“The past, present, and future of the Hubble tension”: We interviewed cosmologist Daniel Scolnic for his plenary talk at the upcoming #AAS242!
The Hubble tension remains a major open question in contemporary cosmology. Today’s paper addresses using gravitational waves and light from neutron star mergers to constrain the Hubble constant.

Planning on using gravitational waves for cosmology or measuring distances? It’s dangerous out there — don’t forget this handy guide!
In our latest #UndergradResearch post, Sahil Ugale investigates the rate of expansion of the universe, and specifically the Hubble Constant Tension.
Tensions are rising with the beloved lambda-CDM model of the Universe. Is it time for Early Dark Energy to swoop in to save the day?
How can we use gravitational lensing to measure the expansion rate of the Universe?
