    • Supernova 2010as: the lowest-velocity member of a family of flat-velocity type IIb supernovae 
      Folatelli, Gastón; Bersten, Melina C.; Kuncarayakti, Hanindyo; Olivares Estay, Felipe; Anderson, Joseph P.; Holmbo, Simon; Maeda, Keiichi; Morrell, Nidia; Nomoto, Ken’ichi; Pignata Libralato, Giuliano; Stritzinger, Maximilian; Contreras, Carlos; Forster, Francisco; Hamuy Wackenhut, Mario; Phillips, Mark M.; Prieto, José Luis; Valenti, Stefano; Afonso, Paulo; Altenmuller, Konrad; Elliott, Jonny; Greiner, Jochen; Updike, Adria; Haislip, Joshua B.; LaCluyze, Aaron P.; Moore, Justin P.; Reichart, Daniel E. (The American Astronomical Society, 2014-09-01)
      We present extensive optical and near-infrared photometric and spectroscopic observations of the stripped-envelope supernova SN 2010as. Spectroscopic peculiarities such as initially weak helium features and low ...
    • The peculiar SN 2005hk: Do some type ia supernovae explode as deflagrations? 
      Phillips, Mark M.; Li, Weidong; Frieman, Joshua A.; Blinnikov, Sergei; DePoy, Darren; Prietro, Jose L.; Milne, P.; Contreras, Carlos; Folatelli, Gastón; Morrell, Nidia; Hamuy Wackenhut, Mario; Suntzeff, Nicholas B.; Roth, Miguel; Krzeminski, Wojtek; Filippenko, Alexei V.; Freedman, Wendy L.; Chornock, Ryan; Jha, Saurabh; Madore, Barry F.; Persson, S. E.; González Tagle, Sergio; Burns, Christopher R.; Wyatt, Pamela; Murphy, David; Foley, Ryan J.; Ganeshalingam, Mohan; Serduke, Franklin J. D.; Krisciunas, Kevin; Bassett, Bruce; Becker, Andrew; Dilday, Ben; Eastman, J.; Garnavich, Peter M.; Holtzman, Jon; Kessler, Richard; Lampeitl, Hubert; Marriner, John; Frank, S.; Marshall, J. L.; Miknaitis, Gajus; Sako, Masao; Schneider, Donald P.; Van Der Heyden, Kurt; Yasuda, Naoki (2007)
      We present extensive u'g'r'i'BVRIYJHK(s) photometry and optical spectroscopy of the Type Ia supernova ( SN) 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002cx, which has ...
    • The Standardizability of Type Ia Supernovae in the Near-Infrared: Evidence for a Peak-Luminosity Versus ... 
      Kattner, ShiAnne; Leonard, Douglas C.; Burns, Christopher R.; Phillips, M. M.; Folatelli, Gastón; Morrell, Nidia; Stritzinger, Maximilian D.; Hamuy Wackenhut, Mario; Freedman, Wendy L.; Persson, Sven E.; Roth, Miguel; Suntzeff, Nicholas B. (UNIV CHICAGO PRESS, 2012-02)
      We analyze the standardizability of Type Ia supernovae (SNe Ia) in the near-infrared (NIR) by investigating the correlation between observed peak NIR (Y JH) absolute magnitude and postmaximum B-band decline rate [Delta ...
    • UBVRIz Light Curves of 51 Type II Supernovae 
      Galbany, Lluis; Hamuy Wackenhut, Mario; Phillips, Mark M.; Suntzeff, Nicholas B.; Maza Sancho, José; De Jaeger, Thomas; Moraga, Tania; González Gaitán, Santiago; Krisciunas, Kevin; Morrell, Nidia; Thomas Osip, Joanna; Krzeminski, Wojtek; Gonzalez, Luis; Antezana, Roberto; Wishnjewski, Marina; McCarthy, Patrick; Anderson, Joseph; Gutierrez, Claudia; Stritzinger, Maximilian; Folatelli, Gastón; Anguita, Claudio; Galaz, Gaspar, 1967-; Green, Elisabeth; Impey, Chris; Kim, Yong-Cheol; Kirhakos, Sofia; Malkan, Mathew; Mulchaey, John; Phillips, Andrew; Pizzella, Alessandro; Prosser, Charles; Schmidt, Brian; Schommer, Robert; Sherry, William; Strolger, Louis; Wells, Lisa; Williger, Gerard (OP PUBLISHING, 2016)
      We present a compilation of UBVRIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986-2003: the Cerro Tololo Supernova Survey, the Calan/Tololo Supernova Program (C&T), ...
    • 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 ...
