The Early Light Curve of SN 2023bee: Constraining Type Ia Supernova Progenitors the Apian Way
Griffin Hosseinzadeh, David J. Sand, Sumit K. Sarbadhicary +39
We present very early photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2023bee, starting about 8 hr after the explosion, which reveal a strong excess in…
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…
Record-breaking polarization from the interacting superluminous supernova 2017hcc
Jon C. Mauerhan, Nathan Smith, G. Grant Williams +12
We present multiepoch spectropolarimetry of the superluminous interacting Type IIn supernova SN2017hcc, covering 16 to 391 days after explosion. In our first epoch we measure conti…
The Superluminous Type IIn Supernova ASASSN-15ua: Part of a continuum in extreme precursor mass loss
Danielle Dickinson, Nathan Smith, Jennifer E. Andrews +3
We present a series of ground-based photometry and spectroscopy of the superluminous Type IIn supernova (SN) ASASSN-15ua, which shows evidence for strong interaction with pre-exist…
Recurring outbursts of the supernova impostor AT 2016blu in NGC 4559
Mojgan Aghakhanloo, Nathan Smith, Peter Milne +8
We present the first photometric analysis of the supernova (SN) impostor AT 2016blu in NGC 4559. This transient was discovered by the Lick Observatory Supernova Search in 2012 and…
Repeating periodic eruptions of the supernova impostor SN 2000ch
Mojgan Aghakhanloo, Nathan Smith, Peter Milne +7
We analyse photometric observations of the supernova (SN) impostor SN 2000ch in NGC 3432 covering the time since its discovery. This source was previously observed to have four out…
