Rubin ToO 2024: Envisioning the Vera C. Rubin Observatory LSST Target of Opportunity program

Igor Andreoni, Raffaella Margutti, John Banovetz +86

The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall of 2025. The LSST survey cadence has been designed via a community-driven pr…

The Hubble Constant from Blue Type Ia Supernovae

Christa Gall, Luca Izzo, Radoslaw Wojtak +1

There is a persistent tension of about between the value of the Hubble constant, as derived from the local distance ladder vs. the cosmic microwave background, signaling ei…

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…

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…

Origin of the strong sodium absorption of the lensed supernova 2016geu at z=0.4

Christa Gall, Jens Hjorth, Lise Christensen +7

The origin of strong sodium absorption, which has been observed for a few nearby Type Ia supernovae (SNe Ia), remains elusive. Here we analyse two high-signal-to-noise, intermediat…

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…
