Magnetic flares in Active Galactic Nuclei: Modeling the iron Kalpha-line
R. W. Goosmann, B. Czerny, M. Mouchet +5
The X-ray spectra of Active Galactic Nuclei (AGN) are complex and vary rapidly in time as seen in recent observations. Magnetic flares above the accretion disk can account for the…
Following the Colour of the Low Mass X-ray Binary 4U 1820-30 with INTEGRAL
Antonella Tarana, Angela Bazzano, Pietro Ubertini +2
The 4-200 keV spectral and temporal behaviour of the low mass X-ray binary 4U 1820-30 has been studied with INTEGRAL during 2003-2005. This source as been observed in both the soft…
Double Spin Asymmetries A_NN and A_SS at sqrt{s}=200 GeV in Polarized Proton-Proton Elastic Scattering at RHIC
pp2pp Collaboration, S. Bultmann, I. H. Chiang +34
We present the first measurements of the double spin asymmetries A_NN and A_SS at sqrt{s}=200 GeV, obtained by the pp2pp experiment using polarized proton beams at the Relativistic…
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…
The structure and X-ray radiation spectra of illuminated accretion disks in AGN. III. Modeling fractional variability
R. W. Goosmann, B. Czerny, M. Mouchet +5
[abridged] Extending the work of Czerny et al. (2004), we model the fractional variability amplitude due to distributions of hot spots co-orbiting on the accretion disk around a su…
Kinematical and Dynamical Modeling of Elliptical Galaxies
G. A. Mamon, E. Lokas, A. Dekel +2
Elements of kinematical and dynamical modeling of elliptical galaxies (Es) are presented. In projection, NFW models resemble Sersic models, but with a very narrow range of shapes (…
