Simulations of Electromagnetic Cascades in the Intergalactic Medium with Plasma Instabilities: the grplinst Code
Rafael Alves Batista, Andrey Saveliev
Electromagnetic cascades initiated by TeV gamma rays from distant blazars provide one of the cleanest indirect probes of the intergalactic medium and, in particular, of intergalact…
Exploring New Propagation Scales With Galactic Neutrinos
Miller MacDonald, Kiara Carloni, Carlos A. Argüelles +2
The recent observation of high-energy Galactic neutrinos by IceCube allows for searches of new physics affecting neutrino propagation on scales of $O(10^9-10^{15})\,\mathrm{km/GeV}…
The impact of gamma-ray propagation effects on indirect dark matter searches
Ignacio MartÃnez López, Rafael Alves Batista, Miguel A. Sánchez-Conde +1
In this work, we investigate dark matter (DM) detection in the context of weakly interacting massive particles (WIMPs). Upon annihilation, WIMPs generate cascades of secondary part…
CRPropa 3.3: Toward a Unified Multi-Messenger Framework from GeV to ZeV Energies
Sophie Aerdker, Rafael Alves Batista, Julia Becker Tjus +11
We present CRPropa 3.3, the latest release of the publicly available Monte Carlo framework for simulating the propagation of high-energy particles in astrophysical environments. Th…
Spectra for the Vacuum Cherenkov Effect in Astrophysical Electromagnetic Cascades with Lorentz Invariance Violation
Andrey Saveliev, Rafael Alves Batista, Feodor Mishin
Lorentz invariance violation is a feature of several quantum gravity models in which Lorentz symmetry is broken at high energies, possibly leading to changes in particle behavior a…
Effects of extragalactic magnetic field on the spectra of ultra-high-energy cosmic rays from jetted sources
Sarah Soares Sippert, Carlos Magno R. da Costa, Rogerio M. de Almeida +2
The origins and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) are unknown. Many models attribute their extreme energies to powerful astrophysical jets. Understa…
