DOI: 10.1088/1361-6382/adbed1
Abstract: A set of temporal singularities (transients) in the mass-energy density and pressure, bearing a specific mathematical structure which represents a new solution to the continuity equation (i.e. conservation of mass-energy) and satisfying the strong energy… read more here.

Abstract: We consider two stable Interacting Dark Matter -- Dark Energy models and confront them against current Cosmic Microwave Background data from the \textit{Planck} satellite. We then generate luminosity distance measurements from ${\cal O}(10^3)$ mock Gravitational… read more here.

DOI: 10.1088/1475-7516/2024/09/076
Abstract: The description of dark matter as a pressure-less fluid and of dark energy as a cosmological constant, both minimally coupled to gravity, constitutes the basis of the concordance ΛCDM model. However, the concordance model is… read more here.

Abstract: Forty years ago Witten suggested that dark matter could be composed of macroscopic clusters of strange quark matter. This idea was very popular for several years, but it dropped out of fashion once lattice QCD… read more here.

DOI: 10.1103/lq8t-gw3m
Abstract: In recent years, the interaction between dark matter (DM) and dark energy (DE) has become a topic of interest in cosmology. Interacting dark matter-dark energy (IDE) models have a substantial impact on the formation of… read more here.

DOI: 10.1103/physrevd.104.103513
Abstract: Two models that unify warm inflation with dark matter and dark energy are proposed. In the models, a single scalar field is responsible for the early expansion of the universe through the process of dissipative… read more here.
