Early panchromatic spectra reveal helium in the thermonuclear supernova 2024kce

Abigail Polin, Dillon Hasenour, Sahana Kumar +26

Faint Type I supernovae blur the boundaries between spectroscopic classes, obscuring their progenitors and explosion mechanisms. One proposed origin is a double detonation, in whic…

Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny

Willem B. Hoogendam, David O. Jones, Christopher J. Storfer +26

We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at . We use integral-field Keck-II/…

Aarmed with Data: Bumps, Outflows, and Disk-like Emission in TDE 2025aarm

Aysha Aamer, Kate D. Alexander, Charlotte R. Angus +43

The origin of the optical emission in tidal disruption events (TDEs) remains one of the major outstanding questions in the field, in part due to the limited number of nearby events…

Decadal pre-explosion activity and circumstellar interaction in a supernova

Ting-Wan Chen, Amar Aryan, Sheng Yang +52

When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…

AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera

Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25

As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
