Kinetic bias: it reinforces the argument for the axionic origin of the dark matter

Argument for the axionic origin of the dark matter

A group of astrophysicists from the University of Michigan and the University of California at Berkeley investigate axion movements. They suggest a scenario called kinetic displacement. According to the scientists, it can strengthen the argument for the equivalence of the axion and the dark matter. The new concept introduces new possibilities for detecting the dark matter.

After all, its existence is still a mystery, although its presence is confirmed by several hypotheses. But a new study takes axion velocity as a basis, which can provide a key idea of mysterious matter.

All previous studies have been able to successfully suggest that the universe is replete with the dark matter. But some facts remain unexplored. The kinetic mechanism of displacement can be based on the axion field, which passes through all possible barriers and gradually begins to oscillate under the influence of friction.

The scientists created a zero velocity field of axions, and then the mechanism of kinetic displacement was discovered. It produces more axions than other traditional mechanisms. And it significantly changes the calculations of axion content in dark matter.

The scientists also concluded that such process allows the axionic dark matter to react more with ordinary matter, that exceeds the prediction of the conventional displacement mechanism. Astrophysicist Keisuke Harigaya believes that the axion field existed initially when the early Universe appeared, it could be static.

Based on such assumptions, the astrophysicists have found that in fact the axion field can be initially dynamic as a consequence of the theory of quantum gravity with the axions. A new kinetic displacement mechanism revealed a completely new axion. It has the potential for greater interaction strength and can be detected during planned experimental searches.
