CPP15 - Cologne-Prague Meeting in Prague 2015: From supermassive black holes to star formation in galactic nuclei

Printer-friendly versionPDF version

Scientific rationale

Recent discoveries in Galactic center and AGN physics have been achieved through high-resolution observations that are subsequently compared to theoretical and computational models. The Cologne-Prague meeting 2015 will bring together two very active groups to support their long-term collaboration in the area of galactic nuclei. The dates of the meeting (November 9-10 2015) may be also considered symbolic because of the almost exact 100th anniversary of Einstein's general relativity. Talks will be mainly focused on the current problems of the Galactic center and AGN physics.
