Black hole thermodynamics from logotropic fluids
Salvatore Capozziello, Rocco D'Agostino, Alessio Lapponi +1
We show that the Einstein field equations with a negative cosmological constant can admit black hole solutions whose thermodynamics coincides with that of logotropic fluids, recent…
The phase-space view of non-local gravity cosmology
Salvatore Capozziello, Rocco D'Agostino, Orlando Luongo
We consider non-local Integral Kernel Theories of Gravity in a homogeneous and isotropic universe background as a possible scenario to drive the cosmic history. In particular, we i…
Healing the cosmological constant problem during inflation through a unified quasi-quintessence matter field
Rocco D'Agostino, Orlando Luongo, Marco Muccino
We heal the cosmological constant problem by means of a \emph{cancellation mechanism} that adopts a phase transition during which quantum fluctuations are eliminated. To this purpo…
Constraining primordial black holes as a fraction of dark matter through accretion disk luminosity
Rocco D'Agostino, Roberto Giambò, Orlando Luongo
In this paper, we consider the hypothesis that fractions of dark matter could be constituted by primordial black holes (PBHs). To test this possibility, we work out the observation…
Thermodynamic parametrization of dark energy
Salvatore Capozziello, Rocco D'Agostino, Orlando Luongo
We propose a model-independent parametrization of dark energy motivated by thermodynamics. To this aim, we consider Padé polynomials to reconstruct the form of deceleration paramet…
