Are we survivors of the sudden past singularity?
Adam Balcerzak, Tomasz Denkiewicz, Mateusz Lisaj
In this paper, we investigate the viability of cosmological models featuring a type II singularity that occurs during the past evolution of the Universe. We construct a scenario in…
A critical assessment of some inhomogeneous pressure Stephani models
Adam Balcerzak, Mariusz P. Dabrowski, Tomasz Denkiewicz +2
We consider spherically symmetric inhomogeneous pressure Stephani universes, the center of symmetry being our location. The main feature of these models is that comoving observers…
Exotic-singularity-driven dark energy
Mariusz P. Dabrowski, Tomasz Denkiewicz
We discuss various types of exotic (non-standard) singularities in the Universe: a Big-Rip (BR or type I), a Sudden Future Singularity (SFS or type II), a Generalized Sudden Future…
Barotropic index w-singularities in cosmology
Mariusz P. Dabrowski, Tomasz Denkiewicz
We find an explicit cosmological model which allows a special type of cosmological singularity which we call a -singularity. This singularity has the scale factor finite, the en…
