Detection of a flaring blazar coincident with an IceCube high-energy neutrino [PDF]
EPJ Web of Conferences, 2019 In September 22, 2017, IceCube released a public alert announcing the detection of a 290 TeV neutrino track event with an angular uncertainty of one square degree (90% containment).

Observations of Markarian 421 with the MAGIC Telescope [PDF]
The Astrophysical Journal, 2007 The MAGIC telescope took data of very high energy gamma-ray emission from the blazar Markarian 421 (Mkn 421) between November 2004 and April 2005. We present a combined analysis of data samples recorded under different observational conditions, down to gamma-ray energies of 100 GeV.

Lepto-hadronic Interpretation of 2021 RS Ophiuchi Nova Outburst
The Astrophysical Journal, 2023 Very-high-energy (VHE; 100 GeV < E ≤ 100 TeV) and high-energy (HE; 100 MeV < E ≤ 100 GeV) gamma rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS Oph) during its outburst in 2021 August by various observatories, such as the High Energy

Evidence for Multiple Shocks from the γ-Ray Emission of RS Ophiuchi
The Astrophysical Journal, 2023 In 2021 August, the Fermi Large Area Telescope, H.E.S.S., and MAGIC detected GeV and TeV γ -ray emission from an outburst of recurrent nova RS Ophiuchi. This detection represents the first very high-energy γ -rays observed from a nova, and it opens a new

Search for tau neutrinos with the MAGIC telescopes: improving selection criteria* [PDF]
EPJ Web of Conferences, 2019 MAGIC, a system of two Cherenkov telescopes located at the Roque de los Muchachos Observatory (2200 a.s.l.) in the Canary Island of La Palma, has lately been engaged in an unconventional task: the search for a signature of particle showers induced by ...

Proceedings of International Europhysics Conference on High Energy Physics — PoS(HEP2005), 2007 MAGIC (Major Atmospheric Gamma Imaging Cherenkov telescope) is presently the largest ground-based gamma ray telescope. MAGIC has been taking data regularly since October 2004 at the Roque de los Muchachos Observatory on the island of La Palma. In this paper the MAGIC telescope status, its performances and some preliminary results on observed gamma ray ...

OBSERVATIONS OF MICROQUASAR CANDIDATES WITH THE MAGIC TELESCOPE [PDF]
International Journal of Modern Physics D, 2008 We report on the results from the observations in very high energy band (VHE, Eγ ≥ 100 GeV ) of the γ-ray binary LS I +61 303 and the black hole X-ray binary (BHXB) Cygnus X-1. LS I +61 303 was recently discovered at VHE by MAGIC1 and here we present the preliminary results from an extensive observation campaign, comprising 112 observation hours ...
