Regular Cosmologies: Three Distinct Routes
Sergio Bravo Medina, Marek Nowakowski
Regular black holes avoid the central singularity by replacing it with a de Sitter core. We ask what cosmology follows if the same idea is brought to the early universe. Regular me…
The Universe according to DESI results
Davide Batic, Sergio Bravo Medina, Marek Nowakowski
The recent fit of cosmological parameters by the Dark Energy Spectroscopic Instrument (DESI) collaboration will have a significant impact on our understanding of the universe. Give…
Cosmologies in theory with non-minimal coupling between geometry and matter
Sergio Bravo Medina, Marek Nowakowski, Ronaldo V. Lobato +1
Among the recent extensions to standard General Relativity, gravity has risen an interest given the possibility of coupling between geometry and matter. We exa…
Non-singular non-flat universes
Andres Felipe Estupinan Salamanca, Sergio Bravo Medina, Marek Nowakowski +1
The quest to understand better the nature of the initial cosmological singularity is with us since the discovery of the expanding universe. Here, we propose several non-flat models…
Quantum Mechanical Corrections to the Schwarzschild Black Hole Metric
P. Bargueño, S. Bravo Medina, M. Nowakowski +1
Motivated by quantum mechanical corrections to the Newtonian potential, which can be translated into an -correction to the component of the Schwarzschild metric, we…
The Dirac equation in the Kerr-de Sitter metric
D. Batic, K. Morgan, M. Nowakowski +1
We consider a fermion in the presence of a rotating black hole immersed in a universe with positive cosmological constant. After deriving new formulae for the event, Cauchy and cos…
