Indications of a Late-Time Transition to a Strongly Interacting Dark Sector
Andronikos Paliathanasis
We explore the transition from the CDM to an interacting dark sector by introducing a model with a redshift threshold that controls the onset of the energy transfer between the…
Constraints on Chiral-Quintom dark energy after DESI DR2 and impact on unifying dark energy with inflation
Andronikos Paliathanasis, Tommaso Mengoni, Genly Leon +1
The recent data release DR2 from the Dark Energy Spectroscopic Instrument (DESI) has reinforced compelling evidence supporting the dynamical nature of dark energy. In this respect,…
Late-Time Cosmological Constraints on Kaniadakis Holographic Dark Energy
Giuseppe Gaetano Luciano, Andronikos Paliathanasis
Kaniadakis Holographic Dark Energy is a one-parameter extension of the standard HDE framework, in which the horizon entropy is reformulated using Kaniadakis entropy. At the cosmolo…
Compartmentalization in the Dark Sector of the Universe after DESI DR2 BAO data
Marcel van der Westhuizen, David Figueruelo, Rethabile Thubisi +3
We consider a non-linear interaction between the dark matter and dark energy components of the universe. In particular, within the FLRW geometry, where dark matter is described by…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Dark Energy within the Generalized Uncertainty Principle in Light of DESI DR2
Andronikos Paliathanasis
In this study, we modify the CDM model by introducing a deformed algebra within the framework of the Generalized Uncertainty Principle (GUP). We formulate the modified Raychaudh…
