Active Galactic Nuclei have a history of causing trouble
Many astronomers believe that AGN activity is responsible for suppressing star formation. However, it appears that maybe the past behaviour of AGN is what’s really to blame.
How to jump start a supermassive black hole
Active Galactic Nuclei are some of the brightest objects in the Universe. But what is responsible for switching on these supermassive engines?
Dust off your old galaxies, we’ve got a new discovery!
An accidental discovery of two new galaxies, hiding behind clouds of dust in the furthest reaches of the Universe.
A story of light and darkness
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
Red, dead (and flat?) galaxies in distant clusters
Most galaxies are either star-forming disks, or red, dead spheroids. But, have galaxy clusters now shown that this divide isn’t quite so clear?
