Autor: Folatelli, Gastón Van Dyk, Schuyler D. Kuncarayakti, Hanindyo Maeda, Keiichi Bersten, Melina C. Nomoto, Ken'ichi Pignata, Giuliano Hamuy, Mario Quimby, Robert M. Zheng, WeiKang Filippenko, Alexei V. Clubb, Kelsey I. Smith, Nathan Elias-Rosa, Nancy Foley, Ryan J. Miller, Adam A.

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 of the SN site similar to 740 days after explosion. We detect an object i...

Evidence for asymmetric distribution of circumstellar material around type ia supernovae.

Autor: Forster, Francisco González–Gaitán, Santiago Anderson, Joseph Marchi, Sebastián Gutiérrez, Claudia P. Hamuy, Mario Pignata, Giuliano Cartier, Régis

ABSTRACT We study the properties of low–velocitymaterial in the line of sight towards nearby Type Ia Supernovae (SNe Ia) that have measured late phase nebular velocity shifts (vneb), thought to be an environment–independent observable. We have found that the distribution of equivalent widths of n...

On the progenitor and supernova of the sn 2002cx-like supernova 2008ge

Autor: Foley, Ryan J. Rest, Armin Stritzinger, Maximilian Pignata, Giuliano Anderson, Joseph P. Hamuy, Mario Morrell, Nidia I. Phillips, Mark M. Salgado, Francisco

We present observations of supernova (SN) 2008ge, which is spectroscopically similar to the peculiar SN 2002cx, and its pre-explosion site that indicate that its progenitor was probably a white dwarf. NGC 1527, the host galaxy of SN 2008ge, is an S0 galaxy with no evidence of star formation or ma...

The Araucaria Project. First Cepheid Distance to the Sculptor Group Galaxy NGC 7793 from Variables discovered in a Wide-Field Imaging Survey

Autor: Pietrzynski, Grzegorz Gieren, Wolfgang Hamuy, Mario Pignata, Giuliano Soszynski, Igor Udalski, Andrzej Walker, Alistair Fouque, Pascal Bresolin, Fabio Kudritzki, Rolf-Peter

We have detected, for the first time, Cepheid variables in the Sculptor Group spiral galaxy NGC 7793. From wide-field images obtained in the optical V and I bands on 56 nights in 2003-2005, we have discovered 17 long-period (24-62 days) Cepheids whose periods and mean magnitudes define tight per...

Supernova 2008bk and its red supergiant progenitor

Autor: Van Dyk, D. Schuyler Davidge, Tim J. Elias-Rosa, Nancy Taubenberger, Stefan Weidong, Li Levesque, Emily M. Stanley, Howerton Morrell, Nidia Hamuy, Mario Filippenko, Alexei V.

Hemos obtenido pocos datos fotométricos y espectroscópicos de supernova (SN) 2008bk en NGC 7793, principalmente a 150 días después de la explosión. Nos parece que se trata de un tipo II-Plateau (II-P) SN que más se asemeja a la de baja luminosidad SN 1999br en NGC 4900. Dada la similitud general ...

A study of the color diversity around maximum light in Type Ia supernovae

Autor: Cartier, Regis Foster, Francisco Coppi, Paolo Hamuy, Mario Maeda, Keiichi Pignata, Guiliano Folatelli, Gastón

From a sample of 12 well-observed Type Ia supernovae, we ﬁnd clear evidence of correlations between early phase (U − B), (V − R), and (V − I) colors and the velocity shifts of the [Fe II] λ7155 and [Ni II] λ7378 nebular lines measured from late-phase spectra. As these lines are thought to trace t...
