abstract = {During a tidal disruption event, a star is torn apart by
the tidal forces of a supermassive black hole, with about
$50\%$ of the star’s mass eventually accreted by the black
hole. The resulting flare can, in extreme cases of
super-Eddington mass accretion, result in a relativistic
jet1,2,3,4. While tidal disruption events have been
theoretically proposed as sources of high-energy cosmic
rays5,6 and neutrinos7,8,9,10,11,12,13,14, stacking searches
indicate that their contribution to the diffuse
extragalactic neutrino flux is very low15. However, a recent
association of a track-like astrophysical neutrino
(IceCube-191001A16) with a tidal disruption event
(AT2019dsg17) indicates that some tidal disruption events
can accelerate cosmic rays to petaelectronvolt energies.
Here we introduce a phenomenological concordance scenario
with a relativistic jet to explain this association: an
expanding cocoon progressively obscures the X-rays emitted
by the accretion disk, while at the same time providing a
sufficiently intense external target of backscattered X-rays
for the production of neutrinos via proton–photon
interactions. We also reproduce the delay (relative to the
peak) of the neutrino emission by scaling the production
radius with the black-body radius. Our energetics and
assumptions for the jet and the cocoon are compatible with
expectations from numerical simulations of tidal disruption
events.},
