JWST NIRSpec+MIRI Observations of the nearby Type IIP supernova 2022acko

M. Shahbandeh, C. Ashall, P. Hoeflich +65

We present JWST spectral and photometric observations of the Type IIP supernova (SN) 2022acko at ~50 days past explosion. These data are the first JWST spectral observations of a c…

Carnegie Supernova Project-I and -II: Measurements of using Cepheid, TRGB, and SBF Distance Calibration to Type Ia Supernovae

Syed A. Uddin, Christopher R. Burns, Mark M. Phillips +44

We present an analysis of Type Ia Supernovae (SNe~Ia) from both the Carnegie Supernova Project~I (CSP-I) and II (CSP-II), and extend the Hubble diagram from the optical to the near…

Carnegie Supernova Project-II: Near-infrared spectral diversity and template of Type Ia Supernovae

Jing Lu, Eric Y. Hsiao, Mark M. Phillips +30

We present the largest and most homogeneous collection of near-infrared (NIR) spectra of Type Ia supernovae (SNe Ia): 339 spectra of 98 individual SNe obtained as part of the Carne…

Near-infrared and Optical Nebular-phase Spectra of Type Ia Supernovae SN 2013aa and SN 2017cbv in NGC 5643

Sahana Kumar, Eric Y. Hsiao, Chris Ashall +23

We present multi-wavelength time-series spectroscopy of SN 2013aa and SN 2017cbv, two Type Ia supernovae (SNe Ia) on the outskirts of the same host galaxy, NGC 5643. This work util…

Carnegie Supernova Project-II: Near-infrared Spectroscopy of Stripped-Envelope Core-Collapse Supernovae

M. Shahbandeh, E. Y. Hsiao, C. Ashall +29

We present 75 near-infrared (NIR; 0.82.5 m) spectra of 34 stripped-envelope core-collapse supernovae (SESNe) obtained by the Carnegie Supernova Project-II (CSP-II), encompass…

Measuring an off-Center Detonation through Infrared Line Profiles: The peculiar Type Ia Supernova SN~2020qxp/ASASSN-20jq

P. Hoeflich, C. Ashall, S. Bose +17

We present and analyze a near infrared(NIR) spectrum of the under-luminous Type Ia supernova SN~2020qxp/ASASSN-20jq obtained with NIRES at the Keck Observatory 191 days after B-ban…
