Scalar modes of polarization and speed of gravitational waves in $f (R)$ gravity

Utkal Keshari Dash, Bal Krishna Yadav, Murli Manohar Verma

We explore the gravitational waves (GWs) within the framework of the $f (R)$ gravity model represented by $f (R) = R^{1 + δ} / R_{c}^{δ}$ in the weak field approximation. In this scenario, gra…

Extended galactic rotational velocity profiles in $f (R)$ gravity background

Vipin Kumar Sharma, Bal Krishna Yadav, Murli Manohar Verma

An attempt has been made to explore the galactic dynamics via the rotational velocity beyond the Einstein's geometric theory of gravity. It is inspired from the geometric relation…

Dark matter as scalaron in $f (R)$ gravity models

Bal Krishna Yadav, Murli Manohar Verma

We explore the scalar field obtained under the conformal transformation of the spacetime metric $g_{μν}$ from the Jordan frame to the Einstein frame in $f (R)$ gravity. This scalar…

Dynamics of $f (R)$ gravity models and asymmetry of time

Murli Manohar Verma, Bal Krishna Yadav

We solve the field equations of modified gravity for $f (R)$ model in metric formalism. Further, we obtain the fixed points of the dynamical system in phase space analysis of $f (R)$ …
