Astrobites for your ears. Three grad students bring you cutting-edge research findings in astronomy and connect the dots between diverse subfields.
Shoot, someone made the mistake of letting Cole pick the episode topic. In this episode, Cole, Cormac, and Shashank talk about the big boy on cosmology campus: Lambda CDM. This model has gotten a bit too big for its britches we think: what are the things about the universe that this model can’t explain? Shashank gives us a tour through the dark matter hearts of galaxies which don’t match up with cosmological predictions and Cormac shows us how 1500 (ish? We’re not clear on this one.) supernovae could hint at a fundamental flaw in Lambda CDM.
