Unifying baryogenesis with dark matter production
Orlando Luongo, Nicola Marcantognini, Marco Muccino
We here propose a mechanism that predicts, at early times, both baryon asymmetry and dark matter origin and that recovers the spontaneous baryogenesis during the reheating. Working…
Cassini and extra force constraints to nonminimally coupled gravity with screening mechanism
Riccardo March, Orfeu Bertolami, Marco Muccino +2
We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises…
A roadmap to gamma-ray bursts: new developments and applications to cosmology
Orlando Luongo, Marco Muccino
Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to . In this short review, we first discuss gamma-ray…
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 --…
The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs
R. Ruffini, R. Moradi, J. A. Rueda +14
We recall evidence that long gamma-ray bursts (GRBs) have binary progenitors and give new examples. Binary-driven hypernovae (BdHNe) consist of a carbon-oxygen core (CO$_{\rm core}…
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…
