SAX J1808.4-3657 in Quiescence: A Keystone for Neutron Star Science
C. O. Heinke, C. J. Deloye, P. G. Jonker +2
The accreting millisecond pulsar SAX J1808.4-3658 may be a transition object between accreting X-ray binaries and millisecond radio pulsars. We have constrained the thermal radiati…
Flaring Activity of Sgr A*: Expanding Hot Blobs
F. Yusef-Zadeh, M. Wardle, D. A. Roberts +5
Sgr A* is considered to be a massive black hole at the Galactic center and is known to be variable in radio, millimeter, near-IR and X-rays. Recent multi-wavelength observing campa…
X-ray and Optical Studies of Millisecond Pulsars in 47 Tucanae
C. O. Heinke, J. E. Grindlay, P. D. Edmonds +1
Our Chandra X-ray observation of the globular cluster 47 Tuc clearly detected most of the 16 MSPs with precise radio positions, and indicates probable X-ray emission from the remai…
Chandra on Millisecond Pulsars in Globular Clusters
J. E. Grindlay, C. O. Heinke, P. D. Edmonds +1
We summarize the x-ray properties of the complete samples of millisecond pulsars (MSPs) detected in our Chandra observations of the globular clusters 47 Tuc and NGC 6397. The 47 Tu…
Variability and Spectra of Two Neutron Stars in 47 Tucanae
C. O. Heinke, J. E. Grindlay, D. A. Lloyd +1
We report spectral and variability analysis of two quiescent low mass x-ray binaries (previously identified with ROSAT HRI as X5 and X7) in the globular cluster 47 Tuc, from a Chan…
