Novel Probes Project: Tests of gravity on astrophysical scales

Abstract

Modern instruments and observational programs in astrophysics and cosmology have opened new perspectives for probing general relativity on previously unexplored scales. This review provides both a methodological and an observational survey of the constraints on modified-gravity models using astrophysical objects in the cosmological, weak-field regime. It is embedded in the framework of the novel probes project, a forum connecting observers and theorists involved in the study of astrophysical tests of dark sector interactions.
