Advances in Reverberation Mapping
This contribution briefly reviews the reverberation mapping technique which leads to determination of black hole masses. I focus on the emerging relation between the broad-line region size and the active galactic nucleus (AGN) luminosity, and on an overview of recent results of reverberation mapping studies which are starting to cover the full AGN luminosity range. Preliminary results and time ...
متن کاملThe broad-band spectrum of 3C 120 observed by BeppoSAX
We study a broad-band X-ray observation by BeppoSAX of the broad-line radio galaxy 3C 120. The primary X-ray continuum is well described by a power law with the photon index of Γ ∼ 1.85± 0.05 and a high-energy break or a cutoff. The obtained e-folding energy of ∼ 100–300 keV corresponds to kT ∼ 50 keV in thermal-Compton models. A soft X-ray excess is found at a statistical significance of & 98%...
متن کاملX-ray Emission from the Radio Jet in 3c 120
We report the discovery of X-ray emission from a radio knot at a projected distance of 25′′ from the nucleus of the Seyfert galaxy, 3C 120. The data were obtained with the ROSAT High Resolution Imager (HRI). Optical upper limits for the knot preclude a simple power law extension of the radio spectrum and we calculate some of the physical parameters for thermal bremsstrahlung and synchrotron sel...
متن کاملA Warm Hot Intergalactic Medium towards 3c 120?
We observed the Seyfert I active galaxy/broad line radio galaxy 3C 120 with the Chandra high energy transmission gratings and present an analysis of the soft X-ray spectrum. We identify the strongest absorption feature (detected at > 99.9% confidence) with O VIII Lyα (FWHM = 1010+295 −265 km s −1), blueshifted by −5500± 140 km s−1 from systemic velocity. The absorption may be due to missing bar...
