Testing unified models for the origin of ultrahigh-energy cosmic rays and neutrinos: Multimessenger approaches with x-ray observations
arXiv:2406.10944 · doi:10.1103/PhysRevD.110.043045
Abstract
The unified models of astrophysical sources to account for ultrahigh-energy cosmic rays (UHECRs) and high-energy cosmic neutrinos with energies greater than 100 TeV have been discussed. Based on model-independent arguments, we argue that if the photomeson production is the dominant mechanism, the most probable candidate sources are x-ray transient objects, allowing for the semi-transparency for the photomeson production. We develop a generic model of high-energy neutrino emitters accompanied by x-ray emission, and present how multimessenger observations can place significant constraints on the source parameters that characterize the common sources of neutrinos and UHECRs, such as the cosmic-ray loading factor. The requirements of UHECR acceleration, escape, and energetics further constrain the magnetic field and the bulk Lorentz factor of the sources. The resulting bounds provide diagnoses of the unified models, which demonstrates the importance of current and future x-ray facilities such as MAXI and Einstein Probe.
