Marek Sikora (astronomer)



Marek Sikora is a Polish astronomer.

He achieved his Habilitation of astrophysics in 1990 from University of Warsaw. He received the title of professor in 1999. Currently he works as a professor in the Centrum Astronomiczne im. Mikołaja Kopernika PAN, Polish Academy of Sciences in Warsaw. He is interested mainly high energy astrophysics, astrophysical jets, the nuclei of active galaxies, and sources of cosmic radiation.
