A Deep Search for Faint Chandra X-ray Sources, Radio Sources, and Optical Counterparts in NGC 6752
Haldan N. Cohn, Phyllis M. Lugger, Yue Zhao +6
We report the results of a deep search for faint Chandra X-ray sources, radio sources, and optical counterparts in the nearby, core-collapsed globular cluster, NGC 6752. We combine…
A deep Chandra survey for faint X-ray sources in the Galactic globular cluster M30, and searches for optical and radio counterparts
Yue Zhao, Craig O. Heinke, Haldan N. Cohn +11
We present a deep () {\it Chandra} survey of the Galactic globular cluster M30 (NGC 7099). Combining the new Cycle 18 with the previous Cycle 3 observations w…
Identification of Faint Chandra X-ray Sources in the Core-Collapsed Globular Cluster NGC 6752
Phyllis M. Lugger, Haldan N. Cohn, Adrienne M. Cool +2
We have searched for optical identifications for 39 Chandra X-ray sources that lie within the 1.9 arcmin half-mass radius of the nearby (d = 4.0 kpc), core-collapsed globular clust…
Discovery of near-ultraviolet counterparts to millisecond pulsars in the globular cluster 47 Tucanae
L. E. Rivera-Sandoval, M. van den Berg, C. O. Heinke +11
We report the discovery of the likely white dwarf companions to radio millisecond pulsars 47 Tuc Q and 47 Tuc S in the globular cluster 47 Tucanae. These blue stars were found in n…
A Deep Chandra X-ray Limit on the Putative IMBH in Omega Centauri
Daryl Haggard, Adrienne M. Cool, Craig O. Heinke +4
We report a sensitive X-ray search for the proposed intermediate mass black hole (IMBH) in the massive Galactic cluster, Omega Centauri (NGC 5139). Combining Chandra X-ray Observat…
Fokker-Planck Models for M15 without a Central Black Hole: The Role of the Mass Function
Brian W. Murphy, Haldan N. Cohn, Phyllis M. Lugger
We have developed a set of dynamically evolving Fokker-Planck models for the collapsed-core globular star cluster M15, which directly address the issue of whether a central black h…
