UR: The Atomic Dark Matter Model: A Possible Solution to the Shortcomings of CDM
Could dark matter behave similarly to regular matter? If so, could dark matter halos collapse and form structures, like a black hole? In this work we explore the Atomic Dark Matter Model and predicting structure formation in it using simple algebra. We build on the current literature by showing that for certain values of the variables that govern dark matter interactions, we won’t be able to determine if the halo will be able to collapse using methods to track the dark matter number densities and how efficiently the halo can dispose of its initial energy.
A Family Adrift
(22) Kalliope and its large moon Linus were thought to be traveling through the solar system as a lone pair with no further asteroid family to accompany them. This seems strange, as Linus was most likely created by a giant impact which would have to leave other fragments. Today’s authors are convinced they found the family belonging to Kalliope and the reason it hasn’t been identified sooner.
Heist in Space: Chasing the Stolen Planets
Plenty of committed and planned heists give examples of how to steal diamonds and pearls. But how to steal a whole planet? Easy! You just need to be a star in a star forming region.
