Assessing the foundation and applicability of some dark energy fluid models in the Dirac-Born-Infeld framework
Muhsin Aljaf, Daniele Gregoris, Martiros Khurshudyan
In this paper, we will deepen the understanding of some fluid models proposed by other authors for the description of dark energy. Specifically, we will show that the so-called (Mo…
Observational backreaction in discrete black holes lattice cosmological models
Daniele Gregoris, Kjell Rosquist
Applying the Sachs formalism, the optical properties encoded in the distance modulus are studied along curves exhibiting local rotational symmetry for some closed inhomogeneous cos…
Constraints on interacting dark energy models through cosmic chronometers and Gaussian process
Muhsin Aljaf, Daniele Gregoris, Martiros Khurshudyan
In this paper, after reconstructing the redshift evolution of the Hubble function by adopting Gaussian process techniques, we estimate the best-fit parameters for some flat Friedma…
Thermodynamics of Shearing Massless Scalar Field Spacetimes is Inconsistent With the Weyl Curvature Hypothesis
Daniele Gregoris, Yen Chin Ong, Bin Wang
Our Universe has an arrow of time. In accordance with the second law of thermodynamics, entropy has been increasing ever since the Big Bang. The fact that matter is in thermal equi…
On the Curvature Invariants of the Massive Banados-Teitelboim-Zanelli Black Holes and Their Holographic Pictures
Mahdis Ghodrati, Daniele Gregoris
In this paper, the curvature structure of a (2+1)-dimensional black hole in the massive-charged-Born-Infeld gravity is investigated. The metric that we consider is characterized by…
Black holes and naked singularities from Anton-Schmidt's fluids
Salvatore Capozziello, Rocco D'Agostino, Daniele Gregoris
Adopting the Tolman-Oppenheimer-Volkoff formalism, we propose a new analytical solution for a static and spherically symmetric black hole where the cosmological constant is general…
