LS 5039: A runaway microquasar ejected from the galactic plane
(EDP Sciences, 2002-03)
We have compiled optical and radio astrometric data of the microquasar LS 5039 and derived its proper motion. This, together with the distance and radial velocity of the system, allows us to state that this source is ...
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, ...
