JAGB 2.0: Improved Constraints on the J-region Asymptotic Giant Branch–based Hubble Constant from an Expanded Sample of JWST Observations
The J-region asymptotic giant branch (JAGB) is an overdensity of stars in the near-infrared, attributed to carbon-rich AGB stars, and recently used as a standard candle for measuring extragalactic distances and the Hubble constant. Using JWST in Cycle 2, we extend JAGB measurements to six hosts of n...
