A Chandra Survey of Milky Way Globular Clusters -- IV. Periodic X-ray sources
Tong Bao, Zhiyuan Li, Zhongqun Cheng +1
We present a systematic search for periodic X-ray sources in 10 Galactic globular clusters (GCs) utilizing deep archival Chandra observations. By applying the Gregory-Loredo algori…
Discovery of Galaxy Clusters and a Head-Tail Radio Galaxy in the Direction of Globular Cluster NGC 6752
Zhongqun Cheng, Xiaohui Sun, Wei Wang +1
We report the discovery of CXOU J191100-595621 and CXOU J191012-595619, two galaxy clusters serendipitously detected in the direction of globular cluster NGC 6752, based on archiva…
Exploring the Mass Segregation Effect of X-ray Sources in Globular Clusters. IV. Evidence of Black Hole Burning in Centauri
Zhongqun Cheng, Zhiyuan Li, Wei Wang +2
Using X-ray sources as sensitive probes of stellar dynamical interactions in globular clusters (GCs), we study the mass segregation and binary burning processes in Cen. We show…
Testing Comptonization as the origin of the continuum in nonmagnetic Cataclysmic Variables. The photon index of X-ray emission
T. Maiolino, L. Titarchuk, F. D'Amico +4
X-ray spectra of nonmagnetic cataclysmic variables (nmCVs) in the ~ 0.315 keV energy band have been described either by one or several optically thin thermal plasma components,…
Exploring the Mass Segregation Effect of X-ray Sources in Globular Clusters. III. Signs of Binary Disruption in M28
Zhongqun Cheng, Huijun Mu, Zhiyuan Li +3
Using archival {\it Chandra} observations with a total effective exposure of 323 ks, we derive an updated catalog of point sources in the bulge globular cluster M28. The catalog co…
Exploring the Mass Segregation Effect of X-ray Sources in Globular Clusters. II. The Case of Terzan 5
Zhongqun Cheng, Zhiyuan Li, Taotao Fang +2
Using archival {\it Chandra} observations with a total effective exposure of 734 ks, we derive an updated catalog of point sources in the massive globular cluster Terzan 5. Our cat…
