Shortening the Baseline: Characterising Type Ia Supernovae Using
Joel M. Velasco, Paolo A. Mazzali, Christopher Ashall +8
An explorative study of Type Ia Supernovae (SNe Ia) light curves is presented. decline-rate metrics are used to evaluate alternative characterisations of light curve di…
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…
The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves
M. Kopsacheili, L. Galbany, G. Folatelli +32
We present observations of the 1991bg-like type Ia supernova (SN) 2023vjh, associated with the elliptical galaxy MCG+04-10-013. Its light-curve shape parameters ($Δm_{15}(B)=1.89 \…
JWST Medium-Resolution Infrared Spectroscopy of SN 2022acko: Tracing Molecule Formation in the Nebular Phase
K. Medler, T. Mera, C. Ashall +28
The Type II supernova (SN II) SN 2022acko was the first to be spectroscopically observed by the James Webb Space Telescope (). Here, we analyze SN 2022acko's second…
The local ultraviolet signature of Type Ia supernova environments from HST and MUSE
Lluís Galbany, Cullen Abelson, Alaa Alburai +17
The local environment of a Type Ia supernova (SN~Ia) traces the local stellar-population age (a statistical proxy for the progenitor age), star formation, dust, and chemical enrich…
JWST Observations of SN 2024ggi II: NIRSpec Spectroscopy and CO Modeling at 285 and 385 Days Past the Explosion
T. Mera, C. Ashall, P. Hoeflich +20
We present James Webb Space Telescope (JWST) NIRSpec observations of SN~2024ggi, spanning wavelengths of 1.7--5.5 micron at +285.51 and +385.27 days post-explosion. These nebular s…
