The Radial Acceleration Relation in Rotationally Supported Galaxies, Stacy McGaugh, Federico Lelli and Jim Schombert, Accepted for Publication in Physical Review Letters (19 September 2016)
We report a correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons. The same relation is followed by 2693 points in 153 galaxies with very different morphologies, masses, sizes, and gas fractions. The correlation persists even when dark matter dominates. Consequently, the dark matter contribution is fully specified by that of the baryons. The observed scatter is small and largely dominated by observational uncertainties. This radial acceleration relation is tantamount to a natural law for rotating galaxies.
No MACHOs or WIMPs and SUSY etc. lost into the black hole.
Mimicking dark matter in Horndeski gravity, Massimiliano Rinaldi (12 August 2016)
Since the rediscovery of Horndeski gravity, a lot of work has been devoted to the exploration of its properties, especially in the context of dark energy. However, one sector of this theory, namely the one containing the coupling of the Einstein tensor to the kinetic term of the scalar field, shows some surprising features in the construction of black holes and neutron stars. Motivated by these new results, I explore the possibility that this sector of Horndeski gravity can mimic cold dark matter at cosmological level and also explain the flattening of galactic rotation curves. I will show that it is possible to achieve both goals with a minimal set of assumptions.
If it mimics or simulates dark matter, then it IS dark matter.

Gauge Fields, Nonlinear Realizations, Supersymmetry, E.A. Ivanov, Physics of Particles and Nuclei (4 September 2016), DOI:10.1134/S1063779616040080
This is a brief survey of the all-years research activity in the Sector “Supersymmetry” (the former Markov Group) at the Bogoliubov Laboratory of Theoretical Physics. The focus is on the issues related to gauge fields, spontaneously broken symmetries in the nonlinear realizations approach, and diverse aspects of supersymmetry.

So if it’s not supersymmetry, then what is it?

Ok, so I’m gonna need a new axion. A super axion!
Coupled to gravitons and ordinary matter through the Higgs.
This is my special theory of gravity modification.

Now I just need a theory.
ITS gonna be weird.
Trust me on that.
