Astrobites at AAS 232: Day 3 and Day 4
We report on Day 3 of the summer AAS meeting in Denver, CO. Highlights include a look at the triumphs of helioseismology, discussions on merging galaxies, and a new way to weigh the Milky Way.
Stellar Streams & The Nature of Dark Matter
Will future telescopes reveal the nature of dark matter imprinted in the stellar streams stretched around our galaxy?
Capturing neutrons in the thin disk
Elements heavier than iron are forged by neutron-capture processes. How are they distributed in the Galaxy?
No escape from the Milky Way
Over its lifetime, the Milky Way has battled with several dwarf galaxies and won, leaving behind the streams of stars we observe today. This bite explores whether such a battle resulted in the formation of the mighty Monoceros ring!
How fast is dark matter?
Can observations of stars help to determine the local dark matter velocity?
All-sky spectroscopy with SDSS-V
A spectrum is worth a thousand pictures. But all-sky spectra? Well, I bet they are worth many many thousands of pictures — introducing SDSS-V.
