M.Sc. in Astronomy, 2004, UNLP, Argentina Ph.D. in Astronomy, 2007, UNLP, Argentina, "Gamma-ray emission from accreting binary systems" Current position: Researcher (CONICET), and Teacher of the Sede Andina, University of Rio Negro (UNRN). CV Publication list Contact: morellana@unrn.edu.ar The topic of my research is the astrophysic of gamma-ray sources, mainly from a theoretical point of view, including the high-energy gamma-ray emission and its propagation which can trigger electromagnetic cascades. This is a very active field that also concerns the broadband spectrum of the sources which on the one hand provide more complete physical insights and on the other generates the more interesting puzzles. As an interlude, in 2009/2010 I have tryed on protoplanetary disks' investigation, as a postdoctoral fellow at the University of Valparaíso, Chile. This allowed me to know the passive accretion disks (i.e. that reprocess the central YSO light), which are studied mostly through their IR emission. This project is aimed to find the most exciting targets to be followed up by ALMA. Nowadays I develop my research for the the National Council for Science and Technology (CONICET) at the regional facilities of Universidad Nacional de Río Negro located in the city of San Carlos de Bariloche.
