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…
A Search for Periodicities in the B Solar Neutrino Flux Measured by the Sudbury Neutrino Observatory
SNO Collaboration
A search has been made for sinusoidal periodic variations in the B solar neutrino flux using data collected by the Sudbury Neutrino Observatory over a 4-year time interval. The…
Limits from the Hubble Space Telescope on a Point Source in SN 1987A
G. J. M. Graves, P. M. Challis, R. A. Chevalier +16
We observed supernova 1987A (SN 1987A) with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST) in 1999 September, and again with the Advanced Camer…
Early Re-brightenings in GRB Afterglows as Signatures of Low-to-High Density Boundary
P. H. Tam, C. S. J. Pun, Y. F. Huang +1
The association of long gamma-ray bursts (GRBs) with star forming regions and the idea of massive stars as progenitors of GRBs are widely accepted. Because of their short lifetimes…
