Looking for a dark matter needle in an X-ray stack
Can an unexplained signal found inside multiple galaxy clusters tell us something about dark matter? Find out about a tantalising indirect detection by X-ray astronomers.
Where Did All the Dark Matter Go?
The discovery of a second dark matter deficient galaxy by van Dokkum et al. has caused the debate on galaxies lacking dark matter to resurface.
Satellites of satellites should exist. Let’s go look for them.
Today’s paper makes predictions for the yet-to-be-observed dwarf galaxy population around Andromeda’s satellite galaxy, M33. It provides scientific justification for a future mission with WFIRST.
Astrobites at AAS 233: Day 4
We report on Day 4 of the winter AAS meeting in Seattle, WA. Highlights include an exploding space cow, a discussion of data in astronomy, the latest look at the possibility of life beyond earth, and an exploration of climate impact much closer to home.
Meet the AAS Keynote Speakers: Dr. Elena Aprile
What’s next in the future of dark matter direct detection experiments? Find out in Dr. Elena Aprile’s plenary talk at #AAS233!
Seeing Double: Binary stars in dwarf galaxies
Two (stars) aren’t always better than one, especially when you’re trying to track down dark matter in tiny galaxies.
