Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Is the evolution of galaxies and their AGN driven by past mergers?
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
The most distant quasar yet discovered illuminates the early universe…
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.
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.
