Where are your parents? The authors of today’s paper investigate the origins of the Orphan Stream in our galaxy!
The Giant Bubble Driving Nearly All Nearby Star Formation
We’ve known for some time that we reside in the Local Bubble, a cavity of low-density gas excavated by an orchestra of dying stars ~15 Myrs ago. Today’s authors find that this Bubble’s expansion is driving nearly all nearby star formation.
Exploring the Invisible Milky Way
Today’s paper looks at our own galaxy to measure its dark matter halo mass.
Peering through the lens of the Milky Way Supermassive Black Hole
One of the most important observations by the next generation of giant telescopes will be made by pointing towards the Supermassive Black Hole at the center of our galaxy.
A Dark Matter Fossil Record: Using Geology to Probe Time-Varying Dark Matter Signals
Move over, dinosaurs — the search for fossilized dark matter is the new trend in (galactic) geology.
