On the progenitor and supernova of the sn 2002cx-like supernova 2008ge
(2010)
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 ...
A HUBBLE DIAGRAM FROM TYPE II SUPERNOVAE BASED SOLELY ON PHOTOMETRY: THE PHOTOMETRIC COLOR METHOD
(IOP PUBLISHING, 2015-12)
We present a Hubble diagram of SNe II using corrected magnitudes derived only from photometry, with no input of spectral information. We use a data set from the Carnegie Supernovae Project I for which optical and near-infrared ...
Pan-STARRS and PESSTO search for an optical counterpart to the LIGO gravitational-wave source GW150914
(OXFORD UNIV PRESS, 2016-11)
We searched for an optical counterpart to the first gravitational-wave source discovered by LIGO (GW150914), using a combination of the Pan-STARRS1 wide-field telescope and the Public ESO Spectroscopic Survey of Transient ...
Supernova 2013fc in a circumnuclear ring of a luminous infrared galaxy: The big brother of SN 1998S
(OXFORD UNIV PRESS, 2016-02)
We present photometric and spectroscopic observations of SN 2013fc, a bright type II supernova (SN) in a circumnuclear star-forming ring in the luminous infrared galaxy ESO 154-G010, observed as part of the Public ESO ...
LSQ13fn: A type II-Plateau supernova with a possibly low metallicity progenitor that breaks the standardised candle relation
(EDP SCIENCES, 2016-04)
We present optical imaging and spectroscopy of supernova (SN) LSQ13fn, a type II supernova with several hitherto-unseen properties. Although it initially showed strong symmetric spectral emission features attributable to ...
Ultraviolet diversity of Type Ia Supernovae
(OXFORD UNIV PRESS, 2016-06)
Ultraviolet (UV) observations of Type Ia supernovae (SNe Ia) probe the outermost layers of the explosion, and UV spectra of SNe Ia are expected to be extremely sensitive to differences in progenitor composition and the ...
Optical photometry and spectroscopy of the 1987A-like supernova 2009mw
(OXFORD UNIV PRESS, 2016-08)
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 ...
THE HIGH CADENCE TRANSIENT SURVEY (HITS). I. SURVEY DESIGN AND SUPERNOVA SHOCK BREAKOUT CONSTRAINTS
(Universidad Andrés Bello, 2016-12)
We present the first results of the High Cadence Transient Survey (HiTS), a survey for which the objective is to detect and follow-up optical transients with characteristic timescales from hours to days, especially the ...
LIGHT CURVES OF 213 TYPE Ia SUPERNOVAE FROM THE ESSENCE SURVEY
(IOP PUBLISHING, 2016)
The ESSENCE survey discovered 213 Type Ia supernovae at redshifts 0.1 < z < 0.81 between 2002 and 2008. We present their R- and I-band photometry, measured from images obtained using the MOSAIC II camera at the CTIO Blanco, ...
