SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova
D. Farias, C. Gall, G. Narayan +29
We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…
Blast: a Web Application for Characterizing the Host Galaxies of Astrophysical Transients
D. O. Jones, P. McGill, T. A. Manning +14
Characterizing the host galaxies of astrophysical transients is important to many areas of astrophysics, including constraining the progenitor systems of core-collapse supernovae,…
Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models
C. R. Angus, S. E. Woosley, R. J. Foley +35
We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…
The Gravity Collective: A Comprehensive Analysis of the Electromagnetic Search for the Binary Neutron Star Merger GW190425
D. A. Coulter, C. D. Kilpatrick, D. O. Jones +34
We present an ultraviolet-to-infrared search for the electromagnetic (EM) counterpart to GW190425, the second-ever binary neutron star (BNS) merger discovered by the LIGO-Virgo-KAG…
SN 2024ggi in NGC 3621: Rising Ionization in a Nearby, CSM-Interacting Type II Supernova
W. V. Jacobson-Galán, K. W. Davis, C. D. Kilpatrick +28
We present UV/optical/NIR observations and modeling of supernova (SN) 2024ggi, a type II supernova (SN II) located in NGC 3621 at 7.2 Mpc. Early-time ("flash") spectroscopy of SN 2…
Anomaly Detection and Approximate Similarity Searches of Transients in Real-time Data Streams
P. D. Aleo, A. W. Engel, G. Narayan +29
We present LAISS (Lightcurve Anomaly Identification and Similarity Search), an automated pipeline to detect anomalous astrophysical transients in real-time data streams. We deploy…
Final Moments II: Observational Properties and Physical Modeling of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early-time ( days) spectra show transient, narrow emission lines…
