Observational constraints on cosmological future singularities

Understand

In this work we consider a family of cosmological models featuring future singularities.

• This type of cosmological evolution is typical of dark energy models with an equation of state violating some of the standard energy conditions (e.g.
• the null energy condition).
• Such kind of behavior, widely studied in the literature, may arise in cosmologies with phantom fields, theories of modified gravity or models with interacting dark matter/dark energy.
