Cosmological implications of photon-flux upper limits at ultra-high energies in scenarios of Planckian-interacting massive particles for dark matter
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
Using the data of the Pierre Auger Observatory, we report on a search for signatures that would be suggestive of super-heavy particles decaying in the Galactic halo. From the lack…
Investigating Hadronic Interactions at Ultra-High Energies with the Pierre Auger Observatory
Isabel Goos, :, P. Abreu +374
The development of an extensive air shower depends not only on the nature of the primary ultra-high-energy cosmic ray but also on the properties of the hadronic interactions. For e…
A lightning monitoring system for studying transient phenomena in cosmic ray observatories
J. Peña-Rodríguez, P. Salgado-Meza, L. Flórez-Villegas +1
During thunderstorms, the atmospheric electric field can increase above hundreds of kV/m, causing an acceleration in the charged particles of secondary cosmic rays. Such an acceler…
RACIMO@Bucaramanga: A Citizen Science Project on Data Science and Climate Awareness
J. Peña-Rodríguez, P. A. Salgado-Meza, H. Asorey +4
This paper describes a collaborative experience to empower organized communities to produce, curate and disseminate environmental data. A particular emphasis is done on the descrip…
Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
Instantons, which are non-perturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give…
Muography in Colombia: simulation framework, instrumentation and data analysis
J. Peña-Rodríguez, A. Vesga-Ramírez, A. Vásquez-Ramírez +8
We present the Colombo-Argentinian Muography Program for studying inland Latin-American volcanoes. It describes the implementation of a simulation framework covering various factor…
Testing effects of Lorentz invariance violation in the propagation of astroparticles with the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374
Lorentz invariance violation (LIV) is often described by dispersion relations of the form with delta different based on particle type , with…
LA-CoNGA physics: an Open Science Collaboration in Advanced Physics between Latin-America and Europe
Jesús Peña-Rodríguez, Luis A. Núñez
LA-CoNGA physics (for Latin-American alliance for Capacity buildiNG in Advance physics) is an ERASMUS+ project aiming to support the modernization of university infrastructure and…
