Clearing up the Redshifts of Obscured AGNs

Clearing up the Redshifts of Obscured AGNs

The redshifts of active galactic nuclei (AGNs) can help us piece together the universe’s evolutionary timeline. Unfortunately, measuring these redshifts can be pretty tricky. In today’s astrobite, we look at a trick for estimating and constraining the redshifts of AGNs that are – ironically enough – partially obscured from our view.

Testing micro with macro – from quantum to the cosmos

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.
