      Foley, Ryan J.; Filippenko, Alexei V.; Aguilera, C.; Becker, A. C.; Blondin, S.; Challis, P.; Clocchiatti, A.; Covarrubias, R.; Davis, Tamara M.; Garnavich, Peter M.; Jha, S.; Kirshner, Robert P.; Krisciunas, Kevin; Leibundgut, B.; Li, Weidong; Matheson, Thomas; Miceli, A.; Miknaitis, G.; Pignata Libralato, Giuliano; Rest, A.; Riess, A. G.; Schmidt, Brian P.; Smith, R. C.; Sollerman, J.; Spyromilio, J.; Stubbs, C. W.; Tonry, J. L.; Suntzeff, Nicholas B.; Wood-Vasey, W. M.; Zenteno, A. (UNIV CHICAGO PRESS, 2008-09-01)
      We present a large-scale effort of creating composite spectra of high-redshift SNe Ia and comparing them to low-redshift counterparts in an attempt to understand possible cosmic evolution of SNe Ia, which has major ...
    • THE DISTANCES TO 5 TYPE-II SUPERNOVAE USING THE EXPANDING PHOTOSPHERE METHOD, AND THE VALUE OF HO 
      Schmidt, Brian P.; Kirshner, Robert P.; Eastman, Ronald G.; Phillips, Mark M.; Suntzeff, Nicholas B.; Hamuy Wackenhut, Mario; Maza Sancho, José; Avilés, Roberto (UNIV CHICAGO PRESS, 1994-09-01)
      We have used observations gathered at CTIO to measure distances by the expanding photosphere method (EPM) to five Type II supernovae. These supernovae lie at redshifts from cz = 1100 km s-1 to cz - 5500 km s-1, and increase ...
    • THE EXPANDING PHOTOSPHERE METHOD APPLIED TO SN-1992AM AT CZ=14600KM-S 
      Schmidt, Brian P.; Kirshner, Robert P.; Eastman, Ronald G.; Hamuy Wackenhut, Mario; Phillips, Mark M.; Suntzeff, Nicholas B.; Maza Sancho, José; Filippenko, Alexei V.; Ho, Luis C.; Matheson, Thomas; Grashuis, Randy; Aviles, Roberto; Kirkpatrick, J. Davy; Challis, Peter; Kuijken, Konrad; Zucker, Daniel; Bolte, Michael; Tyson, Neil D. (AMER INST PHYSICS, 1994-04)
      We present photometry and spectroscopy of SN 1992am for five months following its discovery by the Calan/CTIO SN search. These data show SN 1992am to be type II-P, displaying hydrogen in its spectrum and the typical shoulder ...
    • Exploring the outer solar system with the ESSENCE Supernova Survey 
      Becker, A. C.; Arraki, K.; Kaib, N. A.; Wood-Vasey, W. M.; Aguilera, C.; Blackman, J. W.; Blondin, S.; Challis, P.; Clocchiatti, A.; Covarrubias, R.; Damke, G.; Davis, Tamara M.; Filippenko, Alexei V.; Foley, Ryan J.; Garg, A.; Garnavich, Peter M.; Hicken, M.; Jha, S.; Kirshner, Robert P.; Krisciunas, Kevin; Leibundgut, B.; Li, Weidong; Matheson, Thomas; Miceli, A.; Miknaitis, G.; Narayan, G.; Pignata Libralato, Giuliano; Prieto, J. L.; Rest, A.; Riess, A. G.; Salvo, M. E.; Schmidt, Brian P.; Smith, R. C.; Sollerman, J.; Spyromilio, J.; Stubbs, C. W.; Suntzeff, Nicholas B.; Tonry, J. L.; Zenteno, A. (UNIV CHICAGO PRESS, 2008-07-20)
      We report the discovery and orbital determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging data set. Two additional objects discovered in a similar search of the SDSS-II ...

      Pignata Libralato, Giuliano; Benetti, Stefano; Mazzali, Paolo; Kotak, Rubina; Patat, F.; Meikle, P.; Stehle, M.; Leibundgut, B.; Suntzeff, Nicholas B.; Buson, L. M.; Cappellaro, E.; Clocchiatti, A.; Hamuy Wackenhut, Mario; Maza Sancho, José; Mendez, J.; Ruiz Lapuente, P.; Salvo, M.; Schmidt, Brian P.; Turatto, M.; Hillebrandt, W. (BLACKWELL PUBLISHING, 2008-08-11)
      As part of the European Supernova Collaboration, we obtained extensive photometry and spectroscopy of the Type Ia supernova (SN Ia) SN 2002dj covering epochs from 11 d before to nearly two years after maximum. Detailed ...
    • SN 1991bg - A type IA supernova with a difference 
      Leibundgut, Bruno; Kirshner, Robert P.; Phillips, Mark M.; Wells, Lisa A.; Suntzeff, Nicholas B.; Hamuy Wackenhut, Mario; Schommer, R. A.; Walker, A. R.; Gonzalez, L.; Ugarte, P.; Williams, R. E.; Williger, G.; Gómez, Mercedes; Marzke, Ronald; Schmidt, Brian P.; Whitney, Barbara; Coldwell, Nelson; Peters, J.; Chaffee, F. H.; Foltz, Craig B.; Rehner, D.; Siciliano, L.; Barnes, T.

      We present 13 spectra and 31 photometric observations covering the first 150 days of SN 1991bg in NGC 4374 (M 84). Although SN 1991bg was a type Ia supernova displaying the characteristic Si II absorption at 6150 angstrom ...
