Meet the AAS Keynote Speakers: Daniel Scolnic
“The past, present, and future of the Hubble tension”: We interviewed cosmologist Daniel Scolnic for his plenary talk at the upcoming #AAS242!
Multi-messenger constraints on the Hubble constant
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!
UR: A Crisis in Cosmology? A new perspective on the Hubble Constant Tension
In our latest #UndergradResearch post, Sahil Ugale investigates the rate of expansion of the universe, and specifically the Hubble Constant Tension.
Early Dark Energy to the Rescue
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?
I’m Not Late, You’re Just Early: measuring the Hubble constant using time-delay cosmography
How can we use gravitational lensing to measure the expansion rate of the Universe?
