Magic lantern, cinema, and their Japanese names
This paper examines the perception of Western optics and projection technologies in Japan from the 18th through the 20th centuries, which led to the development of film, television, and other forms of media.

Gamma-Ray Bursts Afterglow Physics and the VHE Domain
Afterglow radiation in gamma-ray bursts (GRB), extending from the radio band to GeV energies, is produced as a result of the interaction between the relativistic jet and the ambient medium.

The Detection of GRBs at VHE: A Challenge Lasting for More than Two Decades, What Is Next?
Unveiling the mystery of gamma-ray bursts (GRBs) has been the target of many multi-waveband observational and theoretical efforts during the last decades.

Probing photon-ALP oscillations from the flat spectrum radio quasar 4C+21.35
Flat spectrum radio quasar (FSRQ) is the most luminous blazar at the GeV energies. In this paper, we probe the photon-axion-like particle (ALP) oscillation effect on the latest very-high-energy (VHE) γ-ray observations of the FSRQ 4C+21.35 (PKS 1222+216).

Multimessenger Characterization of Markarian 501 during Historically Low X-Ray and γ-Ray Activity
We study the broadband emission of Mrk 501 using multiwavelength observations from 2017 to 2020 performed with a multitude of instruments, involving, among others, MAGIC, Fermi's Large Area Telescope (LAT), NuSTAR, Swift, GASP-WEBT, and the Owens Valley ...

The present generation of Imaging Air Cherenkov Telescopes (IACTs) has greatly improved our knowledge on the Very High Energy (VHE) side of our Universe. The MAGIC IACTs operate since 2004 with one telescope and since 2009 as a two telescope stereoscopic

INTEGRAL View of TeV Sources: A Legacy for the CTA Project
Investigations that were carried out over the last two decades with novel and more sensitive instrumentation have dramatically improved our knowledge of the more violent physical processes taking place in galactic and extra-galactic Black-Holes, Neutron ...

Upgrade of the MAGIC telescopes
The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes (IACTs) located on the Canary island of La Palma. With 17m diameter mirror dishes and ultra-fast electronics, they provide an energy threshold as low as 50 GeV for observations at low zenith angles.

AGN Observations with the MAGIC Telescope [PDF]
MAGIC is presently the imaging atmospheric Cherenkov telescope with the largest reflecting surface and the lowest energy threshold. MAGIC concluded its first year of regular observation in April 2006. During this period and the preceding commissioning phase, 25 Active Galactic Nuclei have been observed and VHE gamma-ray emission has been confirmed by 4
