Beyond dynamical dark energy: the role of dark sector interactions after DESI DR2
Weiqiang Yang, Sibo Zhang, Supriya Pan +2
Recent DESI DR2 observations have renewed interest in extensions of the CDM cosmological model, particularly through indications of a time-varying dark energy equation of state.…
Unifying the Dark Sector with the New Generalized Chaplygin Gas: Observational Constraints
Abdulla Al Mamon, Andronikos Paliathanasis, Subhajit Saha
In light of recent cosmological observations, we examine a generalized Chaplygin gas model with a redshift-dependent exponent as a framework for describing the dark energy and dark…
Cosmo-PINN: A Physics-Informed Neural Network for Cosmological Reconstruction
Andronikos Paliathanasis
We introduce Cosmo-PINN, a Physics-Informed Neural Network for reconstruction of the cosmological theory. In this work we demonstrate the application of the Cosmo-PINN in the recon…
Saturation Mechanisms in the Interacting Dark Sector
Andronikos Paliathanasis, Kevin J. Duffy
We introduce a family of phenomenological cosmological models featuring an interacting dark sector modulated by a sparseness scale parameter, in order to describe the late-time acc…
Cosmological Constraints on the Generalized Uncertainty Principle from Redshift-Space Distortions
Andronikos Paliathanasis
We investigate the imprints of the Generalized Uncertainty Principle on cosmological scales by using redshift-space distortion measurements in combination with background cosmologi…
Testing the Coexistence of Dark Energy and Dark Matter with Late-time Observational Data
Shambel Sahlu, Andronikos Paliathanasis, Genly Leon +1
We investigate the viability of a cosmological scenario with interacting dark sector, which can describe the coexistence between dark energy and dark matter. The model possesses an…
