| Abstract | After a low state since 2002, bright outbursts in 2016 were surrounded byintermediate activity (2015-2018). Past observations have revealed a peak-shifttowards higher energies hinting an EHBL-like nature, fast intranight andlongterm variability as well as complex correlation patterns between wavebands.These features challenge a simple one-zone synchrotron self-Compton model. Werequest MAGIC observations coordinated with simultaneous multi- wavelengthobservations spanning a wide energy range, to understand the evolution of thebroadband spectrum, compare different flux states, characterize variabilitypatterns, study inter-band correlations and investigate the potential of thesource as astrophysical neutrino emitter. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
