Vacíos cósmicos como laboratorios cosmológicos
(2021)
Los extensos vacíos cósmicos (voids) presentes en la estructura a gran escala del Universo constituyen sistemas físicos ideales para estudiar el fenómeno de la energía oscura, uno de los misterios fundamentales de la ...
Análisis numérico de ecuaciones force-free en potenciales de Euler
(2021-04)
En este trabajo se presenta un estudio numérico de las ecuaciones de Force-Free en Potenciales de Euler las cuales conforman un sistema de ecuaciones mal puesto o débilmente hiperbólico. Esta característica da lugar a la ...
Hydrostatic equilibrium preservation in MHD numerical simulation with stratified atmospheres: Explicit Godunov-type schemes with MUSCL reconstruction
(EDP Sciences, 2019-11)
Many astrophysical processes involving plasma flows are produced in the context of a gravitationally stratified atmosphere in hydrostatic equilibrium, in which strong gradients can exist with gas properties that vary in ...

Simulações de ram pressure em aglomerados de galáxias
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Física e AstronomiaUTFPR, 2022-10-19)
Numerical simulations are an excellent tool to study astrophysical phenomena, considering the huge scales of time and space in which they occur. Ram pressure is an effect that galaxies crossing the intracluster medium (ICM) ...
Efecto de lente gravitacional unificado: una aproximación a la reconstrucción del perfil de masa de un cúmulo galáctico
(Bogotá - Ciencias - Maestría en Ciencias - AstronomíaUniversidad Nacional de Colombia - Sede Bogotá, 2020-10-28)
In this work, we present the description, implementation, and application of a free-form reconstruction method that makes use of the gravitational lensing effect to produce an estimation of the mass profile of a galaxy ...
Super massive black holes in star forming gaseous circumnuclear discs
(2015)
Using Nbody/SPH simulations we study the evolution of the separation of a pair of SMBHs
embedded in a star forming circumnuclear disk (CNDa). This type of disk is expected to be formed
in the central kilo parsec of the ...
