The (Re-)Discovery of G350.1-0.3: A Young, Luminous Supernova Remnant and Its Neutron Star
B. M. Gaensler, A. Tanna, P. O. Slane +6
We present an XMM-Newton observation of the long-overlooked radio source G350.1-0.3. The X-ray spectrum of G350.1-0.3 can be fit by a shocked plasma with two components: a high-tem…
Discovery of 35 New Supernova Remnants in the Inner Galaxy
C. L. Brogan, J. D. Gelfand, B. M. Gaensler +2
We report the discovery of up to 35 new supernova remnants (SNRs) from a 42 arcsec resolution 90cm multi-configuration Very Large Array survey of the Galactic plane covering 4.5 de…
Discovery of a Radio Supernova Remnant and Non-thermal X-rays Coincident with the TeV Source HESS J1813-178
C. L. Brogan, B. M. Gaensler, J. D. Gelfand +4
We present the discovery of non-thermal radio and X-ray emission positionally coincident with the TeV -ray source HESS J1813--178. We demonstrate that the non-thermal radio emis…
A Re-brightening of the Radio Nebula associated with the 2004 December 27 giant flare from SGR 1806--20
J. D. Gelfand, Y. E. Lyubarsky, D. Eichler +7
The 2004 Dec. 27 giant Gamma-ray flare detected from the magnetar SGR 1806-20 created an expanding radio nebula which we have monitored with the Australia Telescope Compact Array a…
Diagnosing the outflow from the SGR 1806-20 Giant Flare with Radio Observations
J. Granot, E. Ramirez-Ruiz, G. B. Taylor +6
On 2004 Dec. 27, the soft gamma repeater (SGR) 1806-20 emitted the brightest giant flare (GF) ever detected from an SGR, with an (isotropic) energy release times greater…
An expanding radio nebula produced by a giant flare from the magnetar SGR 1806-20
B. M. Gaensler, C. Kouveliotou, J. D. Gelfand +16
Soft gamma repeaters (SGRs) are "magnetars", a small class of slowly spinning neutron stars with extreme surface magnetic fields, ~10^15 gauss. On 2004 December 27, a giant flare w…
