Ripped {\Lambda}CDM: an observational contender to the consensus cosmological model

Understand

Current observations do not rule out the possibility that the Universe might end up in an abrupt event.

• Different such scenarios may be explored through suitable parameterizations of the dark energy and then confronted to cosmological background data.
• Here we parameterize a pseudorip scenario using a particular sigmoid function and carry an in-depth multifaceted examination of its evolutionary features and statistical performance.
• This depiction of a non violent final fate of our cosmos seems to be arguably statistically favoured over the consensus {\Lambda}CDM model according to some Bayesian discriminators.
