Charting Galactic Accelerations: When and How to Extract a Unique Potential from the Distribution Function
J. An, A. Naik, N. W. Evans +1
The advent of datasets of stars in the Milky Way with six-dimensional phase-space information makes it possible to construct empirically the distribution function (DF). Here, we sh…
Stellar Streams in Chameleon Gravity
A. P. Naik, N. W. Evans, E. Puchwein +2
Theories of gravity that incorporate new scalar degrees of freedom typically require screening mechanisms to ensure consistency with Solar System tests. One widely-studied mechanis…
Constraints on Chameleon f(R)-Gravity from Galaxy Rotation Curves of the SPARC Sample
Aneesh P. Naik, Ewald Puchwein, Anne-Christine Davis +2
In chameleon -gravity, the fifth force will lead to `upturns' in galaxy rotation curves near the screening radius. The location of the upturn depends on the cosmic background…
Imprints of Chameleon f(R) Gravity on Galaxy Rotation Curves
Aneesh P. Naik, Ewald Puchwein, Anne-Christine Davis +1
Current constraints on gravity are relatively weak on galactic and intergalactic scales. Screened modified gravity models can exhibit complex behaviour there without violating stri…
