High-energy astrophysical neutrino fluxes are, for many applications, modeled as simple power laws as a function of energy. While this is reasonable in the case of neutrino production in hadronuclear pp sources, it typically does not capture the behavior in photohadronic pγ sources: in that case, the neutrino spectrum depends on the properties of the target photons the cosmic rays collide with and on possible magnetic-field effects on the secondary pions and muons. We show that the neutrino… Expand

Theoretical interpretation of the observed neutrino emission from Tidal Disruption Events
The observation of a neutrino at IceCube in association with the Tidal Disruption Event (TDE) AT2019dsg, has suggested TDEs as a new class of sources of astrophysical neutrinos. We present a model ofExpand


We discuss simplified models for photo-meson production in cosmic accelerators, such as active galactic nuclei (AGNs) and gamma-ray bursts (GRBs). Our self-consistent models are directly based on theExpand
Interpretation of neutrino flux limits from neutrino telescopes on the Hillas plot
We discuss the interplay between spectral shape and detector response beyond a simple E^-2 neutrino flux at neutrino telescopes, at the example of time-integrated point source searches usingExpand
Neutrino emission from gamma-ray burst fireballs, revised.
It is concluded that the baryonic loading of the fireballs, which is an important control parameter for the emission of cosmic rays, can be constrained significantly with the full-scale experiment after about ten years. Expand
Improved photomeson model for interactions of cosmic ray nuclei
Photon-hadronic interactions are important for the sources and the transport of Ultra-High Energy Cosmic Rays (UHECRs). Current state-of-the-art cosmic ray transport simulations handle nuclearExpand
Energy dependent neutrino flavor ratios from cosmic accelerators on the Hillas plot
Abstract We discuss neutrino fluxes and energy dependent flavor ratios of cosmic accelerators as a function of the size of the acceleration region and the magnetic field, which are the parameters ofExpand
Photohadronic Origin of the TeV-PeV Neutrinos Observed in IceCube
We perform an unbiased search of the origin of the recently observed 28 events above ~30 TeV in the IceCube neutrino observatory, assuming that these are (apart from the atmospheric background) ofExpand
Multiwavelength and Neutrino Emission from Blazar PKS 1502 + 106
In 2019 July, the IceCube experiment detected a high-energy neutrino from the direction of the powerful blazar PKS 1502+106. We perform multiwavelength and multimessenger modeling of this source,Expand
On the direct correlation between gamma-rays and PeV neutrinos from blazars
We study the frequently used assumption in multi-messenger astrophysics that the gamma-ray and neutrino fluxes are directly connected because they are assumed to be produced by the same photohadronicExpand
Tomographic Constraints on High-Energy Neutrinos of Hadronuclear Origin.
Mounting evidence suggests that the TeV-PeV neutrino flux detected by the IceCube telescope has mainly an extragalactic origin. If such neutrinos are primarily produced by a single class ofExpand
Leptohadronic single-zone models for the electromagnetic and neutrino emission of TXS 0506+056
While active galactic nuclei with relativistic jets have long been prime candidates for the origin of extragalactic cosmic rays and neutrinos, the BL Lac object TXS 0506+056 is the firstExpand
