      We present Hubble Space Telescope (HST) observations of the field of the Type IIb supernova (SN) 2011dh in M51 performed at ≈1161 rest-frame days after explosion using the Wide Field Camera 3 and near-UV filters F225W ...
    • Folatelli, Gastón; Van Dyk, Schuyler D.; Kuncarayakti, Hanindyo; Maeda, Keiichi; Bersten, Melina C.; Nomoto, Ken'ichi; Pignata Libralato, Giuliano; Hamuy Wackenhut, Mario; Quimby, Robert M.; Zheng, WeiKang; Filippenko, Alexei V.; Clubb, Kelsey I.; Smith, Nathan; Elias Rosa, Nancy; Foley, Ryan J.; Miller, Adam A. (IOP Publishing, 2016)
      Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observations ...
    • Maeda, Keiichi; Leloudas, Giorgos; Taubenberger, Stefan; Stritzinger, Maximilian; Sollerman, Jesper; Elias Rosa, Nancy; Benetti, Stefano; Hamuy Wackenhut, Mario; Folatelli, Gastón; Mazzali, Paolo (2011)
      Phenomenological relations exist between the peak luminosity and other observables of type Ia supernovae (SNe Ia) that allow one to standardize their peak luminosities. However, several issues are yet to be clarified: ...
    • Kuncarayakti, Hanindyo; Maeda, Keiichi; Bersten, Melina Cecilia; Folatelli, Gastón; Morrell, Nidia; Hsiao, Eric; González Gaitán, Santiago; Anderson, J. P.; Hamuy Wackenhut, Mario; De Jaeger, Thomas; Gutiérrez, C. P.; Kawabata, K. S. (EDP Sciences, 2015)
      Aims. We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done similar to 300 days after the explosion. We discuss them in the ...
    • Folatelli, Gastón; Bersten, Melina C.; Kuncarayakti, Hanindyo; Benvenuto, Omar G.; Maeda, Keiichi; Nomoto, Ken’ichi (IOP Publishing, 2015)
      Hubble Space Telescope observations of the site of the supernova (SN) SN 2008ax obtained in 2011 and 2013 reveal that the possible progenitor object detected in pre-explosion images was in fact multiple. Four point sources ...
    • 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 ...

M.; Parrent, J.; Nakaoka, T.; Moriya, T. J.; Suzuki, A.; Takaki, K.; Ishigaki, M.; Sakon, I.; Tajitsu, A.; Iye, M. (IOP Publishing, 2015)
      We report the late-time evolution of Type IIb supernova (SN IIb) 2013df. SN 2013df showed a dramatic change in its spectral features at similar to 1 yr after the explosion. Early on it showed typical characteristics shared ...
    • 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 ...
