Neutrino emission from an off-axis jet driven by the tidal disruption event AT2019dsg

Liu, Ruo-Yu; Wang, Xiang-Yu; Xi, Shao-Qiang

Recently, a high-energy muon neutrino event was detected in association with a tidal disruption event (TDE) AT2019dsg at the time about 150 days after the peak of the optical/UV luminosity. We propose that such an association could be interpreted as arising from hadronic interactions between relativistic protons accelerated in the jet launched fro…

Implications of a proton blazar inspired model on correlated observations of neutrinos with gamma-ray flaring blazars

Bhadra, Arunava; Majumdar, Debasish; Banik, Prabir +1 more

The recent detections of the neutrino event IceCube-170922A, 13 muon-neutrino events observed in 2014-2015 and the IceCube-141209A by IceCube observatory from the Blazars TXS 0506 +056 , PKS 0502 +049 /TXS 0506 +056 , and GB6 J1040+0617 respectively, all of which were in the state of enhanced gamma-ray emission, indicate that cosmic rays are accel…

Search for traversable wormholes in active galactic nuclei using x-ray data

Tripathi, Ashutosh; Zhou, Biao; Abdikamalov, Askar B. +2 more

In a previous paper, one of us calculated iron K α line profiles emitted from possible accretion disks around traversable wormholes as a first step to use x-ray reflection spectroscopy to search for astrophysical wormholes in active galactic nuclei. In the present paper, we extend that work and construct an XSPEC model for the whole relativistic r…
