Active Galactic Nuclei are some of the brightest objects in the Universe. But what is responsible for switching on these supermassive engines?
Today’s paper works to catch a leak with a new technique, using resolved Lyman-alpha line profiles to gain insight into the epoch of reionization
An accidental discovery of two new galaxies, hiding behind clouds of dust in the furthest reaches of the Universe.
How does the radiation that caused reionization travel out of galaxies? Studying a strongly-lensed system called the Sunburst Arc could tell us more.
Traces of magnified dust offer a requiem to early, dead galaxies that ran out of gas
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
