Join us on Thursday, April 17th for another installment of our Spring Physics Colloquia series! Guest lecturer, Dr. Tanvi Karwal, will be visiting from Kavli Institute for Cosmological Physics at the University of Chicago.

 

Abstract:

Different methods of determining the current rate of expansion of the Universe disagree at high significance. This 'Hubble tension' has persisted despite intense scrutiny and may hint at new physics beyond the standard model of cosmology. I have extensively investigated this anomaly, and my talk will present the discrepant measurements and draw phenomenological insight into solving this tension with new physics. I applied these insights, introducing a new 'early dark energy' component to the Universe that resolves the Hubble tension. Despite the successes of this model, challenges remain - including improving the original model for EDE and constraining it more robustly. My talk will present my work in addressing these challenges, with applications beyond cosmic tensions.
