    • Constraining cosmic evolution of type Ia supernovae 
      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 ...
    • 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 ...
    • Optical photometry of the type Ia supernova 1999ee and the type Ib/c supernova 1999ex in IC 5179 
      Stritzinger, Maximiliam; Hamuy Wackenhut, Mario; Suntzeff, Nicholas B.; Smith, R. C.; Phillips, M. M.; Maza Sancho, José; Strolger, L. G.; Antezana, Roberto; González, Luis; Wischnjewsky, Marina; Candia, Pablo; Espinoza, Juan; González, David; Stubbs, Christopher; Becker, A. C.; Rubenstein, Eric P.; Galaz, Gaspar, 1967- (2002-10)
      We present UBVRIz light curves of the Type Ia SN 1999ee and the Type Ib/c SN 1999ex, both located in the galaxy IC 5179. SN 1999ee has an extremely well-sampled light curve spanning from 10 days before Bmax through 53 ...
    • Spectral identification of an ancient supernova using light echoes in the Large Magellanic Cloud 
      Rest, A.; Matheson, Thomas; Blondin, S.; Bergmann, M.; Welch, D. L.; Suntzeff, Nicholas B.; Smith, R. C.; Olsen, K.; Prieto, J. L.; Garg, A.; Challis, P.; Stubbs, C.; Hicken, M.; Modjaz, Maryam; Wood-Vasey, W. M.; Zenteno, A.; Damke, G.; Newman, A.; Huber, M.; Cook, K. H.; Nikolaev, S.; Becker, A. C.; Miceli, A.; Covarrubias, R.; Morelli, L.; Pignata Libralato, Giuliano; Clocchiatti, A.; Minniti, D.; Foley, Ryan J. (UNIV CHICAGO PRESS, 2008-06-20)
      We report the successful identification of the type of the supernova responsible for the supernova remnant SNR 0509-675 in the Large Magellanic Cloud (LMC) using Gemini spectra of surrounding light echoes. The ability ...

C.; Spyromilio, J.; Stritzinger, M.; Stubbs, C. W.; Suntzeff, Nicholas B.; Tonry, J. L.; Tucker, B. E.; Zenteno, A. (UNIV CHICAGO PRESS, 2008-08-01)
      We present multiepoch spectra of 13 high-redshift Type Ia supernovae (SNe Ia) drawn from the literature, the ESSENCE and SNLS projects, and our own separate dedicated program on the ESO Very Large Telescope. We use the ...
