Dark Matter on the MoveScientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies. The findings provide the first observational evidence for the effect known as ‘dark matter heating,’ and give new clues as to what makes up dark matter. The research is published today in the journal Monthly Notices of the Royal Astronomical Society.

The Gaia Sausage: The Collision That Changed the Milky WayBetween 8 billion and 10 billion years ago, a dwarf galaxy crashed into our own Milky Way. The dwarf did not survive, but its final act redefined the shape of the Milky Way. Our galaxy has never been the same.

Scientists Spot Explosive Counterpart of LIGO/Virgo’s Latest Gravitational WavesToday, a team of scientists using the Dark Energy Camera (DECam), the primary observing tool of the Dark Energy Survey, was among the first to observe the fiery aftermath of a recently detected burst of gravitational waves, recording images of the first confirmed explosion from two colliding neutron stars ever seen by astronomers. Their data was bolstered by data captured at other observatories around the world.

Assembly Bias In Galaxy ClusteringRachel Mandelbaum, has shown that the relationship between galaxy clusters and their surrounding dark matter halo is more complex than previously thought. The researchers’ findings, published in Physical Review Letters, are the first to use observational data to show that, in addition to mass, a galaxy cluster’s formation history plays a role in how it interacts with its environment.
