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.
The annual meeting of the Astronomical Society of Australia happened last week; here’s a short summary of some of the incredible science happening Down Under!
A hypervelocity white dwarf might be left over from a Type Ia supernova. Today’s paper studies the white dwarf in detail.
Astronomers study a gravitationally lensed emission line galaxy, with implications for the characteristics of early galaxy populations.
The new high-resolution, hydra-headed PEPSI spectrograph is now in operation. One of the first targets it investigated is an ancient, planet-hosting star.
After accidentally observing the wrong star this paper’s authors discovered a previously-unknown solar twin, a type of star which can help shed light on a number of questions in astronomy.
