Let’s Dust off the Hubble Constant
Could the Hubble Tension finally be solved with a little spring cleaning? It’s more likely than you think.
Insight from the Oldest Objects in 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.
Solving the Hubble tension might require more than changing the early 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.
UR: Measuring the Hubble Constant With Dynamical Tides In Inspiraling Neutron Star Binaries
In this #UndergradResearch post, James Sunseri explores the possibility of using gravitational waves from colliding neutron stars to measure the Hubble Constant without observing the electromagnetic spectrum.
Bursting the Hubble Trouble Bubble: Measuring H0 with Fast Radio Bursts
Do you like fast radio bursts but hate the Hubble tension? If so, then this paper showing the first measurement of the Hubble constant using FRB observations is for you!
H0 tension: South Pole-arization edition with SPT-3G
Today’s paper takes us on a journey to the South Pole for the latest episode in the H0 tension mystery. Can ΛCDM model extensions finally crack the case?
