Acceptability Conditions and Relativistic Barotropic Equations of State
Héctor Hernández, Daniel Suárez-Urango, Luis A. Núñez
We sketch an algorithm to generate exact anisotropic solutions starting from a barotropic EoS and setting an ansatz on the metric functions. To illustrate the method, we use a gene…
Modeling and simulation of the R5912 photomultiplier for the LAGO project
S. Hernández-Barajas, Y. León-Carreño, J. Peña-Rodríguez +2
We present the results of modeling and simulating the Hamamatsu R5912 photomultiplier tube that is used in most of the sites of the Latin American Giant Observatory (LAGO). The mod…
Measurement of the cosmic-ray energy spectrum above eV using the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +380
We report a measurement of the energy spectrum of cosmic rays for energies above eV based on 215,030 events recorded with zenith angles below . A k…
Impact of Global Data Assimilation System atmospheric models on astroparticle showers
Jennifer Grisales-Casadiegos, Christian Sarmiento-Cano, Luis A. Núñez +1
We present a methodology to simulate the impact of the atmospheric models in the background particle flux on ground detectors using the Global Data Assimilation System. The methodo…
Simulated Annealing for Volcano Muography
A. Vesga-Ramírez, J. D. Sanabria-Gómez, D. Sierra-Porta +5
Muography or muon radiography is a non-invasive emerging image technology relying on high energy atmospheric muons, which complements other standard geophysical tools to understand…
sPad of Super Accuracy and Geometry in Old Babylon. -- sPad de Súper Exactitud y Geometría en la Antigua Babilonia
F. Quiñonez, L. A. Núñez, F. D. Lora-Clavijo +3
Recently it has been discovered that on a stone tablet over 3800 years old, the Plimpton-322 table, are carved the geometric relations that exist between the sides of 15 right tria…
