The Vela Pulsar Wind Nebula at 6cm
Observations using the Australia Telescope Compact Array at a wavelength of 6 cm have uncovered the radio counterpart to the compact X-ray nebula surrounding the Vela pulsar. Two lobes were found oriented about the spin axis of the pulsar, starting at the edge of X-ray emission, they extend to three times the size. The northern lobe has a bright, defined edge and an integrated flux of 0.14 Jy, ...
متن کاملSupernova Remnant and Pulsar Wind Nebula Interactions
I review several topics in the structure of supernova remnants. Hydrodynamic instabilities in young remnants may give rise to the cellular structure that is sometimes observed, although structure in the ejecta might also play a role. The presence of ejecta close to the forward shock front of a young remnant can be the result of ejecta clumps or the dynamical effects of cosmic rays. Slower movin...
متن کاملA Spin-down Power Threshold for Pulsar Wind Nebula Generation?
A systematic X-ray survey of the most energetic rotationpowered pulsars known, based on spin-down energy loss rate, Ė = Iωω̇, shows that all energetic pulsars with Ė > Ėc ≈ 3.4 × 10 36 erg s are X-ray bright, manifest a distinct pulsar wind nebula (PWN), and are associated with a supernova event, either historically or via a thermal remnant, with over half residing in shell-like supernova remnan...
متن کاملX-ray Thread G0.13-0.11: A Pulsar Wind Nebula?
We have examined Chandra observations of the recently discovered X-ray thread G0.13-0.11 in the Galactic center Radio Arc region. Part of the Chandra data was studied by Yusef-Zadeh, Law, & Wardle (2002), who reported the detection of 6.4-keV line emission in this region. We find, however, that this line emission is not associated with G0.13-0.11. The X-ray spectrum of G0.13-0.11 is well charac...
متن کاملFaint X-ray Structure in the Crab Pulsar-wind Nebula
We report on a Chandra observation of the Crab Nebula that gives the first clear view of the faint boundary of the Crab's X-ray-emitting Pulsar Wind Neb-ula, or PWN. There is structure in all directions. Fingers, loops, bays, and the South Pulsar Jet all indicate that either filamentary material or the magnetic field are controlling the relativistic electrons. In general, spectra soften as dist...
