The Microwave Air Yield Beam Experiment (MAYBE): measurement of GHz radiation for Ultra-High Energy Cosmic Rays detection [PDF]

open access: green, 2011
We present first measurements by MAYBE of microwave emission from an electron beam induced air plasma, performed at the electron Van de Graaff facility of the Argonne National Laboratory. Coherent radio Cherenkov, a major background in a previous beam experiment, is not produced by the 3 MeV beam, which simplifies the interpretation of the data.

Coherence length of cosmic background radiation enlarges the attenuation length of the ultra-high energy proton [PDF]

open access: green, 2008
It is pointed out that an agreement of the one particle energy spectrum of the cosmic background radiation (CMBR) with Plank distribution of 2.725 [K] does not give a strong constraint on the coherence length of CMBR if the mean free path of CMBR is very long. The coherence length in this situation is estimated as a few times of $k_BT$.

Astrophysical neutrino production and impact of associated uncertainties in photo-hadronic interactions of UHECRs [PDF]

open access: yesEPJ Web of Conferences, 2019
High energy neutrinos can be produced by interactions of ultra-high energy cosmic rays (UHECRs) in the dense radiation fields of their sources as well as off the cosmic backgrounds when they propagate through the universe. Multi-messenger interpretations

Composición de la radiación cósmica de ultra-alta energía a partir de los datos del Observatorio Pierre Auger (Composition of ultra-high energy cosmic radiation from the Pierre Auger Observatory data) [PDF]

open access: closed, 2011
Aunque el descubrimiento de los rayos cósmicos se produjo hace casi cien años, algunas de sus propiedades más importantes, como el origen, mecanismos de producción o composición en masa, son aún un misterio. Actualmente el conocimiento de los rayos cósmicos de baja energía es muy amplio, pero a energías superiores el desconocimiento es cada vez ...

Treasure Maps for Detections of Extreme Energy Cosmic Rays

open access: yesThe Astrophysical Journal, 2023
The origin of ultra-high-energy cosmic rays is a 60 yr old mystery. We show that with more events at the highest energies (above 150 EeV) it may be possible to limit the character of the sources and learn about the intervening magnetic fields. Individual
