Acceptability Conditions and Relativistic Anisotropic Generalized Polytropes

Daniel Suárez-Urango, J. Ospino, Héctor Hernández +1

This paper explored the physical acceptability conditions for anisotropic matter configurations in General Relativity. The study considered a generalized polytropic equation of sta…

Characterization of the muography background using the Muon Telescope (MuTe)

Jesús Peña-Rodríguez, Luis A. Núñez, Hernán Asorey

In this work, we estimate the background components in muography using the MuTe: a hybrid muon telescope composed of two subdetectors -a scintillator hodoscope and a Water Cherenko…

Systematic effects on the diversity of dwarf galaxies rotation curves

J. M. Pacheco-Arias, C. R. Carvajal-Bohorquez, Juan C. B. Pineda +1

Cosmological simulations of structure formation are invaluable to study the evolution of the Universe and the development of galaxies in it successfully reproducing many observatio…

Measurement of the fluctuations in the number of muons in extensive air showers with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +365

We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuation…

Radiating jump conditions in General Relativity

L. F Castañeda-Godoy, J. Ospino, L. A. Núñez

We present a unified description of spherical discontinuity surfaces in General Relativity based on two parameters: mass function and surface permeability. The surfaces considered…

Relativistic Anisotropic Polytropic Spheres: Physical Acceptability

D. Suárez-Urango, L. A. Núñez, H. Hernández

In this work we evaluate the physical acceptability of relativistic anisotropic spheres modeled by two polytropic equations of state -- with the same newtonian limit -- commonly us…

Physical acceptability conditions for realistic neutron star equations of state

D. Ramos-Salamanca, L. A. Núñez, J. Ospino

We select 37 most common and realistic dense matter equation of states to integrate the general relativistic stellar structure equations for static spherically symmetric matter con…
