Probing the Central Engine of the Narrow-Line Seyfert 1 Galaxies

Agnieszka Janiuk, Joanna Kuraszkiewicz, Bozena Czerny

The central engine of the the Narrow Line Seyfert 1 galaxies is being probed. We use the ASCA and RXTE data to model the X-ray primary continuum as well as the reflected component…

Spectral properties of the Narrow-Line Seyfert 1 Quasar PG1211+143

Agnieszka Janiuk, Bozena Czerny, Grzegorz M. Madejski

We propose a theoretical model to explain the spectrum of the quasar PG1211+143 emitted in the Optical/X-ray bands. In particular, we suggest that the inner accretion disk may deve…

Models for the UV-X emission in AGN : influence of different parameters

S. Coupé, M-C. Artru, S. Collin +2

We present the results of computations performed with a new photoionisation-transfer code designed for hot Compton thick media. Presently the code solves the transfer of the contin…

The Nature of the Emission Components in the Quasar/NLS1 PG1211+143

A. Janiuk, B. Czerny, G. M. Madejski

We present the study of the emission properties of the quasar PG1211+143, which belongs to the class of Narrow Line Seyfert 1 galaxies. On the basis of observational data analyzed…

Evolution of Active Galaxies: Black-hole Mass - Bulge relations for Narrow Line Objects

Smita Mathur, Joanna Kuraszkiewicz, Bozena Czerny

Mathur (2000) has proposed that the narrow line Seyfert 1 galaxies (NLS1s) are likely to be the active galaxies in early stage of evolution. To test this hypothesis, we have calcul…

Disk/corona model of the mean spectra of radio-quiet and radio-loud QSO

Marek Nikolajuk, Bozena Czerny

We test the disk/corona model of Janiuk et al. (2000) against the composite mean optical/UV/soft X-ray spectrum of radio loud and radio quiet quasars from Laor et al. (1997) which…
