Supernovae Unite: Host-Galaxy Mass Measurements of Type Ia Supernovae and Their Impact on Cosmology
J. Lee, R. Camilleri, T. M. Davis +22
Current consensus suggests that Type Ia supernova (SN Ia) brightnesses post light-curve standardization correlate with their host-galaxy stellar masses, which must be accounted for…
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…
Dark sirens and the impact of redshift precision
Madeline L. Cross-Parkin, Cullan Howlett, Tamara M. Davis +1
With the growing number of gravitational wave detections, achieving a competitive measurement of with dark sirens is becoming increasingly feasible. The expansion of the Ligo…
Improving the Determination of Supernova Cosmological Redshifts by Using Galaxy Groups
Erik R. Peterson, Bastien Carreres, Anthony Carr +9
At the low-redshift end () of the Hubble diagram with Type Ia Supernovae (SNe Ia), the contribution to Hubble residual scatter from peculiar velocities is of similar size t…
First Cosmology Results Using Type Ia Supernovae From the Dark Energy Survey: Survey Overview and Supernova Spectroscopy
C. B. D'Andrea, M. Smith, M. Sullivan +108
We present spectroscopy from the first three seasons of the Dark Energy Survey Supernova Program (DES-SN). We describe the supernova spectroscopic program in full: strategy, observ…
Steve: A hierarchical Bayesian model for Supernova Cosmology
S. R. Hinton, T. M. Davis, A. G. Kim +66
We present a new Bayesian hierarchical model (BHM) named Steve for performing type Ia supernova (SNIa) cosmology fits. This advances previous works by including an improved treatme…
