SN 2023tsz: A helium-interaction driven supernova in a very low-mass galaxy

B. Warwick, J. Lyman, M. Pursiainen +49

SN 2023tsz is a Type Ibn supernova (SNe Ibn) discovered in an extremely low-mass host. SNe Ibn are an uncommon subtype of stripped-envelope core-collapse SNe. They are characterise…

Reduction of the type Ia supernova host galaxy step in the outer regions of galaxies

M. Toy, P. Wiseman, M. Sullivan +63

Using 1533 type Ia supernovae (SNe Ia) from the five-year sample of the Dark Energy Survey (DES), we investigate the relationship between the projected galactocentric separation of…

Calibrating the Absolute Magnitude of Type Ia Supernovae in Nearby Galaxies using [OII] and Implications for

M. Dixon, J. Mould, C. Lidman +69

The present state of cosmology is facing a crisis where there is a fundamental disagreement in measurements of the Hubble constant (), with significant tension between the e…

Modelling the impact of host galaxy dust on type Ia supernova distance measurements

B. Popovic, P. Wiseman, M. Sullivan +65

Type Ia Supernovae (SNe Ia) are a critical tool in measuring the accelerating expansion of the universe. Recent efforts to improve these standard candles have focused on incorporat…

The Dark Energy Survey Supernova Program: Light curves and 5-Year data release

B. O. Sánchez, D. Brout, M. Vincenzi +82

We present photometric light curves for the full 5 years of the Dark Energy Survey Supernova program (DES-SN), obtained with both forced Point Spread Function (PSF) photomet…

The Dark Energy Survey Supernova Program: Cosmological Analysis and Systematic Uncertainties

M. Vincenzi, D. Brout, P. Armstrong +93

We present the full Hubble diagram of photometrically-classified Type Ia supernovae (SNe Ia) from the Dark Energy Survey supernova program (DES-SN). DES-SN discovered more than 20,…

The Dark Energy Survey: Cosmology Results With ~1500 New High-redshift Type Ia Supernovae Using The Full 5-year Dataset

DES Collaboration, T. M. C. Abbott, M. Acevedo +156

We present cosmological constraints from the sample of Type Ia supernovae (SN Ia) discovered during the full five years of the Dark Energy Survey (DES) Supernova Program. In contra…
