Supernovae Unite: Combining Pantheon+ and DES-SN5YR

Ryan Camilleri, Jaemyoung Lee, Tamara Davis +21

We present the Hubble diagram and cosmological constraints resulting from the combination of the Pantheon+ and DES-SN5YR supernova (SN) samples, which we refer to as Unite. Unite u…

Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters

Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93

The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…

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…

The Dark Energy Bedrock All-Sky Supernova Program: Cross Calibration, Simulations, and Cosmology Forecasts

Maria Acevedo, Nora F. Sherman, Dillon Brout +12

Type Ia supernovae (SNe Ia) have been essential for probing the nature of dark energy; however, most SN analyses rely on the same low-redshift sample, which may lead to shared syst…

Amalgame: Cosmological Constraints from the First Combined Photometric Supernova Sample

Brodie Popovic, Daniel Scolnic, Maria Vincenzi +11

Future constraints of cosmological parameters from Type Ia supernovae (SNe Ia) will depend on the use of photometric samples, those samples without spectroscopic measurements of th…
