SN 2012ec: Mass of the progenitor from PESSTO follow-up of the photospheric phase
(Oxford University Press, 2015-04)
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 ...
SN 2012ec: mass of the progenitor from PESSTO follow-up of the photospheric phase

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 ...
Supernova progenitors, their variability and the Type IIP Supernova ASASSN-16fq in M66
(OXFORD UNIV PRESS, 2017)
We identify a pre-explosion counterpart to the nearby Type IIP supernova ASASSN-16fq (SN 2016cok) in archival Hubble Space Telescope data. The source appears to be a blend of several stars that prevents obtaining accurate ...
Ultraviolet diversity of type Ia supernovae
(Oxford University Press, 2016-09)
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 ...
SN 2012fr: ultraviolet, optical, and near-infrared light curves of a type Ia supernova observed within a day of explosion
(The American Astronomical Society, 2018-05-20)
We present detailed ultraviolet, optical, and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise high-cadence light curves provide a dense ...
Mass discrepancy analysis for a select sample of Type II-Plateau supernovae
(EDP Sciences, 2019-09-16)
The detailed study of supernovae (SNe) and their progenitors allows a better understanding of the evolution of massive stars and how these end their lives. Despite its importance, the range of physical parameters for the ...
Possible evidence of asymmetry in SN 2007rt, a type IIn supernova
(EDP SCIENCES S A, 2009)
An optical photometric and spectroscopic analysis of the slowly-evolving type IIn SN 2007rt is presented, covering a duration of 481 days after discovery. Its earliest spectrum, taken approximately 100 days after the ...
Comprehensive observations of the bright and energetic Type lax SN 2012Z: Interpretation as a Chandrasekhar mass white dwarf explosion
(EDP Sciences, 2015)
We present ultraviolet through near-infrared (NIR) broadband photometry, and visual-wavelength and NIR spectroscopy of the Type lax supernova (SN) 2012Z. The data set consists of both early- and late-time observations, ...
