However, it has been historically difficult to pin down the dark matter contribution to the total mass density in the Milky Way, particularly in the innermost regions of the Galaxy and in the solar neighbourhood. Here we present an up-to-date compilation of Milky Way rotation curve measurements...
and dark matter has the influence to shape a galaxy by keeping it "corralled" as it moves through space. Our own Milky Way has a dark matter halo that does this. In addition, dark matter keeps galaxy clusters together
Dr. Kafle was able to measure the mass of the dark matter in the Milky Way by studying the speed of stars throughout the galaxy, including the edges, which had never been studied to this detail before. He used a powerful technique developed by British astronomer James Jeans in 1915-decades...
dark matter in the Milky Way has showed there is half as much of the mysterious substance(神秘物质)as previously thought.Australian astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800 billion times the mass of the Sun...
This book begins by reveiwing the evidence for dark matter, particularly in our own Galaxy where measurements are most accurate. The candidates for various types of dark matter are investigated as well as the ongoing attempts to detect them. Those alternative theories to dark matter for solving ...

It appears that dark matter — the mysterious stuff that makes up most of the matter in the universe — may be able to interact with other bits of dark matter, and not just through the pull of gravity.
“Our work shows satellite galaxies of the Milky Way may provide important tests of different dark matter theories,” said Sales, an assistant professor of physics and astronomy and an astrophysicist with expertise in numerical simulations of galaxy formation. “We show the interplay between dark ma...
