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…
Gravitational Collapse via Wheeler-DeWitt Equation
Davide Batic, Marek Nowakowski
We analyze the Wheeler-DeWitt (WDW) equation in the context of a gravitational collapse. The physics of an expanding/collapsing universe and many details of a collapsing star can c…
New vistas on the Laplace-Runge-Lenz vector
Davide Batic, Marek Nowakowski, Aya Mohammad Abdelhaq
Scalar, vector and tensor conserved quantities are essential tools in solving different problems in physics and complex, nonlinear differential equations in mathematics. In many gu…
Relevant scales for the -metric with positive cosmological constant
Davide Batic, Hadeel Ali Kittaneh, Marek Nowakowski
In this work, we study the weak and strong gravitational lensing in the presence of an accelerating black hole in a universe with positive cosmological constant . First of all,…
New indefinite integrals of Heun functions
Davide Batic, Omar Forrest, Marek Nowakowski
We present a conspicuous number of indefinite integrals involving Heun functions and their products obtained by means of the Lagrangian formulation of a general homogeneous linear…
