Inhomogeneous solutions in gravity
Sebastián Nájera, Aram Aguilar, Geovanny A. Rave-Franco +2
In this paper we explore the possibility to find exact solutions for Teleparallel Gravity (TG) of the type of spherically symmetric Lema\^ıtre-Tolman-Bondi (LTB) dust models. We ap…
The first non-static inhomogeneous exact solution in gravity
Sebastián Nájera, Aram Aguilar, Celia Escamilla-Rivera +1
We examine in this paper the possibility of finding exact solutions for Teleparallel Gravity (TG) of the type of spherically symmetric Lema\^ıtre-Tolman-Bondi (LTB) dust models. We…
On Negative Mass Cosmology in General Relativity
Sebastián Nájera, Aldo Gamboa, Alejandro Aguilar-Nieto +1
In this Letter we present strong arguments in favour of thoroughly revising the negative mass cosmology (NMC), which has been proposed as a simple alternative explanation of dark e…
Non-comoving Cold Dark Matter in a CDM background
Sebastián Nájera, Roberto A. Sussman
We examine the evolution of peculiar velocities of cold dark matter (CDM) in localized arrays of inhomogeneous cosmic structures in a CDM background that can be identified as a…
