The GRB 060218/SN 2006aj event in the context of other Gamma-Ray Burst Supernovae
The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033). We present Very Large Telescope, Liverpool Telescope, and Katzman Automatic Imaging Telescope multi-color photometry of SN 2006aj. This supernova is found to be subluminous and rapidly evolving. Its early light curve includes an additional wavelength-dependent component, which can be inte...
متن کاملGRB 060218/SN 2006aj: prompt emission from inverse-Compton scattering of shock breakout thermal photons
The γ-ray burst (GRB) 060218/SN 2006aj is a peculiar event, with the second lowest redshift, low luminosity, long duration, chromatic lightcurve features, and in particular, the presence of a thermal component in the X-ray and UVoptical spectra. Thanks to detailed temporal and spectral coverage of the Swift observatory, the abundant data allow the GRB prompt emission to be modelled in great det...
متن کاملShock Breakout in Type Ibc Supernovae and Application to GRB 060218/SN 2006aj
Recently, a soft black-body component was observed in the early X-ray afterglow of GRB 060218, which was interpreted as shock breakout from the thick wind of the progenitor Wolf-Rayet (WR) star of the underlying Type Ic SN 2006aj. In this paper we present a simple model for computing the characteristic quantities (including energy, temperature, and time-duration) for the transient event from th...
متن کاملThe nature of the dwarf starforming galaxy associated with GRB 060218 / SN 2006 aj ⋆
Context. We present high resolution VLT UVES and low resolution FORS optical spectroscopy of supernova 2006aj and its host galaxy, associated with the nearby (z = 0.03342) gamma-ray burst GRB 060218. This host galaxy is a unique case, as it is one of the few nearby GRB host galaxies known, and it is only the second time high resolution spectra have been taken of a nearby GRB host galaxy (after ...
متن کاملSn 2006aj Associated with Xrf 060218 at Late Phases: Nucleosynthesis-signature of a Neutron Star-driven Explosion
Optical spectroscopy and photometry of SN 2006aj have been performed with the Subaru telescope at t > 200 days after GRB060218, the X-ray Flash with which it was associated. Strong nebular emission-lines with an expansion velocity of v ∼ 7, 300 km s were detected. The peaked but relatively broad [OI]λλ6300, 6363 suggests the existence of ∼ 2M⊙ of materials in which ∼ 1.3M⊙ is oxygen. The core m...
