Masses of Black Holes in the Universe
Janusz Ziolkowski
The different methods of determination of black holes (BHs) masses are presented for three classes of BHs observed in the Universe: stellar mass BHs, intermediate mass BHs (IMBHs)…

Consistency of the black hole mass determination in AGN from the reverberation and the X-ray excess variance method
M. Nikolajuk, B. Czerny, J. Ziolkowski +1
Values of black hole masses are frequently determined with the help of the reverberation method. This method requires a specific geometrical factor related to the distribution of t…

Evolutionary constraints on the masses of the components of HDE 226868/Cyg X-1 binary system
J. Ziolkowski
Calculations carried out to model the evolution of HDE 226868, under different assumptions about the stellar wind mass loss rate, provide robust limits on the present mass of the s…
