  • The Blazar TXS 0506+056 Ass... The Blazar TXS 0506+056 Associated with a High-energy Neutrino: Insights into Extragalactic Jets and Cosmic-Ray Acceleration
    Ansoldi, S.; Arcaro, C.; Babi, A. ... Astrophysical journal. Letters, 08/2018, Letnik: 863, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    A neutrino with energy ∼290 TeV, IceCube-170922A, was detected in coincidence with the BL Lac object TXS 0506+056 during enhanced gamma-ray activity, with chance coincidence being rejected at ∼3 ...

  • The relentless variability ... The relentless variability of Mrk 421 from the TeV to the radio
    Arbet-Engels, A.; Baack, D.; Balbo, M. ... Astronomy and astrophysics (Berlin), 03/2021, Letnik: 647
    Journal Article
    Recenzirano
    Odprti dostop

    Context. The origin of the γ -ray emission of the blazar Mrk 421 is still a matter of debate. Aims. We used 5.5 years of unbiased observing campaign data, obtained using the FACT telescope and the ...

  • A cut-off in the TeV gamma-... A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia A
    Ahnen, M. L; Arcaro, C; Bangale, P ... Monthly notices of the Royal Astronomical Society, 12/2017, Letnik: 472, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract It 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 ...

  • Black hole lightning due to... Black hole lightning due to particle acceleration at subhorizon scales
    Aleksić, J.; Ansoldi, S.; Antonelli, L. A. ... Science (American Association for the Advancement of Science), 11/2014, Letnik: 346, Številka: 6213
    Journal Article
    Recenzirano
    Odprti dostop

    Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet formation using radio interferometry but ...

  • MAGIC observations of the d... MAGIC observations of the diffuse γ -ray emission in the vicinity of the Galactic center
    Baack, D.; Barres de Almeida, U.; Becerra González, J. ... Astronomy and astrophysics (Berlin), 10/2020, Letnik: 642
    Journal Article
    Recenzirano
    Odprti dostop

    Aims. In the presence of a sufficient amount of target material, γ -rays can be used as a tracer in the search for sources of Galactic cosmic rays (CRs). Here we present deep observations of the ...

  • Detection of the Geminga pu... Detection of the Geminga pulsar with MAGIC hints at a power-law tail emission beyond 15 GeV
    Asano, K.; Babić, A.; Baquero, A. ... Astronomy and astrophysics (Berlin), 11/2020, Letnik: 643
    Journal Article
    Recenzirano
    Odprti dostop

    We report the detection of pulsed gamma-ray emission from the Geminga pulsar (PSR J0633+1746) between 15 GeV and 75 GeV. This is the first time a middle-aged pulsar has been detected up to these ...

    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT By studying the variability of blazars across the electromagnetic spectrum, it is possible to resolve the underlying processes responsible for rapid flux increases, so-called flares. We ...
