Deur's latest paper is an update of his previous work, that confirms his prediction based upon the self-interaction of gravitational fields, that the ellipticity of a galaxy and its apparent dark matter content are correlated.
Of course, that's notable mostly because it makes it possible to distinguish Deur's approach from other hypotheses. As the body text of the paper explains, this approach explains far more without purporting to deviate at all from General Relativity without a cosmological constant:
In [Deur's] framework, a homogeneous system locally dense enough so that the nonlinearity of General Relativity is not negligible, should display a correlation between its dynamical total mass analyzed using Newton’s gravity and its spacial asymmetry (e.g., the galaxy ellipticity). Besides the present correlation, this framework also explains the correlation between dynamical and baryonic matter accelerations observed, the Cosmic Microwave Background anisotropies, matter power spectrum, large structure formation, and unifies the origins of dark matter and dark energy.
The new paper and its abstract are as follows:
We investigate a correlation between the dark matter content of elliptical galaxies and their ellipticity that was initially reported in 2014. We use new determinations of dark matter and ellipticities that are posterior to that time. Our data set consists of 237 elliptical galaxies passing a strict set of criteria. We find a relation between the mass-to-light ratio and ellipticity, e, that is well fit by M/L = (14.1 ± 5.4)e, which agrees with the result reported in 2014.
