We present the results of a long-term monitoring campaign of the TeV gamma-ray emitting blazar Mrk 501 during its active high-state in 1997. Observations at radio and optical frequencies, and in X-rays and TeV gamma-rays are included. We study the source’s intermediate-term variability at all wavelengths and discuss implications for synchrotron and synchrotron-self-Compton dominated jet models. We find that the variability on weekly time scales is consistent with an SSC model where flux variations are primarily caused by a hardening of the electron spectra (change in spectral index) and an increasing density of ultrarelativistic electrons. © 2000 American Institute of Physics.

    The April 1997 giant flare of Mkn 501 is modelled by a stationary Synchrotron-Proton-Blazar model. Our derived model parameters are consistent with X-ray-to-TeV-data in the flare state and diffusive shock acceleration of e[sup -] and p in a Kolmogorov/Kraichnan turbulence spectrum. While the...

    The BL Lac object Mrk 501 came into a high flaring state in 1997, brightest in the sky at TeV energies. Using the air shower data obtained with a high density part of the Tibet II array, being operating at Yangbajing since 1996, we searched for γ-ray signals from this source during the period...
