Investigating Dark Energy Equation of State With High Redshift Hubble Diagram
Marek Demianski, Elisabeta Lusso, Maurizio Paolillo +2
Several independent cosmological data, collected within the last twenty years, revealed the accelerated expansion rate of the Universe, usually assumed to be driven by the so calle…
Prospects of high redshift constraints on dark energy models with the Ep- Eiso correlation in long Gamma Ray Bursts
M. Demianski, E. Piedipalumbo, D. Sawant +1
So far large and different data sets revealed the accelerated expansion rate of the Universe, which is usually explained in terms of dark energy. The nature of dark energy is not y…
Observational tests of the Glavan, Prokopec and Starobinsky model of dark energy
Marek Demianski, Ester Piedipalumbo
In the last dozens of years different data sets revealed the accelerated expansion of the Universe which is driven by the so called dark energy, that now dominates the total amount…
High redshift constraints on dark energy models from the -- correlation in GRBs
Marek Demianski, Ester Piedipalumbo, Disha Sawant +1
Here we test different models of dark energy beyond the standard cosmological constant scenario. We start considering the CPL parameterization of the equation of state (EOS), then…
Cosmology with gamma-ray bursts: I. The Hubble diagram through the calibrated - correlation
Marek Demianski, Ester Piedipalumbo, Disha Sawant +1
Gamma-ray bursts are the most energetic explosions in the Universe. They are detectable up to very high redshifts, therefore can be used to study the expansion rate of the Universe…
Cosmology with gamma-ray bursts: II Cosmography challenges and cosmological scenarios for the accelerated Universe
Marek Demianski, Ester Piedipalumbo, Disha Sawant +1
Context. Explaining the accelerated expansion of the Universe is one of the fundamental challenges in physics today. Cosmography provides information about the evolution of the uni…
