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.
Astrophysical Classics: The Lost Art of Fishing in a Black Hole
In a strange, half-lost, piece of work Roger Penrose draws four figures dropping their lines into the depths of a black hole, and in doing so finds a new and hugely influential way to steal energy away from the heart of a spinning singularity.
What’s your Cosmology? Ask CMB Maps.
Today’s paper takes you back to the time when anisotropies in the Cosmic Microwave Background first shaped Observational Cosmology into the field it is today.
