Blazars are the class of radio-loud active galactic nuclei (AGN) whose relativistic jets are oriented close to the line of sight of the observer.Blazars are emitting electromagnetic radiation ranging from radio to high- energy (HE; >100 MeV) and very high energy (VHE; > 100 GeV) gamma-ray bands characterized by rapid and high-amplitude variability. Blazars are also potential sources for VHE neutrino emission. The research focus of the group is to investigate the origin of broadband emission from blazars, using multiwavelength and multimessenger data, and it includes a variety of topics, such as the disk - jet connection, relativistic jet physics, particle acceleration, and emission, etc.
The group is a full member of MAGIC collaboration since 2017. MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes) is a system of two Imaging Atmospheric Cherenkov telescopes designed to detect gamma-ray photons from 25 GeV to 30 TeV. The 17-meter telescopes are located 2,200 meters above sea level on the Canary Island of La Palma. The MAGIC telescopes have been in operation since 2003, and the international collaboration of about 165 astrophysicists from 24 research institutions in eleven countries is responsible for the operation, and maintenance of the telescopes.
