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…
