Tidal disruption of a super-Jupiter by a massive black hole
Marek Nikolajuk, Roland Walter
Aims: A strong, hard X-ray flare was discovered (IGR J12580+0134) by INTEGRAL in 2011, and is associated to NGC 4845, a Seyfert 2 galaxy never detected at high-energy previously. T…

NLS1 galaxies and estimation of their central black hole masses from the X-ray excess variance method
Marek Nikolajuk, Bozena Czerny, Pawel Gurynowicz
Black hole mass determination in active galaxies is a key issue in understanding various luminosity states. In the present paper we try to generalise the mass determination method…

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…
