The Hubble Crisis and how it might be resolved by Aaron Glanville

Cosmology is at a crossroads – two independent measurements of Hubble’s constant, the rate of expansion within our universe, are in disagreement. Measurements made using nearby “standard candles” (such as supernovae) provide a much lower rate of expansion than measurements made using cosmological `”standard rulers” (such as the large scale structure of the universe). In this talk, Aaron discuss some of the possible solutions proposed to bridge the gap between these two measurements. In particular, he focus on one of the simplest possible explanations – what if simple observational error caused our standard ruler to be out of alignment?

Aaron Glanville completed his first degree in astrophysics at the University of Queensland in 2019. He is currently undertaking a PhD at UQ, focusing on the analysis of large scale structure in the universe, and the physical description of expanding space.  His research interests include exploring the effects of redshift errors on cosmological constraints, BAO cosmology, and the general relativistic description of expanding space.

There is no cost for this event and visitors are welcome to attend.
