Resolving the explosion of supernova 2023ixf in Messier 101 within its complex circumstellar environment
E. A. Zimmerman, I. Irani, P. Chen +54
Observing a supernova explosion shortly after it occurs can reveal important information about the physics of stellar explosions and the nature of the progenitor stars of supernova…
Ground-based and JWST Observations of SN 2022pul: I. Unusual Signatures of Carbon, Oxygen, and Circumstellar Interaction in a Peculiar Type Ia Supernova
Matthew R. Siebert, Lindsey A. Kwok, Joel Johansson +79
Nebular-phase observations of peculiar Type Ia supernovae (SNe Ia) provide important constraints on progenitor scenarios and explosion dynamics for both these rare SNe and the more…
Ground-based and JWST Observations of SN 2022pul: II. Evidence from Nebular Spectroscopy for a Violent Merger in a Peculiar Type-Ia Supernova
Lindsey A. Kwok, Matthew R. Siebert, Joel Johansson +78
We present an analysis of ground-based and JWST observations of SN~2022pul, a peculiar "03fg-like" (or "super-Chandrasekhar") Type Ia supernova (SN Ia), in the nebular phase at 338…
SN 2022joj: A Peculiar Type Ia Supernova Possibly Driven by an Asymmetric Helium-shell Double Detonation
Chang Liu, Adam A. Miller, Samuel J. Boos +28
We present observations of SN 2022joj, a peculiar Type Ia supernova (SN Ia) discovered by the Zwicky Transient Facility (ZTF). SN 2022joj exhibits an unusually red $g_\mathrm{ZTF}-…
A Precursor Plateau and Pre-Maximum [O II] Emission in the Superluminous SN2019szu: A Pulsational Pair-Instability Candidate
Aysha Aamer, Matt Nicholl, Anders Jerkstrand +29
We present a detailed study on SN2019szu, a Type I superluminous supernova at , that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF forced p…
Early-time spectroscopic modelling of the transitional Type Ia Supernova 2021rhu with TARDIS
Luke Harvey, Kate Maguire, Mark R. Magee +15
An open question in SN Ia research is where the boundary lies between 'normal' Type Ia supernovae (SNe Ia) that are used in cosmological measurements and those that sit off the Phi…
Photometric study of the late-time near-infrared plateau in Type Ia supernovae
M. Deckers, O. Graur, K. Maguire +23
We present an in-depth study of the late-time near-infrared plateau in Type Ia supernovae (SNe Ia), which occurs between 70-500 d. We double the existing sample of SNe Ia observed…
A Systematic Study of Ia-CSM Supernovae from the ZTF Bright Transient Survey
Yashvi Sharma, Jesper Sollerman, Christoffer Fremling +35
Among the supernovae (SNe) that show strong interaction with the circumstellar medium, there is a rare subclass of Type Ia supernovae, SNe Ia-CSM, that show strong narrow hydrogen…
