Description
In this work we estimated the cosmological constant in a pioneering approach by using galactic superclusters in the layout of $f(R,T)$ gravity. We set $f(R,T) = R + 2\lambda T$ where $\lambda$ is the model parameter. We report that appropriate values of $\lambda$ generate cosmological constant ($\Lambda$) values in harmony with observational value of $1.1056\times10^{-52}m^{-2}$. We also delineate that for $\lambda = 0$ which corresponds to GR, yields physically unacceptable results.
