Muon Imaging of Hydrotreatment Reactors
Rafael Armando Martínez-Rivero, Christian Sarmiento-Cano, Diego Catillo-Morales +4
This study presents the design and simulation-based validation of a muon imaging system tailored for potential applications in industrial hydrotreatment units. The system is built…
Poststack Seismic Data Preconditioning via Dynamic Guided Learning
Javier Torres-Quintero, Paul Goyes-Peñafiel, Ana Mantilla-Dulcey +3
Seismic data preconditioning is essential for subsurface interpretation. It enhances signal quality while attenuating noise, improving the accuracy of geophysical tasks that would…
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…
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…
Design and construction of MuTe: a hybrid Muon Telescope to study Colombian Volcanoes
J. Peña-Rodríguez, J. Pisco-Guabave, D. Sierra-Porta +6
We present a hybrid Muon Telescope, MuTe, designed and built for imaging active Colombian volcanoes. The MuTe has a resolution of tens of meters, low power consumption, robustness…
Simulated Response of MuTe, a Hybrid Muon Telescope
A. Vásquez-Ramírez, M. Suárez-Durán, A. Jaimes-Motta +6
In this paper we present a complete and detailed computational model of the response of the hybrid Muon Telescope (MuTe), designed to perform muography volcanic studies. This instr…
Calibration and first measurements of MuTe: a hybrid Muon Telescope for geological structures
Jesús Peña-Rodríguez, Adriana Vásquez-Ramírez, José D. Sanabria-Gómez +3
In this work, we describe the calibration and first measurements in the commissioning of MuTe, a hybrid Muon Telescope with two subdetectors --a scintillator hodoscope and a Water…
Muon Tomography sites for Colombian volcanoes
A. Vesga-Ramírez, D. Sierra-Porta, J. Pena-Rodriguez +6
By using a very detailed simulation scheme, we have calculated the cosmic ray background flux at 13 active Colombian volcanoes and developed a methodology to identify the most conv…
Astroparticle Techniques: Colombia active volcano candidates for Muon Telescope observation sites
H. Asorey, A. Balaguera-Rojas, L. A. Núñez +5
We discuss a methodology to identify observation points for muongraphy of active Colombian Volcanoes and it is found that only Cerro Machin can be studied.
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +447
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Au…
Geodesic motion in a stationary dihole spacetime
F. L. Dubeibe, José D. Sanabria-Gómez
The knowledge of the properties of the different exact solutions modeling binary systems, is a necessary step towards the classification of physically suitable solutions and its co…
Comment on "Generalized black diholes"
V. S. Manko, J. D. Sanabria-Gómez
We show that a recent solution published by Cabrera-Munguia et al. is physically inconsistent since the quantity it involves does not have a correct limit .
Stationary black diholes
V. S. Manko, R. I. Rabadán, J. D. Sanabria-Gómez
In this paper we present and analyze the simplest physically meaningful model for stationary black diholes - a binary configuration of counter-rotating Kerr-Newman black holes endo…
Innermost stable circular orbits around magnetized rotating massive stars
José D. Sanabria-Gómez, José L. Hernández-Pastora, F. L. Dubeibe
In 1998, Shibata and Sasaki [Phys. Rev. D 58, 104011 (1998)] presented an approximate analytical formula for the radius of the innermost stable circular orbit (ISCO) of a neutral t…
Chaotic dynamics around astrophysical objects with nonisotropic stresses
F. L. Dubeibe, Leonardo A. Pachon, Jose D. Sanabria-Gomez
The existence of chaotic behavior for the geodesics of the test particles orbiting compact objects is a subject of much current research. Some years ago, Guéron and Letelier [Phys.…
The double-Kerr equilibrium configurations involving one extreme object
J. A. Rueda, V. S. Manko, E. Ruiz +1
We demonstrate the existence of equilibrium states in the limiting cases of the double-Kerr solution when one of the constituents is an extreme object. In the `extreme-subextreme'…
