Numerical analysis of quasi-periodic oscillations with spherical spacetimes

Kuantay Boshkayev, Orlando Luongo, Marco Muccino

We numerically test quasi-periodic oscillations using three theoretically-motivated models of spacetime adopting neutron star sources. Then, we compare our findings with a spherica…

Numerical analyses of M31 dark matter profiles

Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4

We reproduce the rotation curve of the Andromeda galaxy (M31) by taking into account its bulge, disk, and halo components, considering the last one to contain the major part of dar…

Constraints on the transition redshift from the calibrated Gamma-ray Burst - correlation

Marco Muccino, Orlando Luongo, Deepak Jain

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…

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…
