A search for the variation of speed of light using galaxy cluster gas mass fraction measurements

In this paper, we implement a new method to test the invariance of the speed of light ( c ) as a function of redshift, by combining the measurements of galaxy cluster gas mass fraction, H ( z ) from cosmic chronometers, and Type-Ia supernovae (SNe Ia). In our analyses, we consider both a constant de...
