Review of the Solar Array Telescopes
David A. Smith
For several years the only experiments sensitive to astrophysical gamma rays with energies beyond the reach of EGRET but below that of the Cherenkov imaging telescopes have been th…
Confronting the Superbubble Model with X-ray Observations of 30 Dor C
David A. Smith, Q. Daniel Wang
We present an analysis of XMM-Newton observations of the superbubble 30 Dor C and compare the results with the predictions from the standard wind-blown bubble model. We find that t…
A Chandra X-ray Study of NGC 1068: II. The Luminous X-ray Source Population
David A. Smith, Andrew S. Wilson
We present an analysis of the compact X-ray source population in the Seyfert~2 galaxy NGC 1068, imaged with Chandra. We find a total of 84 compact sources, of which 66 are projecte…
On the influence of radio galaxies on cooling flows: M87 and Cygnus A
Andrew S. Wilson, Andrew J. Young, David A. Smith
Results from Chandra studies of the intracluster medium around M87 and Cygnus A are summarized.
Monitoring RXTE Observations of Markarian 348: the origin of the column density variations
A. Akylas, I. Georgantopoulos, R. G. Griffiths +5
We analyze 37 RXTE observations of the type 2 Seyfert galaxy Mrk348 obtained during a period of 14 months. We confirm the spectral variability previous reported by Smith et al., in…
The X-ray Spectrum of Cyg X-2
C. Done, P. T. Zycki, D. A. Smith
The spectra of disc accreting neutron stars generally show complex curvature, and individual components from the disc, boundary layer and neutron star surface cannot be uniquely id…
