Studying gravity on cosmological scales is HARD. Today’s papers build a framework to extend the standard cosmology toolbox, which means we can keep more of our data and learn more about gravity in the process.
The satellites of galaxy Centaurus A seem to be in an unusual arrangement, which also has some fascinating cosmological implications!
Conferences have had to change a lot due to Covid-19, how can we design effective online spaces for collaboration? I sat down with the organisers of Cosmology from Home to find out!
Today’s paper proposes a possible origin of LIGO/VIRGO black holes that takes us back to the earliest moments of the universe!
The oldest objects in the universe weigh in on the heated debate over the “Hubble Tension,” disagreements on the expansion rate of the universe.
One of the most important issues in cosmology is the Hubble tension – why do different probes not agree on how fast the Universe is expanding? A popular solution is changing the physics in the very early Universe. Today’s paper explores, why this approach might not work, by measuring the expansion rate with observables independent of the early Universe.
