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 in curved spacetime. For this purp…
Modified theory in light of gravitational wave standard sirens
Mahnaz Asghari, Ahmad Sheykhi
In this paper, we ponder observational constraints on the modified gravity, where the gravitational action is a function of Ricci scalar plus the trace of the energy-m…
Growth of cosmic perturbations in the modified gravity
Mahnaz Asghari, Ahmad Sheykhi
We explore the generalized modified theory of gravity, where the gravitational Lagrangian is a function of Ricci scalar and the trace of the energy-momentum tensor …
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…
On observational signatures of multi-fractional theory
Mahnaz Asghari, Ahmad Sheykhi
We study the multi-fractional theory with -derivatives, where the multi-fractional measure is considered to be in the time direction. The evolution of power spectra and also the…
Observational constraints on the fractal cosmology
Mahnaz Asghari, Ahmad Sheykhi
In this paper, we explore a fractal model of the universe proposed by Calcagni [JHEP{\bf03}(2010)120] for a power-counting renormalizable field theory living in a fractal spacetime…
Observational constraints of the modified cosmology through Barrow entropy
Mahnaz Asghari, Ahmad Sheykhi
Taking into account a fractal structure for the black hole horizon, Barrow argued that the area law of entropy is modified due to quantum-gravitational effects (Barrow in Phys Lett…
Observational constraints on Tsallis modified gravity
Mahnaz Asghari, Ahmad Sheykhi
The thermodynamics-gravity conjecture reveals that one can derive the gravitational field equations by using the first law of thermodynamics and vice versa. Considering the entropy…
Perturbation level interacting dark energy model and its consequence on late-time cosmological parameters
Mahnaz Asghari, Shahram Khosravi, Amir Mollazadeh
In the present paper, we study the capability of interacting dark energy model with pure momentum transfer in the dark sector to reconcile tensions between low redshift observation…
On structure formation from a small-scales-interacting dark sector
Mahnaz Asghari, Jose Beltran Jimenez, Shahram Khosravi +1
We consider a cosmological model with an interaction between dark matter and dark energy which leaves the background cosmology unaffected and only affects the evolution of the pert…
