Comparison of $f (R, T)$ Gravity with Multiple Datasets

Vincent R. Siggia, Eric D. Carlson

We examine $f (R, T) = R + I^» T^{I^} µ$ gravity models by finding the best fit parameters for various values of $I^µ$ . This is accomplished by analyzing data from the cosmic microwave backgrou…

Exploration of Parameters in f(R,T) Gravity and Comparison with Type Ia Supernovae Data

Vincent R. Siggia, Eric D. Carlson, P. Lee Pryor

The expansion of the Universe in $f (R, T)$ gravity is studied. We consider functions of the form $f (R, T) = R + I^» T^{I^} µ$ where $I^µ < 1$ . We find that for all models with $I^µ < 0$ , the Univers…

Comparison of $f (R, T)$ Gravity with Type Ia Supernovae Data

Vincent R. Siggia, Eric D. Carlson

The expansion of the universe in $f (R, T)$ gravity is studied. By focusing on functions of the form $f (R, T) = f_{1} (R) + f_{2} (T)$ , we assert that present day acceleration can be achieved i…
