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…
What Does the Virial Coefficient of the \Hb Broad-Line Region Depend On?
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +37
We combine our dynamical modeling black hole mass measurements from the Lick AGN Monitoring Project 2016 sample with measured cross-correlation time lags and line widths to recover…
The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +62
We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring…
The Lick AGN Monitoring Project 2016: Velocity-Resolved Hβ Lags in Luminous Seyfert Galaxies
Vivian U, Aaron J. Barth, H. Alexander Vogler +61
We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3-m Shane telescope at Lick Observatory from April 2016 to M…
Making Sense of Nothing
Douglas C. Leonard
A model of the optical light detected following the merger of two neutron stars reveals polarization to be a unique probe of the geometry of the kilonova explosion that accompanied…
