Luminous Type II Short-Plateau SN 2023ufx: Asymmetric Explosion of a Partially-Stripped Massive Progenitor
Aravind P. Ravi, Stefano Valenti, Yize Dong +34
We present supernova (SN) 2023ufx, a unique Type IIP SN with the shortest known plateau duration ( 47 days), a luminous V-band peak ( = 18.42 0…
Asymmetries and Circumstellar Interaction in the Type II SN 2024bch
Jennifer E. Andrews, Manisha Shrestha, K. Azalee Bostroem +29
We present a comprehensive multi-epoch photometric and spectroscopic study of SN 2024bch, a nearby (19.9 Mpc) Type II supernova (SN) with prominent early high ionization emission l…
Spectropolarimetry of SN 2023ixf reveals both circumstellar material and helium core to be aspherical
Manisha Shrestha, Sabrina DeSoto, David J. Sand +33
We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc.…
Extended Shock Breakout and Early Circumstellar Interaction in SN 2024ggi
Manisha Shrestha, K. Azalee Bostroem, David J. Sand +40
We present high-cadence photometric and spectroscopic observations of supernova (SN) 2024ggi, a Type II SN with flash spectroscopy features which exploded in the nearby galaxy NGC…
SN2023fyq: A Type Ibn Supernova With Long-standing Precursor Activity Due to Binary Interaction
Yize Dong, Daichi Tsuna, Stefano Valenti +29
We present photometric and spectroscopic observations of SN 2023fyq, a type Ibn supernova in the nearby galaxy NGC 4388 (D18~Mpc). In addition, we trace long-standing precu…
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…
Circumstellar interaction signatures in the low luminosity type II SN 2021gmj
Nicolas Meza-Retamal, Yize Dong, K. Azalee Bostroem +25
We present comprehensive optical observations of SN~2021gmj, a Type II supernova (SN~II) discovered within a day of explosion by the Distance Less Than 40~Mpc (DLT40) survey. Follo…
