Strong Near-Infrared Carbon Absorption in the Transitional Type Ia SN 2015bp
S. D. Wyatt, D. J. Sand, E. Y. Hsiao +20
Unburned carbon is potentially a powerful probe of Type Ia supernova (SN) explosion mechanisms. We present comprehensive optical and near-infrared (NIR) data on the "transitional"…
SuperRAENN: A Semi-supervised Supernova Photometric Classification Pipeline Trained on Pan-STARRS1 Medium Deep Survey Supernovae
V. Ashley Villar, Griffin Hosseinzadeh, Edo Berger +18
Automated classification of supernovae (SNe) based on optical photometric light curve information is essential in the upcoming era of wide-field time domain surveys, such as the Le…
Photometric Classification of 2315 Pan-STARRS1 Supernovae with Superphot
Griffin Hosseinzadeh, Frederick Dauphin, V. Ashley Villar +17
The classification of supernovae (SNe) and its impact on our understanding of the explosion physics and progenitors have traditionally been based on the presence or absence of cert…
SN 2013aa and SN 2017cbv: Two Sibling Type Ia Supernovae in the spiral galaxy NGC 5643
Christopher R Burns, Chris Ashall, Carlos Contreras +26
We present photometric and spectroscopic observations of SN 2013aa and SN 2017cbv, two nearly identical type Ia supernovae (SNe Ia) in the host galaxy NGC 5643. The optical photome…
