      Maund, Justyn R.; Wheeler, J. Craig; Baade, Dietrich; Patat, Ferdinando; Hoflich, Patat; Wang, Lifan F.; Clocchiatti, Alejandro (2009-11)
      Spectropolarimetry of the Type Ib SN 2008D, associated with the X-ray Flash (XRF) 080109, at two separate epochs, is presented. The epochs of these observations correspond to V-band light curve maximum and 15 days after ...

Craig; Wood-Vasey, Michael; Woosley, Stanford E.; Yamaoka, Hitoshi (2012-04)
      We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Surveys on the Hubble Space Telescope. This ...
    • A Spectropolarimetric View On The Nature Of The Peculiar Type I Sn 2005hk 

      Maund, Justyn R.; Wheeler, J. Craig; Wang, Lifan F.; Baade, Dietrich; Clocchiatti, Alejandro; Patat, Ferdinando; Hoflich, Patat; Quinn, Jason; Zelaya, Paula (2010-10)
      We report two spectropolarimetric observations of SN 2005hk, which is a close copy of the "very peculiar" SN 2002cx, showing low peak luminosity, slow decline, high ionization near peak, and an unusually low expansion ...
    • Spectropolarimetry Of The Type IIb Supernova 2001Ig(1) 

      Maund, Justyn R.; Wheeler, J. Craig; Patat, Ferdinando; Wang, Lifan; Baade, Dietrich; Hoflich, Peter A. (2007-12)
      We present spectropolarimetric observations of the Type IIb SN 2001ig in NGC 7424; conducted with the ESO VLT FORS1 on 2001 December 16, 2002 January 3, and 2002 August 16, or 13, 31, and 256 days postexplosion. These ...
    • The Unification of Asymmetry Signatures of Type Ia Supernovae 

      Maund, Justyn R.; Hoflich, Peter; Patat, Ferdinando; Wheeler, J. Craig; Zelaya, P.; Baade, Dietrich; Wang, Lifan; Clocchiatti, Alejandro; Quinn, Jason (2010-12)
      We present a compilation of the geometry measures acquired using optical and IR spectroscopy and optical spectropolarimetry to probe the explosion geometry of Type Ia supernovae (SNe Ia). Polarization measurements are ...
