Multi epoch spectroscopic variability of the B supergiant HD75149
J. Chamoun-Contreras, C. Arcos, N. Machuca +6
Massive stars continuously enrich the surrounding interstellar medium by supplying it with stellar material driven by their powerful winds. B supergiant stars (BSGs) in particular…
Novel five-dimensional rotating Lifshitz black holes with electric and axionic charges
Moisés Bravo-Gaete, Jhony A. Herrera-Mendoza, Julio Oliva +1
In this work, we construct a new family of exact five-dimensional charged and rotating asymptotically Lifshitz black holes. The spacetime solves Einstein equations coupled to a dil…
Intrinsic Resonance depends on Network Size of Coupled-Delayed Interacting Oscillators
Felipe A. Torres, Alejandro Weinstein, Jesus M. Cortes +1
The collective frequency that emerges from synchronized neuronal populations--the network resonance--shows a systematic relationship with brain size: whole-brain's large networks o…
Implementation of a Fuzzy Relational Database. Case Study: Chilean Cardboard Industry in the Maule Region
Leoncio Jimenez, Angélica Urrutia, José Galindo +1
The international database community refers to the manipulation of data with inaccuracy and uncertainty using the term fuzzy, which has been translated into Spanish as "borroso" an…
Thermodynamic and observational constraints on black holes with primary hair in Beyond Horndeski Gravity: Stability and shadows
Cristian Erices, Mohsen Fathi
In this paper, we find that unlike in General Relativity, the shift-symmetric subclass of Beyond Horndeski theories permits black holes with primary hair that are thermodynamically…
Quasinormal modes, greybody factors and thermodynamics of four dimensional AdS black holes in Critical Gravity
Jianhui Lin, Moisés Bravo-Gaete, Xiangdong Zhang
In the present work, considering critical gravity as a gravity model, an electrically charged topological Anti-de Sitter black hole with a matter source characterized by a nonlinea…
Magnetized AdS/BCFT Correspondence in Horndeski Gravity
Fabiano F. Santos, Moisés Bravo-Gaete, Manoel M. Ferreira +1
This work examines the thermodynamics and hydrodynamics behaviors of a five-dimensional black hole under the influence of an external magnetic field. The solution is the gravity du…
Stealth Ellis Wormholes In Horndeski theories
Athanasios Bakopoulos, Nikos Chatzifotis, Cristian Erices +1
In this work we are revisiting the well studied Ellis wormhole solution in a generalized Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fun…
Exploring the shear viscosity in four-dimensional planar black holes beyond General Relativity
Moisés Bravo-Gaete, Luis Guajardo, Fabiano F. Santos
The well known shear viscosity to entropy density ratio () cannot be computed when the black hole space-time has zero thermodynamic entropy. This is the case, for example, whe…
Revisiting Fractional Cosmology
Bayron Micolta-Riascos, Alfredo D. Millano, Genly Leon +2
Recently, the research community has been exploring fractional calculus to address problems related to cosmology; in this approach, the gravitational action integral is altered, le…
AdS/BCFT correspondence and Horndeski gravity in the presence of gauge fields: holographic paramagnetism/ferromagnetism phase transition
Fabiano F. Santos, Moisés Bravo-Gaete, Oleksii Sokoliuk +1
This paper presents a dual gravity model for a (2+1)-dimensional system with a limit on finite charge density and temperature, which will be used to study the properties of the hol…
Towards the Generation of Synthetic Images of Palm Vein Patterns: A Review
Edwin H. Salazar-Jurado, Ruber Hernández-García, Karina Vilches-Ponce +3
With the recent success of computer vision and deep learning, remarkable progress has been achieved on automatic personal recognition using vein biometrics. However, collecting lar…
Visualisation of matrix product: Using light to clarify an abstract mathematical concept
Jorge Pinochet, Walter Bussenius Cortada
Teaching the noncommutativity of the product of matrices to high school or college level students is a difficult task when approached from a purely formal perspective. The aim of t…

Moisés Bravo-Gaete, Luis Guajardo, Julio Oliva
In this work, we consider the recently proposed well-defined theory that permits a healthy limit of the Einstein-Gauss-Bonnet combination, which requires the addition of a…
