UHECRs Propagation and their Multimessengers: Upper limits and the Impact of the Extragalactic Magnetic Field
Rodrigo Sasse, Rubens Costa, Adriel G. B Mocellin +2
The detection of high-energy astrophysical multimessengers establishes a connection between ultra-high-energy cosmic rays (UHECRs) and powerful cosmic accelerators. Interactions of…

Shadows and amplitude luminosity of an embedded rotating black hole
Abraao J. S. Capistrano, Antonio C. Gutierrez-Pineres, Carlos H. Coimbra-Araujo
We investigate a rotating black hole embedded in a five-dimensional flat bulk by extending the Kerr metric through the Gurses-Gursey line element. Employing Boyer-Lindquist coordin…

Multi-messenger particles as a probe for UHECR luminosity
Rodrigo Sasse, Adriel G. B. Mocellin, Rita C. dos Anjos +1
Very-high energy (GeV-TeV) gamma rays in the universe suggest the presence of an accelerator in the source. Neutrinos and gamma rays are intriguing astrophysical messengers. Multi-…
