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…

ASASSN-15hy: an under-luminous, red 03fg-like type Ia supernova

J. Lu, C. Ashall, E. Y. Hsiao +33

We present photometric and spectroscopic observations of the 03fg-like type Ia supernova (SN Ia) ASASSN-15hy from the ultraviolet (UV) to the near-infrared (NIR). ASASSN-15hy share…

SN 2013ai: a link between hydrogen-rich and hydrogen-poor core-collapse supernovae

S. Davis, P. J. Pessi, M. Fraser +33

We present a study of optical and near-infrared (NIR) spectra along with the light curves of SN 2013ai. These data range from discovery until 380 days after explosion. SN 2013ai is…

Supernova 2018cuf: A Type IIP supernova with a slow fall from plateau

Yize Dong, S. Valenti, K. A. Bostroem +34

We present multi-band photometry and spectroscopy of SN 2018cuf, a Type IIP ("P" for plateau) supernova (SN) discovered by the Distance Less Than 40 Mpc survey (DLT40) within 24 ho…

Optical and Near-Infrared Observations of the Nearby Type Ia Supernova 2017cbv

Lingzhi Wang, Carlos Contreras, Maokai Hu +28

Supernova (SN) 2017cbv in NGC 5643 is one of a handful of type Ia supernovae (SNe~Ia) reported to have excess blue emission at early times. This paper presents extensive $BVRIYJHK_…

Carnegie Supernova Project II: The slowest rising Type Ia supernova LSQ14fmg and clues to the origin of super-Chandrasekhar/03fg-like events

E. Y. Hsiao, P. Hoeflich, C. Ashall +34

The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties which may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum i…
