Journal ArticleDOI
A deep chandra survey of the globular cluster 47 tucanae: catalog of point sources
Craig O. Heinke,Craig O. Heinke,J. E. Grindlay,P. D. Edmonds,Haldan N. Cohn,Phyllis M. Lugger,Fernando Camilo,Slavko Bogdanov,Paulo C. C. Freire +8 more
TL;DR: In this paper, the authors detect 300 X-ray sources within the half-mass radius (279) of the globular cluster 47 Tucanae in a deep (281 ks) Chandra exposure.
Journal ArticleDOI
Analysis of the Quiescent Low‐Mass X‐Ray Binary Population in Galactic Globular Clusters
Craig O. Heinke,Jonathan E. Grindlay,Phyllis M. Lugger,Haldan N. Cohn,P. D. Edmonds,D. A. Lloyd,Adrienne M. Cool +6 more
TL;DR: In this article, the authors report a complete census of the qLMXB population in these clusters, identifying three additional probable low-mass X-ray binaries in NGC 6440.
Journal ArticleDOI
Improved mass and radius constraints for quiescent neutron stars in ω Cen and NGC 6397
Craig O. Heinke,Haldan N. Cohn,Phyllis M. Lugger,N. A. Webb,Wynn C. G. Ho,Jay Anderson,Sergio Campana,Slavko Bogdanov,Daryl Haggard,Adrienne M. Cool,J. E. Grindlay +10 more
TL;DR: In this article, Chandra and XMM-Newton observations of the globular clusters omega Cen and NGC 6397 were used to measure the spectrum of quiescent neutron stars (NSs), and thus to constrain the allowed ranges of mass and radius for each.
Journal ArticleDOI
Faint X-Ray Sources in the Globular Cluster Terzan 5
Craig O. Heinke,Rudy Wijnands,Haldan N. Cohn,Phyllis M. Lugger,J. E. Grindlay,D. Pooley,Walter H. G. Lewin +6 more
TL;DR: In this article, the authors report the analysis of a Chandra X-ray observation of the rich globular cluster Terzan 5, in which they detect 50 sources to a limiting 1.0-6 keV X ray luminosity of 3 × 1031 ergs s-1 within the half-mass radius of the cluster.
Journal ArticleDOI
Discovery of a second transient low-mass x-ray binary in the globular cluster ngc 6440
