QSO B0218+357 is currently the only gravitationally lensed source from which very-high-energy (VHE, 100GeV) gamma-ray emission has been detected. We report the multiwavelength mon- itoring observations of this source performed between 2016 and 2020 in radio interferometry, optical, X-ray and gamma-ray bands. During the monitoring individual flares and hints of en- hanced states in optical, X-ray and GeV bands have been observed, and the simultaneous data taken by the MAGIC telescopes allow us to search for the VHE gamma-ray emission associated with these events.

Abstract
QSO B0218+357 is currently the only gravitationally lensed source from which very-high-energy (VHE, 100GeV) gamma-ray emission has been detected. We report the multiwavelength mon- itoring observations of this source performed between 2016 and 2020 in radio interferometry, optical, X-ray and gamma-ray bands. During the monitoring individual flares and hints of en- hanced states in optical, X-ray and GeV bands have been observed, and the simultaneous data taken by the MAGIC telescopes allow us to search for the VHE gamma-ray emission associated with these events.File in questo prodotto:
