Black hole masses in NLS1 galaxies from the X-ray excess variance method
M. Nikolajuk, P. Gurynowicz, B. Czerny
We estimate black hole masses in Narrow Line Seyfert 1 (NLS1) galaxies at the basis of their X-ray excess variance. We apply the standard approach appropriate for Broad Line Seyfer…

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…
