Looking for a dark matter needle in an X-ray stack
Can an unexplained signal found inside multiple galaxy clusters tell us something about dark matter? Find out about a tantalising indirect detection by X-ray astronomers.
Connecting galaxy properties to their star-formation histories
Star-forming galaxies form stars at different rates. Could this be the model that reveals the underlying physics?
How to Diagnose the Light from Early Galaxies
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
A long time ago in a quasar far, far away…
The most distant quasar yet discovered illuminates the early universe…
Hunting for new physics in a black hole’s shadow
Hints of a theory beyond General Relativity could lie in the shape of a black hole’s shadow. An Earth-sized telescope will allow us to resolve these shadows for the first time.
Exploding stars and sleight of hand: A case of magnetic misdirection
Supernova remnant magnetic fields may play a key role in accelerating electrons to relativistic velocities. West et al. investigate the magnetic field conditions inside young supernova remnants and discover that they may not be as well-behaved as they appear.
