Yoga for dark matter: Making the Cold Dark Matter model more flexible
… and therefore more powerful. Describing dark matter as a fluid allows us to model dark matter candidates with great accuracy.
Testing micro with macro – from quantum to the cosmos
Quantum mechanics describes the unimaginably small, whilst Cosmology explains the unfathomably big. How the Universe blew up from one to the other is a question we think we’ve understood with the theory of inflation. But just how good is our picture of quantum mechanics? Today’s authors show that we can now use cosmological results to test our quantum framework.
Astrobites at AAS 232: Welcome
This week, Astrobites is attending the American Astronomical Society (AAS) meeting in Denver, Colorado! We’ll be bringing you highlights from the meeting all week long.
Did stripped stars re-ionize the Universe?
We still lack a good understanding of the source of ionizing photons in the early Universe. Can envelope-stripping from a binary companion help stars to re-ionize the early universe?
First Detection of the 21cm Cosmic Dawn Signal
Radio astronomers detect the first signature of a global 21cm signal with some interesting implications for dark matter.
A long time ago in a quasar far, far away…
The most distant quasar yet discovered illuminates the early universe…
