Cascades from ultra-high-energy neutrinos
Gaetano Di Marco, Rhorry Gauld, Rafael Alves Batista +2
Neutrinos produced at the highest energies can interact with cosmic neutrino and radiation backgrounds during their propagation to Earth. The many available , , and $νγ…
Cosmic Ray Diffusion and the Origin of Very High Energy Gamma-Ray Emission in Young Massive Stellar Clusters
Lucas Barreto-Mota, Elisabete M. de Gouveia Dal Pino, Gaetano Di Marco +2
The search for Galactic sources capable of accelerating cosmic rays (CRs) to PeV energies has advanced significantly in recent years. High-energy observatories such as LHAASO have…
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…
The impact of gamma-ray propagation effects on indirect dark matter searches
Ignacio Martínez 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…
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}…
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…
The Quest for the Origins of Ultra-High-Energy Cosmic Rays
Rafael Alves Batista
Significant progress has been made over the past decades towards unveiling the sources of the most energetic particles in nature, the ultra-high-energy cosmic rays (UHECRs). Despit…
Revisiting the propagation of highly-energetic gamma rays in the Galaxy
Gaetano Di Marco, Rafael Alves Batista, Miguel Ángel Sánchez-Conde
Recent gamma-ray observations have detected photons up to energies of a few PeV. These highly energetic gamma rays are emitted by the most powerful sources in the Galaxy. Propagati…
High-Energy Neutrino Production in Clusters of Galaxies
Saqib Hussain, Rafael Alves Batista, Elisabete de Gouveia Dal Pino +1
In this work, we compute the contribution from clusters of galaxies to the diffuse neutrino background. Clusters of galaxies can potentially produce cosmic rays (CRs) up to very-hi…
High-Energy Neutrino Production in Clusters of Galaxies
Saqib Hussain, Rafael Alves Batista, Elisabete M. de Gouveia Dal Pino +1
Clusters of galaxies can potentially produce cosmic rays (CRs) up to very-high energies via large-scale shocks and turbulent acceleration. Due to their unique magnetic-field config…
