On regular charged black holes in three dimensions
Pablo Bueno, Oscar Lasso Andino, Javier Moreno +1
As argued in arXiv:2104.10172, introducing a non-minimally coupled scalar field, three-dimensional Einstein gravity can be extended by infinite families of theories which admit sim…
Massive particle surfaces and black hole shadows from intrinsic curvature
Boris Bermúdez-Cárdenas, Oscar Lasso Andino
In a recent article PRD 111, 064001 (2025) a new geometric a approach for studying massive particle surfaces was proposed. Using the Gaussian and geodesic curvatures of a two dimen…
Massive particle surfaces, partial umbilicity and circular orbits
Boris Bermúdez-Cárdenas, Oscar Lasso Andino
The generalization of photon spheres by considering the trajectories of massive particles leads to the definition of Massive Particle Surfaces (MPS). These surfaces are built with…
Attitudes Towards Migration in a COVID-19 Context: Testing a Behavioral Immune System Hypothesis with Twitter Data
Yerka Freire-Vidal, Gabriela Fajardo, Carlos Rodríguez-Sickert +3
The COVID-19 outbreak implied many changes in the daily life of most of the world's population for a long time, prompting severe restrictions on sociality. The Behavioral Immune Sy…
Studying a precessing jet of a massive young stellar object within a chemically rich region
S. Paron, D. Mast, C. Fariña +4
In addition to the large surveys and catalogs of massive young stellar objects and outflows, dedicated studies of particular sources, in which high-angular observations (mainly at…
Regular black holes and its thermodynamics in Lovelock gravity
Rodrigo Aros, Milko Estrada
In this work two new families of non-singular or regular black hole solutions are displayed. These black holes behave as de Sitter space near its center and have a well defined AdS…
