Cosmological consequences of scale-dependent Barrow-Tsallis entropy
Giuseppe Gaetano Luciano, Orlando Luongo, Marco Muccino
The paper explores a cosmological model with a scale‑dependent Barrow‑Tsallis entropy, deriving modified Friedmann equations and confronting the model with various early‑ and late‑…
The macroscopic precession model of quasi-periodic oscillations for rotating compact objects
Orlando Luongo, Marco Muccino
The relativistic precession model (RPM) interprets the twin kilohertz quasi-periodic oscillations (QPOs) as geodesic frequencies of test particles orbiting in the spacetime of X-ra…
Testing dark matter density profiles based on Padé approximants of different orders
Talgar Konysbayev, Orlando Luongo, Marco Muccino +5
We investigate whether low-order Padé rational functions can be used as empirical density profiles for modeling dark matter halos from galaxy RCs. We introduce three parameterizat…
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…
The macroscopic precession model: describing quasi-periodic oscillations including internal structures of test bodies
Gabriele Bianchini, Orlando Luongo, Marco Muccino
The relativistic precession model (RPM) is widely-considered as a benchmark framework to interpret quasi-periodic oscillations (QPOs), albeit several observational inconsistencies…
