Chandra Studies of Millisecond Pulsars in Globular Clusters
Jonathan E. Grindlay
The high resolution X-ray imaging and broad-band moderate resolution spectra enabled by the ACIS cameras on the Chandra X-ray Observatory have opened a new window in our study of m…
Three Years of ChaMPlane Northern Field WIYN Spectroscopy
A. B. Rogel, P. M. Lugger, H. N. Cohn +4
We present initial results of WIYN spectroscopic observations of selected objects detected in the Chandra Multiwavelength Plane (ChaMPlane) Survey in fields towards the Galactic an…
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…
The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data
B. J. Wilkes, P. Green, R. Brissenden +34
The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, <0.5" spatial resolution and low background are providing views of…
