    First Results on Long-Term Multiwavelength Variability Analysis in Mrk 421 by Racero Elena, de la Calle Ignacio

    Published 2013-12-01
    “…Due to the broad-band nature of the emission from blazars, strong efforts are being placed in recent years on simultaneous multiwavelength campaigns as a way to understand the mechanisms responsible for the acceleration of ultra-relativistic particles in these objects. …”

    The Search for Neutrinos from TXS 0506+056 with the ANTARES Telescope by Illuminati Giulia

    Published 2019-01-01
    “…A high-energy neutrino, IC170922A, detected by the IceCube experiment was found to be positionally coincident with the direction of a known blazar, TXS 0506+056, observed in γ-rays and at other wavelengths of the electromagnetic spectrum. …”

    The intrinsic gamma-ray spectrum of TXS 0506+056: intergalactic propagation effects by Saveliev, A, Batista, RA

    Published 2020
    “…The recent observation of high-energy neutrinos from the 2017 flare of the blazar TXS 0506+056, together with counterparts across the whole electromagnetic spectrum, opens up new possibilities for investigating the properties of this class of objects as well as the traversed medium. …”

    Probing intergalactic magnetic fields with simulations of electromagnetic cascades by Alves Batista, R, Saveliev, A, Sigl, G, Vachaspati, T

    Published 2016
    “…We employ the so-called “Large Sphere Observer” method to efficiently simulate blazar gamma ray halos. We study magnetic fields with a Batchelor spectrum and with maximal left- and right-handed helicities. …”

    A pure hadronic model description of the observed neutrino emission from the tidal disruption event AT2019dsg by Prabir Banik, Arunava Bhadra

    Published 2022-06-01
    “…Here, we examine whether the IceCube-170922A along with the broadband electromagnetic emission from the source can also be described by a pure hadronic emission employing the proton blazar inspired (PBI) model, which takes into account the non-relativistic protons that emerge under the charge neutrality situation of the blazar jet and thus offers sufficient target matter for pp interactions with shock-accelerated protons. …”

    Cherenkov telescope array extragalactic survey discovery potential and the impact of axion-like particles and secondary gamma rays by De Franco, A, Inoue, Y, Sánchez-Conde, M, Cotter, G

    Published 2017
    “…We make use of both the latest blazar gamma–ray luminosity function and spectral energy distribution to derive the expected number of detectable sources for both the planned Northern and Southern arrays of the CTA observatory. …”

    An Exceptional Radio Flare in Markarian 421 by Richards Joseph L., Hovatta Talvikki, Lister Matthew L., Readhead Anthony C. S., Max-Moerbeck Walter, Savolainen Tuomas, Angelakis Emmanouil, Fuhrmann Lars, Aller Margo F., Aller Hugh D., Myserlis Ioannis, Karamanavis Vassilis

    Published 2013-12-01
    “…In September 2012, the high-synchrotron-peaked (HSP) blazar Markarian 421 underwent a rapid wideband radio flare, reaching nearly twice the brightest level observed in the centimeter band in over three decades of monitoring. …”
