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…
Fragility of stealth solutions in mimetic gravity
Alireza Allahyari, Clarisse Donio, Mohammad Ali Gorji +2
We study a broad class of constrained mimetic-type extensions of general relativity with action , where i…
When Dark Energy Turns On: Constraints on a Critical Emergence Model
Mahdi Najafi, Mahdi Habibollahi, Masoume Reyhani +4
We investigate a specific emergent dark energy scenario, known as critically emergent dark energy (CEDE), in which dark energy is effectively absent in the early Universe and becom…
A Multi-Probe ISW Study of Dark Energy Models with Negative Energy Density: Galaxy Correlations, Lensing Bispectrum, and Planck ISW-Lensing Likelihood
Payam Ghafari, Mahdi Najafi, Mina Ghodsi Yengejeh +3
We investigate the late-time imprints of three dark energy (DE) models, namely, the Chevallier-Polarski-Linder (CPL) parametrization, CDM, and an Omnipotent DE model, on…
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…
Cosmological Inflation in Gravity
Maryam Shiravand, Saeed Fakhry, Javad T. Firouzjaee +1
Cosmological inflation remains a key paradigm for explaining the earliest stages of the Universe, yet the theoretical limitations of General Relativity (GR) motivate the developmen…
