Multi-frequency monitoring of γ-ray loud blazars

The basic parameters of γ-ray-loud blazars

We determined the basic parameters, such as the central black hole mass (M), the boosting factor (or Doppler factor) (δ), the propagation angle (Φ) and the distance along the axis to the site of γ-ray production (d) for 23 γ-ray-loud blazars using their available variability timescales. In this method, the absorption effect depends on the γ-ray energy, emission size and property of the accretio...

Basic properties of Gamma-ray loud blazars

In this paper, a method is proposed to determine the basic properties of γ-ray loud blazars, among them the central black hole mass, M , the Doppler factor, δ, the propagation angle of the γ-rays with respect to the symmetric axis of a twotemperature accretion disk, Φ, and the distance (i.e. the height above the accretion disk), d at which the γ-rays are created, for seven γ-ray loud blazars wi...

Relation between γ-rays and emission lines for the γ-ray loud blazars

The relation between the γ-ray and the emission line luminosities for a sample of 36 γ-ray loud blazars is investigated; an apparent correlation between them, Lγ ∝ L 0.69±0.11 Line , with a correlation coefficient r = 0.741 and a chance probability of p = 1.9× 10, is found. It is found, however, that there is no intrinsic correlation between them: the apparent correlation is due to the redshift...

X–ray Observations of TeV Blazars and Multi-Frequency Analysis

The non-thermal spectra of blazars, observed from radio to GeV/TeV γ–rays, reveal two pronounced components, both produced by radiation by energetic particles. One peaks in the IR to soft X–ray band, radiating via the synchrotron process; the other, peaking in the high-energy γ–rays, is produced by the Compton process. These spectra – and, in particular, the ASCA data – suggest that the origin ...
