      Carrasco Davis, Rodrigo Antonio; Reyes, E.; Valenzuela, C.; Foerster, F.; Estévez Valencia, Pablo Antonio; Pignata, G.; Bauer, F. E.; Reyes, I.; Sánchez Sáez, P.; Cabrera Vives, G.; Eyheramendy, S.; Catelan, M.; Arredondo, J.; Castillo Navarrete, E.; Rodríguez Mancini, D.; Ruz Mieres, Daniela Valentina; Moya, A.; Sabatini Gacitúa, Luis Alfredo; Sepúlveda Cobo, Cristóbal Mario; Mahabal, A. A.; Silva Farfán, Javier Ignacio; Camacho Iñiguez, E.; Galbany, L. (IOP, 2021)
      We present a real-time stamp classifier of astronomical events for the Automatic Learning for the Rapid Classification of Events broker, ALeRCE. The classifier is based on a convolutional neural network, trained on alerts ...

      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 ...
    • Intermediate-luminosity red transients: spectrophotometric properties and connection to electron-capture ...

Sagues; Smith, K. W.; Sollerman, J.; Somero, A.; Wang, B.; Young, D. R. (EDP, 2021)
      We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They share common observational properties and ...

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 ...

      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 ...

      Martínez, L.; Anderson, J. P.; Bersten, M. C.; Hamuy, M.; González Gaitán, S.; Orellana, M.; Stritzinger, M.; Phillips, M. M.; Gutiérrez, C.
