Smoking Gun in Understanding Dark Matter

Dark Matter

Experts hope that a new study of how dark matter moves through galaxies can ultimately lead to an understanding of the mysterious substance.

"This study could be the" smoking gun "that takes us a step closer to understanding what dark matter is," Co-author Matthew Walker, a Carnegie Mellon University professor, said in a press release. "Our finding that it can be heated up and moved around helps motivate searches for a dark matter particle."

Dwarf galaxies

In the new paper, published in the magazine Monthly notices from the Royal Astronomical SocietySurvivors and colleagues at the University of Surrey and Ehh Zurich reported data on the distribution of dark matter – a mysterious and seemingly invisible substance believed to be the overwhelming majority of the world's population – in 16 dwarf galaxies.

"We found a truly remarkable relationship between the amount of dark matter in the centers of the tiny dwarfs, and the amount of star formation they have experienced over their lives," said co-author Justin Read from the University of California. Surrey. "The dark matter in the centers of the star-forming dwarfs appears to have been & # 39; heated up & # 39; and pushed it out."

Although it sounds esoteric, the report's authors say it is an exciting new clue that could lead to a better understanding of dark matter. Future models that explain the mysterious substance they say you need to be accounted for as the new star formation pushes it to the edges of galaxies, narrowing down the field for new theories.

It may even lead to new techniques, walker said, scientists could use to identify a dark matter particle – a spirit grille of experimental physics.
