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…
