Nuclei in high-energy neutrino sources: A multimessenger study of in-source propagation
AmirFarzan Esmaeili, Arman Esmaili, Pasquale Dario Serpico
The joint observation of astrophysical sources in gamma rays and neutrinos can provide invaluable insight into the physical conditions of the source, including its size, particle d…

Time-of-Flight Constraints on Neutrino Millicharge from Supernova Neutrinos in Galactic Magnetic Fields
Pedro Dedin Neto, AmirFarzan Esmaeili, Guilherme A. Nogueira +2
A millicharged neutrino propagating through magnetic fields experiences a small Lorentz-force deflection, which induces a geometric time delay. In the ultra-relativistic regime rel…

Pair production with capture by energetic cosmic ray nuclei in a photon background
AmirFarzan Esmaeili, Arman Esmaili, Pasquale Dario Serpico
We investigate the ionization state of very energetic cosmic ray nuclei in photon fields, such as the cosmic microwave background (CMB) in extragalactic propagation and the environ…
