Title: Firewall Phenomenology with Astrophysical Neutrinos
Abstract:One of the most important features of a black hole in general relativity is its event horizon: a boundary from which nothing can escape.

There has been a recent surge of interest in the nature of these event horizons and their local neighborhoods. In an attempt to resolve black hole information paradox(es), and more generally, to better understand the path towards quantum gravity, “firewalls” have been proposed as an alternative to event horizons. In this work, we explore the phenomenological implications of black holes possessing a surface or firewall. We predict a potentially detectable signature of these firewalls in the form of a high energy astrophysical neutrino flux. We compute the spectrum of this neutrino flux in different models and show that it is a possible candidate for the source of the PeV neutrinos recently detected by IceCube.
