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…

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…

Follow-up of SN 2025wny III: Spectroscopic Time-delay Measurements of a Strongly Gravitationally Lensed Superluminous Supernova

Joel Johansson, Edvard Mörtsell, Ariel Goobar +30

We present spatially resolved spectra and infer the time-delays between the multiple images of the strongly gravitationally lensed superluminous supernova (SLSN) 2025wny at z=2.015…

The host galaxies of 2003fg-like type Ia supernovae

Lluís Galbany, Chris Ashall, Jing Lu +19

SN~2003fg-like events are a peculiar type Ia supernova (SN~Ia) subtype characterized by broader light curves, higher near-infrared luminosities, and stronger carbon absorptions at…

ZTF SN Ia DR2 follow-up: early excess in Type Ia supernova light curves

Tomás E. Müller-Bravo, Kate Maguire, Alaa Alburai +15

There is broad consensus that Type Ia supernovae (SNe Ia) are the thermonuclear explosions of C/O white dwarfs (WDs) in binary systems, but their progenitors and explosion mechanis…

Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey

DES Collaboration, T. M. C. Abbott, M. Adamow +166

We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…
