Galaxy morphology rules out astrophysically relevant Hu-Sawicki f (R) gravity
f ( R ) is a paradigmatic modified gravity theory that typifies extensions to General Relativity with new light degrees of freedom and hence screened fifth forces between masses. These forces produce observable signatures in galaxy morphology, caused by a violation of the weak equivalence principl...
