Luminous Type II supernovae for their low expansion velocities
(Oxford University Press, 2020)
We present optical and near-infrared data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of early interaction of the ejecta with ...
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 ...
Evolving into a remnant: optical observations of SN 1978K at three decades
(Oxford Univ Press, 2016)
We present new optical observations of the supernova SN 1978K, obtained in 2007 and 2014 with the Very Large Telescope. We discover that the supernova has not faded significantly, even more than three decades after its ...
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 ...
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 ...
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 ...
SN 2012ec: mass of the progenitor from PESSTO follow-up of the photospheric phase
(Oxford Univ Press, 2015)
We present the results of a photometric and spectroscopic monitoring campaign of SN 2012ec, which exploded in the spiral galaxy NGC 1084, during the photospheric phase. The photometric light curve exhibits a plateau with ...
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, ...
A comparative study of Type II-P and II-L supernova rise times as exemplified by the case of LSQ13cuw
(EDP Sciences, 2015)
We report on our findings based on the analysis of observations of the Type II-L supernova LSQ13cuw within the framework of
currently accepted physical predictions of core-collapse supernova explosions. LSQ13cuw was ...
