What happens to a galaxy as it falls into a giant cluster? The Three Hundred simulations explore the fate of gas in these cosmic encounters.
We aren’t the only ones with gassy problems…why don’t sub-Saturns accrete enough gas to become full-blown Saturns or Jupiters?
The circumgalactic and intergalactic media may contain the majority of baryonic matter in the universe, but their low density makes them extremely faint. Can an instrument designed to image low surface brightness objects help shed light on these ghostly structures?
Radiation from massive stars can melt away protoplanetary disks. What can the leftover disks tell us about the environment from which they formed?
The first ever shadow of a black hole has been imaged using a global network of ground-based telescopes. A concept study of a space-based interferometric experiment shows that in the future, black holes could be imaged with even more precision.
A mysterious type of matter, quark-gluon plasma, may lie at the heart of neutron stars.
