Nebular phase observations of the type-Ib supernova iPTF13bvn favour a binary progenitor
(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 ...
The Carnegie Supernova Project I photometry data release of low-redshift stripped envelope supernovae
(EDP Sciences, 2018)
The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and ...
DES15E2mlf: a spectroscopically confirmed superluminous supernova that exploded 3.5 Gyr after the big bang
(Oxford University Press, 2017)
We present the Dark Energy Survey (DES) discovery of DES15E2mlf, the most distant superluminous supernova (SLSN) spectroscopically confirmed to date. The light curves and Gemini spectroscopy of DES15E2mlf indicate that it ...
Supernova 2010ev: A reddened high velocity gradient type Ia supernova
(EDP Sciences, 2016)
Aims. We present and study the spectroscopic and photometric evolution of the type Ia supernova (SN Ia) 2010ev. Methods. We obtain and analyze multiband optical light curves and optical/near-infrared spectroscopy at low ...
On the multiplicity of supernovae within host galaxies
(EDP Sciences, 2013)
Aims. We investigate the nature of multiple supernova hosting galaxies, and the types of events that they produce. Methods. Using all known historical supernovae, we split host galaxies into samples containing single or ...
Optical photometry and spectroscopy of the 1987A-like supernova 2009mw
(Oxford Univ. Press, 2016)
We present optical photometric and spectroscopic observations of the 1987A-like supernova (SN) 2009mw. Our BVRI and g ' r ' i ' z ' photometry covers 167 d of evolution, including the rise to the light-curve maximum, and ...
Supernovae: Where and why do they break off?
(SABER ULA, 2005)
The explosion of supernova 2011fe in the frame of the core-degenerate scenario (Letter)
We argue that the properties of the Type Ia supernova (SN Ia) SN 2011fe can be best explained within the frame of the core-degenerate (CD) scenario. In the CD scenario, a white dwarf (WD) merges with the core of an asymptotic ...
Observational constraints on the progenitor metallicities of core-collapse supernovae
(Royal Astronomical Society, 2010)
We present constraints on the progenitor metallicities of core-collapse supernovae. To date, nearly all metallicity constraints have been inferred from indirect methods such as metallicity gradients in host galaxies, ...
