Type IIn Supernovae. I. Uniform Light-curve Characterization and a Bimodality in the Radiated Energy Distribution
Daichi Hiramatsu, Edo Berger, Sebastian Gomez +3
We present the largest uniform study to date of Type IIn supernovae (SNe IIn), focusing in this first paper on the multiband optical light curves of 490 SNe IIn. The sample, constr…
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…
AT2023vto: An Exceptionally Luminous Helium Tidal Disruption Event from a Massive Star
Harsh Kumar, Edo Berger, Daichi Hiramatsu +10
We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a b…
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…
The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description
Sebastian Gomez, Matt Nicholl, Edo Berger +25
We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…
Superphot+: Realtime Fitting and Classification of Supernova Light Curves
Kaylee M. de Soto, Ashley Villar, Edo Berger +9
Photometric classifications of supernova (SN) light curves have become necessary to utilize the full potential of large samples of observations obtained from wide-field photometric…
