Welcome to the website of Samia Drappeau.

I am a postdoctoral fellow at the Institut de Recherche en Astrophysique et Planétologie at the Université de Toulouse III, France. I did my PhD at the 'Anton Pannekoek' Astronomical Institute, University of Amsterdam, NL, under the supervision of Sera Markoff and Ralph Wijers. You can find a copy of my thesis, entitled "The Ins and Outs of Emission from Accreting Black Holes", here.

My work focuses on understanding the physics behind accreting flows and relativistic outflows around black holes in active galactic nuclei (AGN) and X-ray binaries (XRBs). In particular, I am interested in understanding how such system can accelerate particles (protons and electrons) to very high energy and what will be the resulting emission.
What is the contribution of AGN and XRBs to the total cosmic ray flux received on Earth? Will we one day detect neutrinos from these systems? How accreting black holes interact with their surroundings? These are some of the many questions I would like to answer with my research.
