Astronomical bounds on a future Big Freeze singularity
It was recently found that dark energy in the form of phantom generalized Chaplygin gas may lead to a new form of a cosmic doomsday, the Big Freeze singularity. Like the Big Rip singularity, the Big
Cosmic anisotropic doomsday in Bianchi type I universes
In this paper we study finite time future singularities in anisotropic Bianchi type I models. It is shown that there exist future singularities similar to Big Rip ones (which appear in the framework
Classical and quantum fate of the little sibling of the big rip in f(R) cosmology
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 observable Universe
Little rip in classical and quantum f(R) cosmology
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 as a big rip
Is the accelerated expansion evidence of a forthcoming change of signature
We show that regular changes of signature on brane-worlds in AdS5 bulks may account for some types of the recently fashionable sudden singularities. Therefore, the fact that the Universe seems to
Phantom singularities and their quantum fate: general relativity and beyond—a CANTATA COST action topic
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. We review here the
Singularities in Inflationary Cosmological Models
Due to the accelerated expansion of the universe, the possibilities for the formation of singularities has changed from the classical Big Bang and Big Crunch singularities to include a number of new
Tradeoff between smoother and sooner “little rip”
There exist dark-energy models that predict the occurrence of a “little rip”. At the point of a little rip the Hubble rate and its cosmic time derivative approach infinity, which is quite similar to
Appeasing the phantom menace?
An induced gravity brane-world model is considered herein. A Gauss-Bonnet term is provided for the bulk, whereas phantom matter is present on the brane. It is shown that a combination of infra-red

Does the Big Rip survive quantization?
It is known that certain quantum cosmological models present quantum behavior for large scale factors. Since quantization can suppress past singularities, it is natural to inquire whether quantum
Properties of singularities in the (phantom) dark energy universe
The properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. We classify the finite-time singularities into four classes and
Quantum effects, soft singularities and the fate of the universe in a braneworld cosmology
We examine a class of braneworld models in which the expanding universe encounters a ‘quiescent’ future singularity. At a quiescent singularity, the energy density and pressure of the cosmic fluid as
Axion phantom energy
The existence of phantom energy in a universe which evolves to eventually show a big rip doomsday is a possibility which is not excluded by present observational constraints. In this paper it is
Escaping the big rip?
We discuss dark energy models which might describe effectively the actual acceleration of the universe. More precisely, for a four-dimensional Friedmann–Lemaître–Robertson–Walker (FLRW) universe we
Brane World States from a Generalized Chaplygin Gas
We consider the hypothesis that the transition to an accelerated period in the current universe involves a quantum mechanical process. We identify a minisuperspace configuration with two Lorentzian
Final state and thermodynamics of a dark energy universe
As it follows from the classical analysis, the typical final state of a dark energy universe where a dominant energy condition is violated is a finite-time, sudden future singularity (a big rip). For
Brane world cosmology
Recent developments in the physics of extra dimensions have opened up new avenues to test such theories. We review cosmological aspects of brane world scenarios such as the Randall–Sundrum brane
