Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse

Morgan MacLeod, Sarah Blunt, Robert J. De Rosa +10

We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion t…

JWST Validates HST Distance Measurements: Selection of Supernova Subsample Explains Differences in JWST Estimates of Local H0

Adam G. Riess, Dan Scolnic, Gagandeep S. Anand +16

JWST provides new opportunities to cross-check the HST Cepheid/SNeIa distance ladder, which yields the most precise local measure of H0. We analyze early JWST subsamples (~1/4 of t…

Reconnaissance with JWST of the J-region Asymptotic Giant Branch in Distance Ladder Galaxies: From Irregular Luminosity Functions to Approximation of the Hubble Constant

Siyang Li, Adam G. Riess, Stefano Casertano +5

We study stars in the J-regions of the asymptotic giant branch (JAGB) of near-infrared color magnitude diagrams in the maser host NGC 4258 and 4 hosts of 6 Type Ia supernovae (SN I…

The Mira Distance to M101 and a 4% Measurement of H0

Caroline D. Huang, Wenlong Yuan, Adam G. Riess +8

The giant spiral galaxy M101 is host to the nearest recent Type Ia Supernova (SN 2011fe) and thus has been extensively monitored in the near-infrared to study the late-time lightcu…

The Mira Distance Ladder

Caroline D. Huang

Here we provide a review of Mira variables, their basic properties, and Period-Luminosity Relations with an emphasis on their role in measuring the Hubble Constant. The usage of mu…
