    • Carnegie Supernova Project II: The Slowest Rising Type Ia Supernova LSQ14fmg and Clues to the Origin of ... 
      Hsiao, E. Y.; Hoeflich, P.; Ashall, C.; Lu, J.; Contreras, C.; Burns, C. R.; Phillips, M. M.; Galbany, L.; Anderson, J. P.; Baltay, C.; Baron, E.; Castellón, S.; Davis, S.; Freedman, Wendy L.; Gall, C.; González, C.; Graham, M. L.; Hamuy Wackenhut, Mario; Holoien, T. W.-S.; Karamehmetoglu, E.; Krisciunas, K.; Kumar, S.; Kuncarayakti, H.; Morrell, N.; Moriya, T. J.; Nugent, P. E.; Perlmutter, S.; Persson, S. E.; Piro, A. L.; Rabinowitz, D.; Roth, M.; Shahbandeh, M.; Shappee, B. J.; Stritzinger, M. D.; Suntzeff, N. B.; Taddia, F.; Uddin, S. A. (IOP Publishing, 2020)
      The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties that may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum is typical of a 03fg-like SN Ia, but the ...
    • Observed type II supernova colours from the carnegie supernova project-I 
      De Jaeger, Thomas; Anderson, J. P.; Galbany, Lluis; González Gaitán, Santiago; Hamuy Wackenhut, Mario; Phillips, M. M.; Stritzinger, M. D.; Contreras, C.; Folatelli, Gastón; Gutiérrez, C. P.; Hsiao, E. Y.; Morrell, N.; Suntzeff, Nicholas B.; Dessart, L.; Filippenko, A. V. (Oxford University Press, 2018-06)
      We present a study of observed Type II supernova (SN II) colours using optical/near-infrared photometric data from the Carnegie Supernovae Project-I. We analyse four colours (B - V, u - g, g - r, and g - Y) and find that ...
    • The Emergence of the Infrared Transient VVV-WIT-06 
      Minniti, D.; Saito, R. K.; Forster, Francisco; Pignata Libralato, Giuliano; Ivanov, V. D.; Lucas, P. W.; Beamin, J. C.; Borissova, J.; Catelan, M.; González, O. A.; Hempel, M.; Hsiao, E. Y.; Kurtev, R.; Majaess, D.; Masetti, N.; Morrell, N. I.; Phillips, M. M.; Pullen, J. B.; Rejkuba, M.; Smith, L.; Surot, F.; Valenti, E.; Zoccali, M. (Institute of Physics, 2017)
      We report the discovery of an enigmatic large-amplitude (DKs > 10.5 mag) transient event in near-IR data obtained by the VISTA Variables in the Via Lactea (VVV) ESO Public Survey. The object (designated VVV-WIT- 06) is ...
    • Type II supernovae from the Carnegie Supernova Project-I I. Bolometric light curves of 74 SNe II using ... 
      Martínez, L.; Bersten, M. C.; Anderson, J. P.; Hamuy, M.; González Gaitán, S.; Stritzinger, M.; Phillips, M. M.; Gutiérrez, C. P.; Burns, C.; Contreras, C.; De Jaeger, T.; Ertini, K.; Folatelli, G.; Forster Burón, Francisco; Galbany, L.; Hoeflich, P.; Hsiao, E. Y.; Morrell, N.; Orellana, M.; Pessi, P. J.; Suntzeff, N. B. (EDP Sciences, 2022)
      The present study is the first of a series of three papers where we characterise the type II supernovae (SNe II) from the Carnegie Supernova Project-I to understand their diversity in terms of progenitor and explosion ...
    • Type II supernovae from the Carnegie Supernova Project-I II. Physical parameter distributions from ... 
      Martínez, L.; Bersten, M. C.; Anderson, J. P.; Hamuy, M.; González Gaitán, S.; Forster Burón, Francisco; Orellana, M.; Stritzinger, M.; Phillips, M. M.; Gutiérrez, C. P.; Burns, C.; Contreras, C.; De Jaeger, T.; Ertini, K.; Folatelli, G.; Galbany, L.; Hoeflich, P.; Hsiao, E. Y.; Morrell, N.; Pessi, P. J.; Suntzeff, N. B. (EDP, 2022)
      Linking supernovae to their progenitors is a powerful method for furthering our understanding of the physical origin of their observed differences while at the same time testing stellar evolution theory. In this second ...
    • Type II supernovae from the Carnegie Supernova Project-I III. Understanding SN II diversity through ... 
      Martínez, L.; Anderson, J. P.; Bersten, M. C.; Hamuy, M.; González Gaitán, S.; Orellana, M.; Stritzinger, M.; Phillips, M. M.; Gutiérrez, C. P.; Burns, C.; De Jaeger, T.; Ertini, K.; Folatelli, G.; Forster Burón, Francisco; Galbany, L.; Hoeflich, P.; Hsiao, E. Y.; Morrell, N.; Pessi, P. J.; Suntzeff, N. B. (EDP, 2022)
      Type II supernovae (SNe II) show great photometric and spectroscopic diversity which is attributed to the varied physical characteristics of their progenitor and explosion properties. In this study, the third of a series ...
