    • THE CARNEGIE SUPERNOVA PROJECT: ANALYSIS OF THE FIRST SAMPLE OF LOW-REDSHIFT TYPE-Ia SUPERNOVAE 
      Folatelli, Gastón; Phillips, M. M.; Burns, Christopher R.; Contreras, Carlos; Hamuy Wackenhut, Mario; Freedman, Wendy L.; Persson, S. E.; Stritzinger, Maximilian; Suntzeff, Nicholas B.; Krisciunas, Kevin; Boldt, Luis; González Tagle, Sergio; Krzeminski, Wojtek; Morrell, Nidia; Roth, Miguel; Salgado, Francisco; Madore, Barry F.; Murphy, David; Wyatt, Pamela; Li, Weidong; Filippenko, Alexei V.; Miller, Nicole (2010-01)
      An analysis of the first set of low-redshift (z < 0.08) Type Ia supernovae (SNe Ia) monitored by the Carnegie Supernova Project between 2004 and 2006 is presented. The data consist of well-sampled, high-precision ...
    • The Carnegie Supernova Project: First Photometry Data Release of Low-Redshift Type Ia Supernovae 
      Contreras, Carlos; Hamuy Wackenhut, Mario; Phillips, M. M.; Folatelli, Gastón; Suntzeff, Nicholas B.; Persson, S. E.; Stritzinger, Maximilian; Boldt, Luis; González Tagle, Sergio; Krzeminski, Wojtek; Morrell, Nidia; Roth, Miguel; Salgado, Francisco; Maureira, María José; Burns, Christopher R.; Freedman, Wendy L.; Madore, Barry F.; Murphy, David; Wyatt, Pamela; Li, Weidong; Filippenko, Alexei V. (2009-10)
      The Carnegie Supernova Project is a five-year survey being carried out at the Las Cam- panas Observatory to obtain high-quality light curves of 100 low-redshift Type Ia supernovae in a well-defined photometric system. ...
    • A new distance to the Antennae galaxies (NGC 4038/39) based on the type Ia supernova 2007sr 
      Schwaizer, Francois; Burns, Christopher R.; Madore, Barry F.; Mager, VIiolet A.; Phillips, M. M.; Freedman, Wendy L.; Boldt, Luis; Contreras, Carlos; Folatelli, Gastón; González Tagle, Sergio; Hamuy Wackenhut, Mario; Krzeminski, Wojtek; Morrell, Nidia; Persson, S. E.; Roth, Miguel; Stritzinger, Maximilian D. (2008-10)
      Traditionally, the distance to NGC 4038/39 has been derived from the systemic recession velocity, yielding about 20 Mpc for H0 = 72 km s-1 Mpc-1. Recently, this widely adopted distance has been challenged based on ...
    • SN 2009bb: A PECULIAR BROAD-LINED TYPE Ic SUPERNOVA 
      Pignata Libralato, Giuliano; Stritzinger, Maximilian; Soderberg, Alicia; Mazzali, Paolo; Phillips, M. M.; Morrell, Nidia; Anderson, Joseph P.; Boldt, Luis; Campillay, Abdo; Contreras, Carlos; Folatelli, Gastón; Förster, Francisco; González Tagle, Sergio; Hamuy Wackenhut, Mario; Krzeminski, Wojtek; Maza Sancho, José; Roth, Miguel; Salgado, Francisco; Levesque, Emily M.; Rest, Armin; Crain, J. Adam; Foster, Andrew C.; Haislip, Joshua B.; Ivarsen, Kevin M.; LaCluyze, Aaron P.; Nysewander, Melissa C.; Reichart, Daniel E. (2011-02-10)
      Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10 to +285 days past B-band maximum. Thanks to ...

Andrea; Boldt, Luis; Salgado, Francisco; Wyatt, Pamela; Olivares E., Felipe; Gal Yam, Avishay; Sako, Masao (The American Astronomical Society, 2013)
      This is the first release of optical spectroscopic data of low-redshift Type Ia supernovae (SNe Ia) by the Carnegie Supernova Project including 604 previously unpublished spectra of 93 SNe Ia. The observations cover a ...
    • UNBURNED MATERIAL IN THE EJECTA OF TYPE Ia SUPERNOVAE 
      Folatelli, Gastón; Phillips, M. M.; Morrell, Nidia; Tanaka, Masaomi; Maeda, Keiichi; Nomoto, Ken’ichi; Stritzinger, Maximilian; Burns, Christopher R.; Hamuy Wackenhut, Mario; Mazzali, Paolo; Boldt, Luis; Campillay, Abdo; Contreras, Carlos; González Tagle, Sergio; Roth, Miguel; Salgado, Francisco; Freedman, W. L.; Madore, Barry F.; Persson, S. E.; Suntzeff, Nicholas B. (2012-01-20)
      The presence of unburned material in the ejecta of normal Type Ia supernovae (SNe Ia) is investigated using early-time spectroscopy obtained by the Carnegie Supernova Project. The tell-tale signature of pristine material from ...
