Probing the Nature of the Vela X Cocoon
Stephanie M. LaMassa, Patrick O. Slane, Okkie C. de Jager
Vela X is a pulsar wind nebula (PWN) associated with the active pulsar B0833-45 and contained within the Vela supernova remnant (SNR). A collimated X-ray filament ("cocoon") extend…
Probing the radio to X-ray connection of the Vela X PWN with Fermi LAT and H.E.S.S
O. C. de Jager, P. O. Slane, S. LaMassa
Morphologically it appears as if the Vela X PWN consists of two emission regions: whereas X-ray (1 keV) and very high energy (VHE) H.E.S.S. gamma-ray observations appear to define…
X-ray Properties of the GigaHertz-Peaked and Compact Steep Spectrum Sources
Aneta Siemiginowska, Stephanie LaMassa, Thomas L. Aldcroft +2
We present {\it Chandra} X-ray Observatory observations of Giga-Hertz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) radio sources. The {\it Chandra} sample contains 13 qua…
