Dark sector unifications: Dark matter-phantom energy, dark matter - constant w dark energy, dark matter-dark energy-dark matter [PDF]
The paper brings a novel approach to unification of dark matter and dark energy in terms of a cosmic fluid. A model is introduced in which the cosmic fluid speed of sound squared is defined as a function of its equation of state (EoS) parameter.

Evidence for Dark Energy Driven by Star Formation: Information Dark Energy? [PDF]
Evidence is presented for dark energy resulting directly from star formation. A survey of stellar mass density measurements, SMD(a), as a function of universe scale size a, was found to be described by a simple CPL w0 − wa parameterisation that was in ...

Information Dark Energy Can Resolve the Hubble Tension and Is Falsifiable by Experiment [PDF]
We consider the role information energy can play as a source of dark energy. Firstly, we note that if stars and structure had not formed in the universe, elemental bits of information describing the attributes of particles would have exhibited properties

We build a model of metastable dark energy, in which the observed vacuum energy is the value of the scalar potential at the false vacuum. The scalar potential is given by a sum of even self-interactions up to order six.

Early dark energy from the dark energy-dark matter interaction [PDF]
In this paper we propose a dark energy-dark matter interaction model in which an early dark energy phase emerges. This model is unique since the usual interacting dark matter-energy models affect the late time cosmology and not the early phase ...

Dark energy models account for the present accelerated expansion of the universe. Many models were suggested and investigated, based on very different physical principles. We will review some representative models emphasizing similarities and differences between these various approaches.

Combining outlier analysis algorithms to identify new physics at the LHC
The lack of evidence for new physics at the Large Hadron Collider so far has prompted the development of model-independent search techniques. In this study, we compare the anomaly scores of a variety of anomaly detection techniques: an isolation forest ...

290 metagenome-assembled genomes from the Mediterranean Sea: a resource for marine microbiology [PDF]
The Tara Oceans Expedition has provided large, publicly-accessible microbial metagenomic datasets from a circumnavigation of the globe. Utilizing several size fractions from the samples originating in the Mediterranean Sea, we have used current assembly ...

Constrains on the electric charges of the binary black holes with GWTC-1 events
Testing black hole’s charged property is a fascinating topic in modified gravity and black hole astrophysics. In the first Gravitational-Wave Transient Catalog (GWTC-1), ten binary black hole merger events have been formally reported, and these ...
