Einstein’s theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby strong gravitational lens ESO 325-G004 provides a laboratory to probe the weak-field regime of gravity and measure the spatial curvature generated per unit mass, γ. By reconstructing the observed light profile of the lensed arcs and the observed spatially resolved stellar kinematics with a single self-consistent model, we conclude that γ = 0.97 ± 0.09 at 68% confidence. Our result is consistent with the prediction of 1 from General Relativity and provides a strong extragalactic constraint on the weak-field metric of gravity.

A new model for the structure of gallobicchulite, Ca8(Ga2SiO6)4(OH)8, has been derived from a combined refinement of EXAFS and neutron powder diffraction data. The structure is based on a pseudo-cubic ordered unit cell, related to that of tugtupite, with long-range disorder owing to domains in three orientations parallel to the cubic faces.
