Chasing a Starlight: Investigating One of the Oldest Known Galaxies with MUSE
Today’s authors study one of the oldest known galaxies and its spectra to learn more about the early universe.
Black holes – Do they grow stupendously large?
Black holes come in many different sizes. But is there a mass limit? The authors of today’s paper investigate the possibility of black holes a trillion times as massive as the sun. Surprisingly, they could also help explain the mysterious dark matter!
H0w Low Can EDE Go? Limiting Early Dark Energy with Large-scale Structure
Early dark energy has seen a lot of attention as a solution to the Hubble tension. Today’s paper rains on its parade!
Move over neural networks! – A new method for cosmological inference
Should neural networks give up trying to model cosmology and stick to sorting cat photos? Find out in todays post!
Is the Hubble Tension actually a Temperature Tension?
The Hubble tension is one of the biggest issues in modern cosmology. Why can we not agree on the expansion rate of the Universe? Today’s authors propose a solution: The actual disagreement might be in the assumed mean temperature of the cosmic microwave background.
