Lightcurve Modelling of 2,205 ZTF DR2 Type~Ia Supernovae: Implications for SN Ia Physics and Cosmology

Nikhil Sarin, Ellen Lindsjö, Lisa Kelsey +11

We fit the multi-band light curves of 2,205 Type Ia supernovae (SNe~Ia) from the Zwicky Transient Facility DR2 with a one-zone radioactive decay model with a phenomenological addit…

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…

Rates and properties of type Ia supernovae in galaxy clusters within the Dark Energy Survey

M. Toy, P. Wiseman, M. Sullivan +59

We identify 66 photometrically classified type Ia supernovae (SNe Ia) from the Dark Energy Survey (DES) that have occurred within red-sequence selected galaxy clusters. We compare…

Core-collapse Supernovae in the Dark Energy Survey: Luminosity Functions and Host Galaxy Demographics

M. Grayling, C. P. Gutiérrez, M. Sullivan +73

We present the luminosity functions and host galaxy properties of the Dark Energy Survey (DES) core-collapse supernova (CCSN) sample, consisting of 69 Type II and 50 Type Ibc spect…

Understanding the extreme luminosity of DES14X2fna

M. Grayling, C. P. Gutiérrez, M. Sullivan +66

We present DES14X2fna, a high-luminosity, fast-declining type IIb supernova (SN IIb) at redshift , detected by the Dark Energy Survey (DES). DES14X2fna is an unusual memb…

The Mystery of Photometric Twins DES17X1boj and DES16E2bjy

M. Pursiainen, C. Gutierrez, P. Wiseman +80

We present an analysis of DES17X1boj and DES16E2bjy, two peculiar transients discovered by the Dark Energy Survey (DES). They exhibit nearly identical double-peaked light curves wh…
