Are oxygen and neon enriched in PNe and is the current solar Ne/O abundance ratio underestimated?
W. Wang, X. -W. Liu
A thorough critical literature survey has been carried out for reliable measurements of oxygen and neon abundances of planetary nebulae (PNe) and HII regions. By contrasting the re…
Elemental abundances of Galactic bulge planetary nebulae from optical recombination lines
W. Wang, X. -W. Liu
(abridged) Deep long-slit optical spectrophotometric observations are presented for 25 Galactic bulge planetary nebulae (GBPNe) and 6 Galactic disk planetary nebulae (GDPNe). The s…
Could electron-positron annihilation lines in the Galactic center result from pulsar winds?
W. Wang, C. S. J. Pun, K. S. Cheng
we study the possibility of pulsar winds in the Galactic center (GC) to produce the 511 keV line. We propose that there may exist three possible scenarios of pulsar winds as the po…
Possible TeV Source Candidates In The Unidentified EGRET Sources
W. Wang, Z. J. Jiang, C. S. J. Pun +1
We study the -ray emission from the pulsar magnetosphere based on outer gap models, and the TeV radiation from pulsar wind nebulae (PWNe) through inverse Compton scattering usin…
A relativistic helical jet in the gamma-ray AGN 1156+295
X. Y. Hong, D. R. Jiang, L. I. Gurvits +7
We present the results of a number of high resolution radio observations of the AGN 1156+295. These include multi-epoch and multi-frequency VLBI, VSOP, MERLIN and VLA observations…
