Constraining a $f(R,L_m)$ Gravity Cosmological Model with Observational Data

G. K. Goswami, Anirudh Pradhan, Syamala Krishnannair

We investigate a spatially flat FLRW cosmological model in the framework of modified gravity described by the function \( f(R, L_m) = αR + L_m^β+ γ\), where \( L_m \) is the matter…
