Breaking the AGB Color Degeneracy with Variability and HO: A Consistent Picture of AGB Chemistry, Dust, and the J-Region Across Environments

Caroline D. Huang, Massimo Marengo, Antonio Capodagli +7

Resolved asymptotic giant branch (AGB) populations present many observational puzzles. We consider three often treated separately: photometric C/O classification boundaries must be…

Old Universe, Young SNe Ia: A Statistical Analysis of Type Ia Supernova Progenitor Age from 6,983 TITAN Host Galaxies, and Implications for Cosmology

Yukei Murakami, Jack Tweddle, Phil Wiseman +17

Correlations between standardized Type Ia supernova (SN Ia) luminosities and host-galaxy properties are routinely modeled to avoid bias in cosmological parameter inference. A recen…

Forward-modelling Milky Way Cepheids: selection effects and physical priors in the Gaia-HST calibration

Richard Stiskalek, Adam Riess, Harry Desmond +2

The advent of high-precision Gaia parallaxes for Milky Way Cepheids enables per cent-level calibration of the local distance ladder and the Hubble constant . We revisit the Mi…

Still Accelerating: Type Ia supernova cosmology is robust to host galaxy age evolution

Phil Wiseman, Brodie Popovic, Mark Sullivan +14

Type Ia supernovae are a cornerstone of modern cosmology, providing first evidence for cosmic acceleration and new tests of dark energy. Son et al. 2025 (S25) claim a strong redshi…

TITAN DR1: An Improved, Validated, and Systematically-Controlled Recalibration of ATLAS Photometry toward Type Ia Supernova Cosmology

Elijah G. Marlin, Yukei S. Murakami, Dillon Brout +14

ATLAS (Asteroid Terrestrial Last Alert System) is a time-domain survey using four telescopes, covering the entire sky. It has observed over 10,000 spectroscopically confirmed Type…

Constraining Fifth Forces using the Local Distance Ladder: Implications for the Hubble Tension

Marcus Högås, Edvard Mörtsell, Harry Desmond +1

We revisit the local distance ladder measurement of the Hubble constant in models where gravity is modified by a fifth force, an additional long-range interaction. In many such the…
