Unifying all mass discrepancies with one effective gravity law?

Zhao, HongSheng, Famaey, Benoit

Understand

A remarkably tight relation is observed between the Newtonian gravity sourced by the baryons and the actual gravity in galaxies of all sizes.

  • This can be interpreted as the effect of a single effective force law depending on acceleration.
  • This is however not the case in larger systems with much deeper potential wells, such as galaxy clusters.
  • Here we explore the possibility of an effective force law reproducing mass discrepancies in all extragalactic systems when depending on both acceleration and the depth of the potential well.
