Description
The MAGIC Collaboration is integrated by 20 research institutes and university departments from Armenia, Bulgaria, Finland, Germany, Italy, Poland, Spain, Switzerland and USA. The collaboration comprises two 17m diameter telescopes, located at the Roque de los Muchachos Observatory, designed to measure the Cherenkov radiation associated with atmospheric showers from very high-energy gamma rays.
CTA is a major international collaboration for building two large Cherenkov observatories at North and South Hemispheres. Roque de los Muchachos Observatory in La Palma has been selected to host the Northern observatory. The first large size telescope was inaugurated in October 2018, and we are presently building the other three.

Extreme HBL behavior of Markarian 501 during 2012Aims: We aim to characterize the multiwavelength emission from Markarian 501 (Mrk 501), quantify the energy-dependent variability, study the potential multiband correlations, and describe the temporal evolution of the broadband emission within leptonic theoretical scenarios.

New GTC spectroscopic data and a statistical study to better constrain the redshift of the BL Lac RGB J2243 + 203We present new spectroscopic data of the BL Lac RGB 2243 + 203, and its surroundings, obtained with the OSIRIS Multi Object Spectrograph (MOS) mounted in the Gran Telescopio Canarias (GTC). The spectra of neither the BL Lac nor its host galaxy show any spectral feature, thus hindering direct determination of its redshift. The spectroscopic redshiftRosa González, D. et al.

Discovery of TeV γ-ray emission from the neighbourhood of the supernova remnant G24.7+0.6 by MAGICSNR G24.7+0.6 is a 9.5 kyrs radio and γ-ray supernova remnant evolving in a dense medium. In the GeV regime, SNR G24.7+0.6 (3FHL J1834.1-0706e/FGES J1834.1-0706) shows a hard spectral index (Γ ˜ 2) up to 200 GeV, which makes it a good candidate to be observed with Cherenkov telescopes such as MAGIC.

Multi-wavelength characterization of the blazar S5 0716+714 during an unprecedented outburst phaseContext. The BL Lac object S5 0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC observations were triggered by the optical flux observed in Phase A, corresponding to the brightest ever reported state of the source in the R-band. Aims.TheAhnen, M. L. et al.

Detection of persistent VHE gamma-ray emission from PKS 1510-089 by the MAGIC telescopes during low states between 2012 and 2017Context. PKS 1510-089 is a flat spectrum radio quasar strongly variable in the optical and GeV range. To date, very high-energy (VHE, > 100 GeV) emission has been observed from this source either during long high states of optical and GeV activity or during short flares. Aims: We search for low-state VHE gamma-ray emission from PKS 1510-089. WeAcciari, V. A. et al.

Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopesFast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious, motivating searches for counterparts at other wavelengths.

Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observationsContext. The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE) gamma-ray emitter. Gamma-ray fluxes above the sensitivity limits of current Cherenkov telescopes have been predicted for both the central X-ray binary system and the interaction regions ofMAGIC Collaboration et al.

A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia AIt is widely believed that the bulk of the Galactic cosmic rays is accelerated in supernova remnants (SNRs). However, no observational evidence of the presence of particles of PeV energies in SNRs has yet been found. The young historical SNR Cassiopeia A (Cas A) appears as one of the best candidates to study acceleration processes. Between 2014Ahnen, M. L. et al.
