How accurate are transient spectral classification tools? -- A study using 4,646 SEDMachine spectra

Young-Lo Kim, Isobel Hook, Andrew Milligan +13

Accurate classification of transients obtained from spectroscopic data are important to understand their nature and discover new classes of astronomical objects. For supernovae (SN…

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…

Searching for late-time interaction signatures in Type Ia supernovae from the Zwicky Transient Facility

Jacco H. Terwel, Kate Maguire, Georgios Dimitriadis +23

The nature of the progenitor systems and explosion mechanisms that give rise to Type Ia supernovae (SNe Ia) are still debated. The interaction signature of circumstellar material (…
