Researchers propose a new, lighter form of dark matter that may account for a mystery in the Milky Way's Central Molecular Zone (CMZ), where charged hydrogen clouds perplex scientists. The study, published in Physical Review Letters, indicates that energy signatures from this region might originate from this new dark matter, challenging current models that rely on heavier candidates like WIMPs. This discovery could reshape our understanding of dark matter's role in cosmic structure formation.
At the center of our galaxy sit huge clouds of positively charged hydrogen, a mystery to scientists for decades because normally the gas is neutral.
The energy signatures radiating from this part of our galaxy suggest that there is a constant, roiling source of energy doing just that, and our data says it might come from a much lighter form of dark matter.
