Anew study has found that the halo of the Milky Way is far more complex than previously realised, being made up of parts that are moving in opposite directions to each other. Daniela Carollo of the Australian National Un...
If these black holes existed in the Milky Way dark matter halo, they would cause long-timescale gravitational microlensing events lasting years13. The previous experiments were not sufficiently sensitive to such events14,15,16,17. Here we present the results of the search for long-timescale ...

The Milky Way isn’t alone in having a halo. Every galaxy has one dominated by dark matter. While we don’t see dark matter, it provides a framework for the distribution of ordinary, visible matter. That includes stars, clusters, and nebulae in the body of the galaxy, plus stars in th...
The halo of the Milky Way provides a laboratory to study the properties of the shocked hot gas that is predicted by models of galaxy formation. There is observational evidence of energy injection into the halo from past activity in the nucleus of the Milky Way1,2,3,4; however, the origin...

BEIJING, July 2 (Xinhua) -- Chinese scientists recently proposed that the current dark matter halo of the Milky Way is "slightly oblate." The study, conducted by researchers from the University of the Chinese Academy of Sciences (UCAS), in collaboration with several domestic and international re...
Astronomers believe that the baryon (stellar) halo of the Milky Way retains a fossil imprint of how it was formed. But a vast literature shows that the struggle to interpret the observations within a consistent framework continues. The evidence indicates that the halo has built up through a pro...
