Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…
Multi-Epoch Spectropolarimetry for a Sample of Type IIn Supernovae: Persistent Asymmetry in Dusty Circumstellar Material
Christopher Bilinski, Nathan Smith, G. Grant Williams +5
We present multi-epoch spectropolarimetry and spectra for a sample of 14 Type IIn supernovae (SNe IIn). We find that after correcting for likely interstellar polarization, SNe IIn…
A High-Velocity Scatterer Revealed in the Thinning Ejecta of a Type II Supernova
Douglas C. Leonard, Luc Dessart, D. John Hillier +7
We present deep, nebular-phase spectropolarimetry of the Type II-P/L SN 2013ej, obtained 167 days after explosion with the European Southern Observatory's Very Large Telescope. The…
The electron-capture origin of supernova 2018zd
Daichi Hiramatsu, D. Andrew Howell, Schuyler D. Van Dyk +27
In the transitional mass range ( 8-10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture superno…
Discovery and Rapid Follow-up Observations of the Unusual Type II SN 2018ivc in NGC 1068
K. A. Bostroem, S. Valenti, D. J. Sand +44
We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual Type II supernova that exploded in NGC 1068 (D=10.1 Mpc). The light curve of SN 2018ivc d…
Searches After Gravitational-waves Using ARizona Observatories (SAGUARO): System Overview and First Results from Advanced LIGO/Virgo's Third Observing Run
M. J. Lundquist, K. Paterson, W. Fong +53
We present Searches After Gravitational-waves Using ARizona Observatories (SAGUARO), a comprehensive effort dedicated to the discovery and characterization of optical counterparts…
