Quasi-periodic oscillations in rotating and deformed spacetimes
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +2
Quasi-periodic oscillation (QPOs) analysis is important for understanding the dynamical behavior of many astrophysical objects during transient events such as gamma-ray bursts, sol…
Equivalence principle violation in nonminimally coupled gravity and constraints from Lunar Laser Ranging
Riccardo March, Orfeu Bertolami, Marco Muccino +1
We analyze the dynamics of the Sun-Earth-Moon system in the context of a particular class of theories of gravity where curvature and matter are nonminimally coupled (NMC). These th…
Breaking the baryon-dark matter degeneracy in a model-independent way through the Sunyaev-Zeldovich effect
Anna Chiara Alfano, Orlando Luongo, Marco Muccino
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…
Unifying the dark sector through a single matter fluid with non-zero pressure
Peter K. S. Dunsby, Orlando Luongo, Marco Muccino
We explore a generalised unified dark energy model that incorporates a non-minimal interaction between a tachyonic fluid and an additional scalar field. Specifically, we require th…
Luminosity of accretion disks around rotating regular black holes
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4
We consider thin accretion disks in the field of a class of rotating regular black holes. For this purpose, we obtain the radius of the innermost stable circular orbit, …
Accretion disk in the Hartle-Thorne spacetime
Yergali Kurmanov, Marco Muccino, Kuantay Boshkayev +4
We consider the circular motion of test particles in the gravitational field of a rotating deformed object described by the Hartle-Thorne metric. This metric represents an approxim…
Quasi-periodic oscillations for spherically symmetric regular black holes
Kuantay Boshkayev, Anuar Idrissov, Orlando Luongo +1
We consider the recent data sets of quasi-periodic oscillations from eight different low mass X-ray binaries. We here interpret their physical features in the context of given regu…
