat Politècnica de Catalunya (UPC) reuneix a un nombre reduit de persones interessades en una àmplia gama de temes de la Astronomía moderna. La història del grup va començar l'any 1995, just desprès de que alguns astrofísics perteneixents a dos departaments de física diferents (el departament de Física Aplicada, i el de Física i Enginyería Nuclear.) ajuntaran esforços per tal de crear un grup d'investigació competitiu en ciències de l'espai dins de la UPC. En la actualitat el GAA compta amb 7 investigadors permanents, a més de 6 estudiants doctorats i 11 estudiants postgraduats buscant aconseguir el seu doctorat. L'àrea principal d'actividad de la investigació del GAA pot ser classificada com Astrofísica Teórica. El tema és molt ampli, incloent-hi simulacions de computadora de les últimes etapes de la evolució estelar (l'enfriamient de les nanes blanques, AGBs, explosions de novas i supernovas, explosions de raigs X i física dels objectes compactes), estructura y dinàmica dels jets relacionats amb el PN i els objectes de l'Herbig-Haro i Cosmología. Alguns membres també estàn interessats en altres areas, incloent-hi estudis del comportament cinemàtic de estrelles en la vecindad Solar així com el diseny de la instrumentació que serà utilitzada per els satèlits científics.
