[APCTP Colloquium] Is Our Standard Model of Cosmology Incorrect | Prof. Wendy Freedman

Date: 06 December, 2024 Speaker: Prof. Wendy Freedman Over the last decade, there has been mounting evidence for what has become known as the ‘Hubble tension’. Local measurements of the current expansion rate of the universe (a quantity known as the Hubble constant) are at odds with that inferred from measurements of the cosmic microwave background. I will describe new results from a major James Webb Space Telescope (JWST) program to improve measurements of the Hubble constant. Relative to the Hubble Space Telescope, JWST has 10 times greater sensitivity and 4 times higher resolution in the near-infrared, and is providing a powerful new means of addressing challenges in previous measurements.
