A new likely pulsar binary in 47~Tucanae from continuum searches
Thomas J. Maccarone, Alessandro Paduano, Arash Bahramian +6
We present evidence that the X-ray source 47~Tuc~W41, long considered to be an X-ray source powered by coronal activity, is actually a redback pulsar binary. The source continually…
New Deep Radio Continuum Imaging Still Indicates a Large Reservoir of Undiscovered Millisecond Pulsars in Terzan 5
Ryan Urquhart, Jay Strader, Laura Chomiuk +4
We present the deepest and highest-resolution radio continuum imaging of the Galactic globular cluster Terzan 5, one of the most crowded locations in the radio sky. In these new 2$…
What determines the -ray luminosities of classical novae?
Peter Craig, Elias Aydi, Laura Chomiuk +25
Classical novae in the Milky Way have now been well-established as high-energy GeV -ray sources. In novae with main-sequence companions, this emission is believed to result fro…
No evidence for accretion around the intermediate-mass black hole in Omega Centauri
Angiraben D. Mahida, Arash Bahramian, James C. A. Miller Jones +5
For over a decade, both theoretical predictions and observational studies have suggested that Centauri ( Cen), the most massive Milky Way globular cluster, might harbor an…
The X-ray Source Population of the Metal-Rich Globular Cluster NGC 6528
Bernard Leal, Kwangmin Oh, Jay Strader +4
We present the first study of the X-ray sources in one of the most metal-rich globular clusters in the Galaxy, NGC 6528. Using relatively deep (66 ksec) archival imaging from the C…
Spectral Insights and Evolutionary Pathways of Globular Cluster ULX in NGC 1399: A Two-Decade X-ray and Optical Study
Kwangmin Oh, Kristen C. Dage, Alexey Bobrick +9
We present new multi-wavelength observations of two ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) in the giant elliptical NGC 1399, focusing on CXO J0338318-…
