Constraints on parameters of dark matter and black hole in the Galactic Center

AF Zakharov, F De Paolis, G Ingrosso… - Physics of Atomic Nuclei, 2010 - Springer
A concept of dark matter (DM) is introduced. As for other anomalies, we describe two ways to
solve DM problem, namely a conservative way when we have to find substances with DM …
