Primordial black hole in Lorentz-violating theories: Insights from Bumblebee gravity
Mohsen Khodadi, Javad T. Firouzjaee
The Bumblebee gravity (BG) model, featuring spontaneous Lorentz symmetry breaking via a vector field non-minimally coupled to curvature, has been widely used to explore Lorentz-vio…
Illuminating the dark universe in the multi-messenger era
Philippe Brax, Anne-Christine Davis, Md Riajul Haque +8
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a…
Confronting dark energy in Harada's Conformal Killing Gravity with observational data
Mohsen Khodadi, Gaetano Lambiase, Javad. T. Firouzjaee
Based on a comprehensive analysis of recent observational data-a combination of DESI DR1, Planck CMB, and Pantheon+ SN Ia-this study critically evaluates the two dark energy (DE) p…
Primordial observables of explicit diffeomorphism violation in gravity
Mohsen Khodadi, Nils A. Nilsson, Gaetano Lambiase +1
We investigate the potential for current and future gravitational-wave detectors to observe imprints of explicit diffeomorphism violation in primordial signals. Starting from a sim…
Could regular primordial black holes be dark matter?
Mohsen Khodadi
The recent proposal proposed by Paul Davies and colleagues [Phys. Rev. D \textbf{111} (2025) no.10, 103512] that regular primordial black holes (RPBHs) form stable, zero-temperatur…
A note on the stability of the Cauchy horizon in regular black holes without mass inflation
Mohsen Khodadi, Javad T. Firouzjaee
Unlike generic models of regular black holes (BHs) with nonzero surface gravity on both Cauchy and event horizons, an inner-degenerate counterpart with zero Cauchy horizon surface…
Event Horizon Telescope observations exclude compact objects in baseline mimetic gravity
Mohsen Khodadi, Sunny Vagnozzi, Javad T. Firouzjaee
Mimetic gravity has gained significant appeal in cosmological contexts, but static spherically symmetric space-times within the baseline theory are highly non-trivial: the two natu…
Hubble tension as a guide for refining the early Universe: Cosmologies with explicit local Lorentz and diffeomorphism violation
Mohsen Khodadi, Marco Schreck
This paper is dedicated to assessing modified cosmological settings based on the gravitational Standard-Model Extension (SME). Our analysis rests upon the Hubble tension (HT), whic…
A Survey of Strong Cosmic Censorship Conjecture Beyond Einstein's Gravity
Mohsen Khodadi, Javad T. Firouzjaee
The strong cosmic censorship conjecture (SCCC) proposed by Penrose states that the presence of the inner Cauchy horizon () in the black hole solutions does not threat…
