Spectroscopy of AT 2016blu's recurring supernova impostor outbursts
Mojgan Aghakhanloo, Nathan Smith, Jennifer E. Andrews +7
We present spectra of the supernova (SN) impostor AT 2016blu spanning over a decade. This transient exhibits quasiperiodic outbursts with a 113 d period, likely triggered by…
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…
JWST/MIRI Observations of Newly Formed Dust in the Cold, Dense Shell of the Type IIn SN 2005ip
Melissa Shahbandeh, Ori D. Fox, Tea Temim +42
Dust from core-collapse supernovae (CCSNe), specifically Type IIP SNe, has been suggested to be a significant source of the dust observed in high-redshift galaxies. CCSNe eject lar…
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.…
Circumstellar Interaction in the Ultraviolet Spectra of SN 2023ixf 14-66 Days After Explosion
K. Azalee Bostroem, David J. Sand, Luc Dessart +20
SN 2023ixf was discovered in M101 within a day of explosion and rapidly classified as a Type II supernova with flash features. Here we present ultraviolet (UV) spectra obtained wit…
Three Quenched, Faint Dwarf Galaxies in the Direction of NGC 300: New Probes of Reionization and Internal Feedback
D. J. Sand, B. Mutlu-Pakdil, M. G. Jones +18
We report the discovery of three faint and ultra-faint dwarf galaxies -- Sculptor A, Sculptor B and Sculptor C -- in the direction of NGC 300 (D=2.0 Mpc), a Large Magellanic Cloud-…
One Year of SN 2023ixf: Breaking Through the Degenerate Parameter Space in Light-Curve Models with Pulsating Progenitors
Brian Hsu, Nathan Smith, Jared A. Goldberg +21
We present and analyze the extensive optical broadband photometry of the Type II SN 2023ixf up to one year after explosion. We find that, when compared to two pre-existing model gr…
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…
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…
