Research interests

My early interests were focused on general relativity, particularly the description of rotating bodies and properties of the Kerr metric representing a rotating black hole. In 1978 I started to work under the supervision of Bohdan Paczynski on the theory of accretion disks. In my Ph. D. thesis (supervisor: J.S. Stodolkiewicz) I showed that the accretion in the innermost region of the disk is transonic and the character of accretion (i.e. its stability) strongly depends on viscosity of accreting gas. In 1984 --- 1988 I concentrated on the properties of galactic and extragalactic X--ray sources. I collaborated with a number of scientists from Harvard/Smithsonian Center for Astrophysics and the University of Leicester . My contribution to these papers was to provide theoretical models for the observational data and to prepare non-standard analysis of the X-ray data. Spectral models included the presence of the hot corona in AGN accretion disks and the emission from the boudary layer in case of accretion onto neutron star. X-ray timing analysis included the fractal approach. In collaboration with Marek Abramowicz, Jan Piotr Lasota i Ewa Szuszkiewicz we developed a model of advection dominated optically thick flow. Since 1989 I constrained myself to active galactic nuclei and started more systematic multiwavelenth approach to study the basic physical components necessary to construct a universal model of the phenomenon of accretion onto a supermassive black hole, and to support the idea that such a model explains the nature of AGN activity. The published papers include both broad band study of spectra as well as spectral features like iron line and Lyman edge. I collaborate with Suzy Collin and her group on the application of the advanced spectral models based on accurate solution of radiative transfer. I analyse the time dependence of the AGN emission through power spectra and structure function analysis, and I develope the models of time dependent accretion process. My most recent reserach includes the application of quasars in cosmology - observational determination of the dark energy distribution.
