Probing Theories of Gravity with Phase Space-Inferred Potentials of Galaxy Clusters
Alejo Stark, Christopher J. Miller, Nicholas Kern +5
Modified theories of gravity provide us with a unique opportunity to generate innovative tests of gravity. In Chameleon f(R) gravity, the gravitational potential differs from the w…
