Classical and quantum cosmology: The big rip, the little rip and the little sibling of the big rip
Teodor Borislavov Vasilev, Mariam Bouhmadi-López, Prado Martín-Moruno
The big rip, the little rip and the little sibling of the big rip are cosmological doomsdays predicted by some phantom dark energy models that could describe the future evolution o…
Modified Gravity and Cosmology: An Update by the CANTATA Network
Emmanuel N. Saridakis, Ruth Lazkoz, Vincenzo Salzano +50
General Relativity and the CDM framework are currently the standard lore and constitute the concordance paradigm. Nevertheless, long-standing open theoretical issues, as well as…
The little rip in classical and quantum cosmology
Teodor Borislavov Vasilev, Mariam Bouhmadi-López, Prado Martín-Moruno
The little rip is a cosmological abrupt event predicted by some phantom dark energy models that could describe the future evolution of our Universe. This event can be interpreted a…
The classical and quantum fate of the Little Sibling of the Big Rip in cosmology
Teodor Borislavov Vasilev, Mariam Bouhmadi-López, Prado Martín-Moruno
The Little Sibling of the Big Rip is a cosmological abrupt event predicted by some phantom cosmological models that could describe our Universe. When this event is approached the o…
The type III stress-energy tensor: Ugly Duckling of the Hawking-Ellis classification
Prado Martín-Moruno, Matt Visser
We present some advances in the understanding of type III stress-energy tensors as per the Hawking-Ellis classification. Type I and type II naturally appear in classical situations…
Phantom singularities and their quantum fate: general relativity and beyond
Mariam Bouhmadi-López, Claus Kiefer, Prado Martín-Moruno
Cosmological observations allow the possibility that dark energy is caused by phantom fields. These fields typically lead to the occurrence of singularities in the late Universe. W…
Generalized Rainich conditions, generalized stress-energy conditions, and the Hawking-Ellis classification
Prado Martín-Moruno, Matt Visser
The (generalized) Rainich conditions are algebraic conditions which are polynomial in the (mixed-component) stress-energy tensor. As such they are logically distinct from the usual…
Cosmology with moving bimetric fluids
Carlos García-García, Antonio L. Maroto, Prado Martín-Moruno
We study cosmological implications of bigravity and massive gravity solutions with non-simultaneously diagonal metrics by considering the generalized Gordon and Kerr-Schild ansatze…
A novel approach to thin-shell wormholes and applications
Francisco S. N. Lobo, Mariam Bouhmadi-López, Prado Martín-Moruno +2
A novel framework is presented that can be adapted to a wide class of generic spherically symmetric thin-shell wormholes. By using the Darmois--Israel formalism, we analyze the sta…
Novel stability approach of thin-shell gravastars
Francisco S. N. Lobo, Prado Martín-Moruno, Nadiezhda Montelongo-García +1
We develop an extremely general and robust framework that can be adapted to wide classes of generic spherically symmetric thin-shell gravastars. The thin shell (transition layer) w…
Isotropic extensions of the vacuum solutions in general relativity
C. Molina, Prado Martín-Moruno, Pedro F. González-Díaz
In this work, we obtain isotropic extensions of the usual spherically symmetric vacuum geometries in general relativity. Exact and perturbative solutions are derived. The classes o…
On accretion of dark energy onto black- and worm-holes
José A. Jiménez Madrid, Prado Martín-Moruno
We review some of the possible models that are able to describe the current Universe which point out the future singularities that could appear. We show that the study of the dark…
