Colloquium
Overlooked Dark Matter signatures
Abstract
The discovery of dark matter (DM) followed cosmic gravitational observation (Zwicky, 1933), which remains inconsistent within known physics. Solar system observables exhibit unexpected planetary dependencies, even though no remote force beyond gravity exists. The question arises whether persisting local mysterious / anomalous/ … observations are signals from the dark sector. Gravitational focusing of DM streams should result to short focal ranges since the impact goes with 1/(speed)2. Also, the inner mass distribution of solar system bodies can perform as gravitational lenses for streaming DM with flux amplification up to ~109 x, compared to few % for isotropic DM. The analysis of a number of observations from near outer space fits in our streaming DM scenario.
Using measurements of cosmic positrons, the same analysis points to DM with the positrons being secondaries of parent DM. New direct measurements of cosmic rays can validate the first result. The telescopes in Tenerife might have relevant data worth re-analyzing them. An exciting Endeavor!
