The composite form of the supernova remnant 3C 400.2: Two interacting supernova remnants or a single supernova remnant with a blow-out?
(2006)
3C 400.2 is a galactic supernova remnant with a complex morphology consisting of two overlapping shells of different diameters: a large shell to the southeastern side and a small shell to the northwestern side. In order ...

Three-dimensional hydrodynamical simulations of the large scale structure of W50-SS433
(Oxford University Press, 2008-12)
We present 3D hydrodynamical simulations of a precessing jet propagating inside a supernova remnant (SNR) shell, particularly applied to the W50-SS433 system in a search for the origin of its peculiar elongated morphology. ...
Cosmic-Ray Acceleration at the Forward Shock in Tycho's Supernova Remnant: Evidence from Chandra X-Ray Observations
(IOP Publishing, 2005-12)
We present evidence for cosmic-ray acceleration at the forward shock in Tycho's supernova remnant (SNR) from three X-ray observables: (1) the proximity of the contact discontinuity to the forward shock, or blast wave, (2) ...
Spectral Identification of an Ancient Supernova Using Light Echoes in the Large Magellanic Cloud
(2008)
We report the successful identification of the type of the supernova responsible for the supernova remnant SNR 0509-675 in the Large Magellanic Cloud (LMC) using Gemini spectra of surrounding light echoes. The ability to ...
Supernovae: Where and why do they break off?

Local star formation triggered by supernova shocks in magnetized diffuse neutral clouds
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
In this work, considering the impact of a supernova remnant (SNR) with a neutral magnetized cloud we derived analytically a set of conditions that are favourable for driving gravitational instability in the cloud and thus ...
A multi-wavelength study of the western lobe of W50 powered by the galactic microquasar SS 433
(Elsevier, 2005-12)
W50 remains the only supernova remnant (SNR) confirmed to harbor a microquasar: the powerful enigmatic source SS 433. Our past study of this fascinating SNR revealed two X-ray lobes distorting the radio shell as well ...
Feature-tailored spectroscopic analysis of the SNRsupernova remnant Puppis A in X-rays
(EDP Sciences, 2016-05)
We introduce a distinct method to perform spatially-resolved spectral analysis of astronomical sources with highly structured X-ray emission. The method measures the surface brightness of neighbouring pixels to adaptively ...
Accounting for the foreground contribution to the dust emission towards Kepler's supernova remnant
(Wiley Blackwell Publishing, Inc, 2009-12)
Whether or not supernovae contribute significantly to the overall dust budget is a controversial subject. Submillimetre (sub-mm) observations, sensitive to cold dust, have shown an excess at 450 and 850 µm in young remnants ...
