The Plerionic Supernova Remnant G21.5-0.9 Powered by PSR J1833-1034: New Spectroscopic and Imaging Results Revealed with the Chandra X-ray Observatory

Heather Matheson, Samar Safi-Harb

(Abridged) In 1999, Chandra revealed a 150"-radius X-ray halo surrounding the 40"-radius PWN G21.5-0.9. A 2005 imaging study showed that the halo is limb-brightened, and suggested…

The Deepest Radio Study of the Pulsar Wind Nebula G21.5-0.9: Still No Evidence for the Supernova Shell

Michael F. Bietenholz, Heather Matheson, Samar Safi-Harb +2

We report on sensitive new 1.4-GHz VLA radio observations of the pulsar wind nebula G21.5-0.9, powered by PSR J1833-1034, and its environs. Our observations were targeted at search…

A Multi-wavelength study of 1WGA J1346.5-6255: a new Cas analog unrelated to the background supernova remnant G309.2-00.6

S. Safi-Harb, M. Ribo, Y. Butt +5

1WGA J1346.5-6255 is a ROSAT X-ray source found within the radio lobes of the supernova remnant (SNR) G309.2-00.6. This source also appears to coincide with the bright and early-ty…

The Plerionic Supernova Remnant G21.5-0.9: In and Out

Heather Matheson, Samar Safi-Harb

The absence of a supernova remnant (SNR) shell surrounding the Crab and other plerions (pulsar wind nebulae) has been a mystery for 3 decades. G21.5-0.9 is a particularly intriguin…
