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.
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.
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?
Radio astronomers detect the first signature of a global 21cm signal with some interesting implications for dark matter.
The most distant quasar yet discovered illuminates the early universe…
How do we measure the mass of our own galaxy? Today’s authors use simulations to compare (and improve) several methods.
