Subgiant in the spotlight: characterising a new benchmark star
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Are AGN Quiescent Adolescents?
Is the evolution of galaxies and their AGN driven by past mergers?
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.
