Constraints on Rastall gravity from current observational data

Mahnaz Asghari, Hooman Moradpour

We study the cosmological features of Rastall gravity, where the covariant energy-momentum conservation is modified to $\nabla_{μ} T_{ν}^{μ} = λ \nabla_{ν} R$ in curved spacetime. For this purp…

Modified $f (R, T)$ theory in light of gravitational wave standard sirens

Mahnaz Asghari, Ahmad Sheykhi

In this paper, we ponder observational constraints on the modified $f (R, T)$ gravity, where the gravitational action is a function of Ricci scalar $R$ plus the trace of the energy-m…

Growth of cosmic perturbations in the modified $f (R, T)$ gravity

Mahnaz Asghari, Ahmad Sheykhi

We explore the generalized $f (R, T)$ modified theory of gravity, where the gravitational Lagrangian is a function of Ricci scalar $R$ and the trace of the energy-momentum tensor $T$ …

Gravitational wave probes of Barrow cosmology with LISA standard sirens

Mahnaz Asghari, Alireza Allahyari, David F. Mota

We study the Barrow cosmological model, which proposes that quantum gravity effects create a complex, fractal structure for the universe's apparent horizon. We leverage the thermod…
