A New Window for Testing the PPN in the Strong-Field Regime: Stellar Rotation of S301
Mohsen Khodadi, Salvatore Capozziello
The recently discovered S301 star, with an orbital period of 8.7 years and eccentricity , reaches a pericenter of just --- approximately nine times…
Constraining the Tilted Dipole Cosmology with Primordial Nucleosynthesis and Baryogenesis
Mohsen Khodadi
The tilted dipole cosmology extends the standard model by incorporating a preferred spatial direction and separate bulk velocities for matter and radiation, offering a potential ex…
Primordial gravitational waves from spontaneous Lorentz symmetry breaking
Mohsen Khodadi, Gaetano Lambiase, Leonardo Mastrototaro +1
We study the effect of Spontaneous Lorentz Symmetry Breaking (SLSB) on Primordial Gravitational Waves (PGWs) generated during inflation. The SLSB is induced by a time-like Bumblebe…
Harvesting energy driven by Comisso-Asenjo process from Kerr-MOG black holes
Mohsen Khodadi, David F. Mota, Ahmad Sheykhi
Magnetic reconnection is a process that plays a critical role in plasma astrophysics by converting magnetic energy into plasma particle energy. Recently, Comisso and Asenjo demonst…
Evolution of Spherical Overdensities in Energy-Momentum-Squared Gravity
Bita Farsi, Ahmad Sheykhi, Mohsen Khodadi
Employing the spherical collapse (SC) formalism, we investigate the linear evolution of the matter over-density for energy-momentum-squared gravity (EMSG), which in practical pheno…
Spontaneous Lorentz symmetry breaking effects on GRBs jets arising from neutrino pair annihilation process near a black hole
Mohsen Khodadi, Gaetano Lambiase, Leonardo Mastrototaro
The study of neutrino pair annihilation into electron-positron pairs () is astrophysically well-motivated because it is a possible powering mechanism for the g…
Superradiant energy extraction from rotating hairy Horndeski black holes
Sohan Kumar Jha, Mohsen Khodadi, Anisur Rahaman +1
Adopting the manifest of low-frequency and low mass for the scalar perturbation, we perform a semi-classical analysis of the superradiance phenomenon for a rotating hairy Horndeski…
Constraining the Lorentz-Violating Bumblebee Vector Field with Big Bang Nucleosynthesis and Gravitational Baryogenesis
Mohsen Khodadi, Gaetano Lambiase, Ahmad Sheykhi
By keeping the cosmological principle i.e., an isotropic and homogeneous universe, we consider the cosmology of a vector-tensor theory of gravitation known as the \textit{bumblebee…
Probing the Lorentz Symmetry Violation Using the First Image of Sagittarius A*: Constraints on Standard-Model Extension Coefficients
Mohsen Khodadi, Gaetano Lambiase
Thanks to unparalleled near-horizon images of the shadows of Messier 87* (M87*) and Sagittarius A* (Sgr A*) delivered by the Event Horizon Telescope (EHT), two amazing windows open…
Emergent Universe from Energy-Momentum Squared Gravity
Mohsen Khodadi, Alireza Allahyari, Salvatore Capozziello
In order to bypass the big bang singularity, we develop an emergent universe scenario within a covariant extension of General Relativity known as \emph{"Energy-Momentum Squared Gra…
Magnetic Reconnection and Energy Extraction from a Spinning Black Hole with Broken Lorentz Symmetry
Mohsen Khodadi
In the Penrose process and the Blandford-Znajek mechanism, the rotational energy of a black hole (BH) is extracted via particle fission and magnetic tension, respectively. Recently…
Strongly Magnetized Hot QCD Matter and Stochastic Gravitational Wave Background
Mohsen Khodadi, Ujjal Kumar Dey, Gaetano Lambiase
The first-order phase transitions in the early Universe are one of the well-known sources which release the stochastic background of gravitational waves. In this paper, we study th…
No-Hair Theorem in the Wake of Event Horizon Telescope
Mohsen Khodadi, Gaetano Lambiase, David F. Mota
Thanks to the release of the extraordinary EHT image of shadow attributed to the M87* supermassive black hole (SMBH), we have a novel window to assess the validity of fundamental p…
The quark chemical potential of QCD phase transition and the stochastic background of gravitational waves
Salvatore Capozziello, Mohsen Khodadi, Gaetano Lambiase
The detection of stochastic background of gravitational waves (GWs), produced by cosmological phase transitions (PTs), is of fundamental importance because allows to probe the phys…

Mohsen Khodadi, Kourosh Nozari, Habib Abedi +1
We reconsider the stochastic gravitational wave background spectrum produced during the first order hadronization process, in presence of ultraviolet cutoffs suggested by the gener…
