The Hubble Tension is Still Tense
Today’s authors make a high-precision measurement to address a key issue in modern cosmology: the Hubble tension. Read on to see what they found!
Guide to ΛCDM
In this Guide, we breakdown one of the most important models in astrophysics: the ΛCDM model of cosmology!
Over the Limit: Accretion and Feedback of Early Black Holes
Merry Christmas! In today’s bite, learn how simulations of black hole accretion and feedback are informing our understanding of the evolution of the earliest black holes.
Correlating galaxies with the temperature of Cosmic Microwave Background photons to probe cosmology
Today’s bite will discuss how we can combine the fluctuations in the temperature of the oldest photons in the Universe with the presence of galaxies in the sky to measure motions.
Zig-zagging across the universe
What’s better than a single gravitational lens? A double gravitational lens! Learn about how light from a distant quasar zig-zags across the universe because of the first double gravitational lens to be observed!
Did AGNs drive the Cosmic Reionization?
Guest author Teja Teppala shows us how supermassive black holes may be energizing the early Universe!
