Abstract Mrk 421, one of the brightest TeV gamma-ray sources in the sky, is one of the BL Lac objects which have two broad emission maxima at higher energies than normal BL Lac objects show, one at X-ray energies and one at TeV energies. Both maxima are separated by a deep and sharp minimum which lies exactly in the energy range of INTEGRAL and which is nearly unexplored. Both emission components are believed to be connected via a common particle population which creates both emission components by different physical emission processes (Synchrotron and inverse Compton). This conjecture can be tested by simultaneous observations at different wavelengths looking for time correlations of the measured intensities. Moreover with INTEGRAL the transition region can be explored for the first time. It is the aim of this proposal to observe Mrk 421 with INTEGRAL when it is in an active state together with radiotelescopes, IR, optical, X-ray telescopes and with Cherenkov telescopes.In its quiescent state at hard X-rays and low Gamma-rays Mrk 421 is too weak to be observable by the two main instruments (IBIS and SPI) of INTEGRAL in the r^ant energy range. Therefore an observation of this source with INTEGRAL makes only sense when it is in an active state. So we ask for a ToO observation of this source when it is active.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
