A pulsar escaping an ancient open cluster via tidal stripping
Lei Zhang, Xiaoting Fu, Di Li +21
Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…
A Comprehensive Analysis of X-ray Sources in Terzan 5 Using Chandra Observations
Gourav Kumawat, Craig O. Heinke, Jiaqi Zhao +3
We analyze photometry, spectra, and variability of over 100 faint X-ray sources in the globular cluster Terzan 5, using 737 ks of Chandra data. X-ray colors and spectral fitting al…
A deep Chandra study verifies diffuse non-thermal X-ray emission from the globular cluster Terzan 5
Jiaqi Zhao, Craig O. Heinke, Su Fu
Diffuse X-ray emission has been detected from a few Galactic globular clusters (GCs), whereas its nature still remains largely unclear. The GC Terzan 5 was previously found to show…
Exploration of faint X-ray and radio sources in the massive globular cluster M14: A UV-bright counterpart to Nova Ophiuchus 1938
Yue Zhao, Francesca D'Antona, Antonino P. Milone +4
Using a 12 ks archival Chandra X-ray Observatory ACIS-S observation on the massive globular cluster (GC) M14, we detect a total of 7 faint X-ray sources within its half-light radiu…
Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 (NGC 5904) with FAST and Arecibo
Lei Zhang, Paulo C. C. Freire, Alessandro Ridolfi +29
We report on a comprehensive multi-wavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact non-eclipsing "black widow" pulsar…
A Chandra X-ray study of millisecond pulsars in the globular cluster Omega Centauri: a correlation between spider pulsar companion mass and X-ray luminosity
Jiaqi Zhao, Craig O. Heinke
Millisecond pulsars (MSPs) are faint X-ray sources commonly observed in Galactic globular clusters (GCs). In this work, we investigate 18 MSPs newly found in the GC Omega Centauri…
Exotica in the Globular Cluster M4, Studied with Chandra, HST, and the VLA
Phyllis M. Lugger, Haldan N. Cohn, Craig O. Heinke +3
Using the Hubble Ultraviolet Globular Cluster Survey (HUGS) and additional HST archival data, we have carried out a search for optical counterparts to the low-luminosity Chandra X-…
A Census of X-ray Millisecond Pulsars in Globular Clusters
Jiaqi Zhao, Craig O. Heinke
We present a comprehensive census of X-ray millisecond pulsars (MSPs) in 29 Galactic globular clusters (GCs), including 68 MSPs with confirmed X-ray luminosities and 107 MSPs with…
Chandra and HST Studies of Six Millisecond Pulsars in the Globular Cluster M13
Jiaqi Zhao, Yue Zhao, Craig O. Heinke
We analyse 55 ks of Chandra X-ray observations of the Galactic globular cluster M13. Using the latest radio timing positions of six known millisecond pulsars (MSPs) in M13 from Wan…
