Mrk 501 long-term multi-band photometry
Listed in IVOA Registry (Virtual Observatory)
Radio-to-TeV observations of the bright nearby (z=0.034) blazar Markarian 501 (Mrk 501), performed from December 2012 to April 2018, are used to study the emission mechanisms in its relativistic jet.
Description
We examined the multi-wavelength variability and the correlations of the light curves obtained by eight different instruments, including the First G-APD Cherenkov Telescope (FACT), observing Mrk 501 in very high-energy (VHE) gamma-rays at TeV energies.
We identified individual TeV and X-ray flares and found a sub-day lag between variability in these two bands. The source was found to be variable on different timescales. Simultaneous TeV and X-ray variations with almost zero lag are consistent with synchrotron self-Compton (SSC) emission, where TeV photons are produced through inverse Compton scattering.

The characteristic time interval of 5-25 days between TeV flares is consistent with them being driven by Lense-Thirring precession.
