Tracking Down the Quasar Light Switch
We’re still not sure what causes quasars, some of the brightest objects in the universe, to switch on. Today’s authors present a compelling case for galaxy mergers being the culprit!
X-raying Quasar Titans in the Distant Universe
Journey to the distant universe with today’s paper, as we discover what the X-ray emission from high-redshift quasars can tell us about their formation and accretion physics!
Far, Farther, Quasars – One Step Closer to the Early Formation of Supermassive Objects
The existence of distant quasars requires the formation of supermassive stars in the very early universe. But is it possible to form supermassive stars so early? Find out in today’s bite!
A Galactic Prison Break: Tracing Lyα Escape at High Redshift
Astrophysics is a lot like life in that sometimes the journey matters more than the destination. In today’s paper, which looks at the Hydrogen Lyman-α spectral line in a high-redshift protocluster, that’s absolutely the case!
Pulling Back the Curtain on the Formation of the First Supermassive Black Holes
How do supermassive black holes get to be so supermassive? Today’s authors explore how we might be able to answer that question with the SKA pulsar timing array!
A Missing Link Between High-Redshift Galaxies and Quasars
Where do quasars come from? Today’s authors report a new observation that helps shed light on this mystery!
