Testing the Strong Equivalence Principle: Detection of the External Field Effect in Rotationally Supported Galaxies
Kyu-Hyun Chae, Federico Lelli, Harry Desmond +3
The strong equivalence principle (SEP) distinguishes General Relativity from other viable theories of gravity. The SEP demands that the internal dynamics of a self-gravitating syst…
Galaxy morphology rules out astrophysically relevant Hu-Sawicki gravity
Harry Desmond, Pedro G. Ferreira
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. Th…
Spatially offset black holes in the Horizon-AGN simulation and comparison to observations
Deaglan J. Bartlett, Harry Desmond, Julien Devriendt +2
We study the displacements between the centres of galaxies and their supermassive black holes (BHs) in the cosmological hydrodynamical simulation Horizon-AGN, and in a variety of o…
Screened fifth forces lower the TRGB-calibrated Hubble constant too
Harry Desmond, Jeremy Sakstein
The local distance ladder measurement of the Hubble constant requires a connection between geometric distances at low redshift and Type Ia supernovae in the Hubble flow, which may…
