A variable ultraluminous X-ray source in a globular cluster in NGC 4649
T. P. Roberts, G. Fabbiano, B. Luo +9
We report the discovery of a new ultraluminous X-ray source (ULX) associated with a globular cluster in the elliptical galaxy NGC 4649. The X-ray source was initially detected with…
Two stellar-mass black holes in the globular cluster M22
Jay Strader, Laura Chomiuk, Thomas Maccarone +2
Hundreds of stellar-mass black holes likely form in a typical globular star cluster, with all but one predicted to be ejected through dynamical interactions. Some observational sup…
No Evidence for Intermediate-Mass Black Holes in Globular Clusters: Strong Constraints from the JVLA
Jay Strader, Laura Chomiuk, Thomas Maccarone +4
With a goal of searching for accreting intermediate-mass black holes (IMBHs), we report the results of ultra-deep Jansky VLA radio continuum observations of the cores of three Gala…
