In modified gravity theories that seek to explain cosmic acceleration, dwarf galaxies in low density environments can be subject to enhanced forces. The class of scalar-tensor theories, which includes f(R) gravity, predict such a force enhancement (massive galaxies like the Milky Way can evade it through a screening mechanism that protects the interior of the galaxy from this ``fifth'' force). We study observable deviations from GR in the disks of late-type dwarf galaxies moving under gravity… Expand

Astrophysical tests of modified gravity: the morphology and kinematics of dwarf galaxies
This paper is the third in a series on tests of gravity using observations of stars and nearby dwarf galaxies. We carry out four distinct tests using published data on the kinematics and morphologyExpand
Astrophysical tests of modified gravity: Stellar and gaseous rotation curves in dwarf galaxies

Stellar Structure and Tests of Modified Gravity
Theories that attempt to explain cosmic acceleration by modifying gravity typically introduces a long-range scalar force that needs to be screened on small scales. One common screening mechanism isExpand

It is argued that the observational programme developed to test dark energy needs to be augmented to capture new tests of gravity on astrophysical scales, and identifies new regimes that cosmological surveys could target to test gravity. Expand
Cosmological Tests of Gravity
