“…The statistical significance of this result (> 3σ) together with previous works (e.g. Padovani & Resconi 2014;Resconi et al 2017;Lucarelli et al 2017Lucarelli et al , 2019IceCube Collaboration 2018b;Aublin 2019) show that there is a persistent and growing evidence that IBL/HBL sources are the most likely counterparts of a fraction of IceCube's high-energy neutrinos.…”

“…Several studies have reported hints on the correlation between blazars and the arrival direction of astrophysical neutrinos (Padovani & Resconi 2014;Padovani et al 2016;Lucarelli et al 2017Lucarelli et al , 2019; but see also IceCube Collaboration 2017c) and possibly of Ultra High Energy Cosmic Rays (Resconi et al 2017). Padovani et al (2016) have correlated the second catalogue of hard Fermi-LAT sources (2FHL, E > 50 GeV, Ackermann et al 2016) and other catalogues, with the then publicly available highenergy neutrino sample detected by IceCube.…”

The association of two IceCube detections, the IceCube-170922A event and a neutrino flare, with the blazar TXS 0506+056, has paved the way for the multimessenger quest for cosmic accelerators. IceCube has observed many other neutrinos but their origin remains unknown. To better understand the reason for the apparent lack of neutrino counterparts we have extended the comprehensive dissection of the sky area performed for the IceCube-170922A event to all the 70 public IceCube high-energy neutrinos that are well reconstructed and off the Galactic plane. Using the multi-frequency data available through the Open Universe platform, we have identified numerous candidate counterparts of IceCube events. We report here the classification of all the γ-ray blazars found and the results of subsequent statistical tests. In addition, we have checked the 4LAC, 3FHL and 3HSP catalogues for potential counterparts. Following the dissection of all areas associated with IceCube neutrinos, we evaluate the data using a likelihood-ratio test and find a 3.23 σ (post-trial) excess of HBLs and IBLs with a best-fit of 15 ± 3.6 signal sources. This result, together with previous findings, consistently points to a growing evidence for a connection between IceCube neutrinos and blazars, the most energetic particle accelerators known in the Universe.

“…The object had been previously observed by Fermi-LAT and had shown a brightening in the GeV band since 2017 April. The observations of the AGILE instrument in a 13 days window around the event were consistent with the Fermi-LAT observations [131]. The observations of TXS 0506+056 at very high energy with the Cherenkov instruments HESS, VERITAS, MAGIC showed no gamma ray emission during the first days [110], [23].…”

Multi-messenger astrophysics combines multifrequency astronomy in the electromagnetic domain with non photonic information carriers, gravitational waves, neutrinos, cosmic rays, to provide complementary information about cosmic sources. The present paper reviews the recent developments in the instrumentation and the first results of multi-messenger astronomy: the detection of a binary neutron star merger and of high energy neutrinos from a cosmic source.

“…The case for blazars being neutrino sources, however, is mounting. Several studies have reported hints of a correlation between blazars and the arrival direction of astrophysical neutrinos (Padovani & Resconi 2014;Padovani et al 2016;Lucarelli et al 2017Lucarelli et al , 2019; but see also Ice-Cube Collaboration 2017b) and possibly of Ultra High Energy Cosmic Rays (Resconi et al 2017). Moreover, very recently some of us ) have extended the detailed dissection of the region around the IceCube-170922A event related to TXS 0506+056 carried out by Padovani et al (2018) to all the 70 public IceCube high-energy neutrinos that are well reconstructed (so-called tracks) and off the Galactic plane.…”

The day after the arrival of the IceCube neutrino 200107A 3HSP J095507.9+355101, an extreme blazar with synchrotron peak frequency 5 × 10 17 Hz, z = 0.557, and well within the neutrino event error region, was found to exhibit a very hard X-ray flare. We report here on its multi-messenger data and classify the source as an unlikely "masquerading" BL Lac, contrary to TXS 0506+056, the first source so far associated with IceCube neutrinos. Similarly to TXS 0506+056, however, 3HSP J095507.9+355101 is also way off the so-called "blazar sequence". Finally, we discuss some theoretical implications in terms of neutrino production. We show that, based on all of the above, 3HSP J095507.9+355101 is a very plausible counterpart to an IceCube neutrino.
