Observing the Universe’s Teenage Angst with Dropout Galaxies and CMB Lensing
In today’s bite, we explore a new method for studying how structure grows during the Universe’s formative teenage years, using rebellious dropout galaxies and peer-pressured CMB photons.
Cosmic Fishbones: Strange Radio Streaks Behind a Racing Pulsar
As a pulsar speeds through the interstellar medium, it leaves behind a long, radio-emitting tail shaped by ram pressure. In the Lighthouse Nebula, however, the X-ray emission and radio streaks show unexpected orientations, offering clues to how cosmic rays escape and trace surrounding magnetic fields.
There’s a great wave rippling through our galaxy
The dynamics of our galaxy become evermore complicated as today’s authors discover a mysterious wave propagating out towards its outskirts.
The Goldilocks Core: Habitability from the Inside Out
Not just the right temperature for water, but the right chemical recipe: only planets formed in a narrow nitrogen-, phosphorus-, and oxygen-balanced “Goldilocks” zone may keep life’s key ingredients available at their surface.
What happens when you poke a black hole?
Can a sneezing ant destroy a black hole? Regge and Wheeler set out to find out.
Hang On To Your Water, Super-Earths!
We use bottles, and sometimes a Brita, but how do planets store their water? The authors of today’s paper made a model to find out, and to evaluate whether certain planets are good at hanging on to their water or not.
