No evidence for dynamical dark energy from the Combo correlation of GRBs
Marco Muccino, Massimo Della Valle, Luca Izzo +1
Recently, the Dark Energy Spectroscopic Instrument (DESI) collaboration has presented results indicating that dark energy may exhibit dynamical behavior. Calibrated gamma-ray burst…
Tightening Cosmological Constraints Within and Beyond CDM Using Gamma-Ray Bursts Calibrated with Type Ia Supernovae
Wei Hong, Luca Izzo, Massimo Della Valle +3
Context. Gamma-ray bursts (GRBs) reach redshifts beyond Type Ia supernovae (SNe Ia) and can extend distance measurements into the early Universe, but their use as distance indicato…
Investigating the cosmic distance duality relation with gamma-ray bursts
Anna Chiara Alfano, Carlo Cafaro, Salvatore Capozziello +2
Deviations from the so-called {\it cosmic distance duality relation} may result from systematic errors in distance measurements or, more interestingly, hint at new physics. Further…
Exploring the cosmic microwave background dipole direction using gamma-ray bursts
Orlando Luongo, Marco Muccino, Francesco Sorrenti
We search for dipole variations in the Hubble constant using gamma-ray burst (GRB) data, as such anisotropies may shed light on the Hubble tension. We employ the most recent…
Addressing the tension through matter with pressure and no early dark energy
Youri Carloni, Orlando Luongo, Marco Muccino
We propose that the Hubble tension arises due to an unaccounted additional component, that behaves as \emph{matter with pressure}. We demonstrate that this fluid remains subdominan…
Characterizing the equivalence between dark energy and radiation using gamma-ray bursts
Orlando Luongo, Marco Muccino
Differently from the equivalence time between either matter and radiation or dark energy and matter, the equivalence between dark energy and radiation occurs between two subdominan…
Determining from distance sum rule combining gamma-ray bursts with observational Hubble data and strong gravitational lensing
Orlando Luongo, Marco Muccino
Model-independent bounds on the Hubble constant are important to shed light on cosmological tensions. We work out a model-independent analysis based on the sum rule, which is…
Dark energy reconstructions combining BAO data with galaxy clusters and intermediate redshift catalogs
Orlando Luongo, Marco Muccino
Cosmological parameters and dark energy (DE) behavior are generally constrained assuming \textit{a priori} models. We work out a model-independent reconstruction to bound the key c…
Dark energy constraints using gamma-ray burst correlations with DESI 2024 data
Anna Chiara Alfano, Orlando Luongo, Marco Muccino
Even though the Dark Energy Spectroscopic Instrument (DESI) mission does not exclude a dynamical dark energy evolution, the concordance paradigm, i.e., the CDM model, remains st…
Cosmological constraints from calibrated gamma-ray burst correlation by using DESI 2024 data release
Anna Chiara Alfano, Orlando Luongo, Marco Muccino
Recent outcomes by the DESI Collaboration have shed light on a possible slightly evolving dark energy, challenging the standard CDM paradigm. To better understand dark energy na…
Does dark energy really revive using DESI 2024 data?
Youri Carloni, Orlando Luongo, Marco Muccino
We investigate the impact of the Dark Energy Spectroscopic Instrument (DESI) 2024 data on dark energy scenarios. We thus analyze three typologies of models, the first in which the…
Model independent cosmographic constraints from DESI 2024
Orlando Luongo, Marco Muccino
In this study, we explore model independent constraints on the universe kinematics up to the snap and jerk hierarchical terms. To do so, we consider the latest Baryon Acoustic Osci…
Cosmological transition epoch from gamma-ray burst correlations
Anna Chiara Alfano, Salvatore Capozziello, Orlando Luongo +1
The redshift and the jerk parameter of the transition epoch are constrained by using two model-independent approaches involving the direct expansion of the Hubble rate…
Breaking the baryon-dark matter degeneracy in a model-independent way through the Sunyaev-Zeldovich effect

We propose a model-independent \textit{Bézier parametric interpolation} to alleviate the degeneracy between baryonic and dark matter abundances by means of intermediate-redshift da…

We constrain the deceleration-acceleration epoch, namely the transition redshift , adopting model-independent techniques that utilize a calibrated -…
Intermediate redshift calibration of Gamma-ray Bursts and cosmic constraints in non-flat cosmology
Orlando Luongo, Marco Muccino
We propose how to calibrate long gamma-ray burst (GRB) correlations employing intermediate redshift data sets, instead of limiting to catalogs. To do so, we examine the…
On Larger Values in the CMB Dipole Direction
Orlando Luongo, Marco Muccino, Eoin Ó Colgáin +2
On the assumption that quasars (QSO) and gamma-ray bursts (GRB) represent \textit{standardisable candles}, we provide evidence that the Hubble constant adopts larger values i…
Do gamma-ray burst measurements provide a useful test of cosmological models?
Narayan Khadka, Orlando Luongo, Marco Muccino +1
We study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements -- that probe a largely unexplored part of cosmological redshift () space --…
Testing generalized logotropic models with cosmic growth
Kuantay Boshkayev, Talgar Konysbayev, Orlando Luongo +2
We check the dynamical and observational features of four typologies of logotropic dark energy models, leading to a \emph{thermodynamic cosmic speed up} fueled by a single fluid th…
