Three Ultraluminous X-ray Sources Hosted by Globular Clusters in NGC 1316
Kristen C. Dage, Arunav Kundu, Erica Thygesen +8
We have identified three ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) within NGC 1316's stellar system. These discoveries bring the total number of known UL…
Discovery of a New Redback Millisecond Pulsar Candidate: 4FGL J0940.3-7610
Samuel J. Swihart, Jay Strader, Elias Aydi +3
We have discovered a new candidate redback millisecond pulsar binary near the center of the error ellipse of the bright unassociated Fermi-LAT -ray source 4FGL J0940.3-7610. The…
A New Candidate Transitional Millisecond Pulsar in the Sub-luminous Disk State: 4FGL J0407.7--5702
Jessie M. Miller, Samuel J. Swihart, Jay Strader +7
We report the discovery of a variable optical and X-ray source within the error ellipse of the previously unassociated Fermi Large Area Telescope -ray source 4FGL J0407.7--5702.…
X-Ray Spectroscopy of Newly Identified ULXs Associated With M87's Globular Cluster Population
Kristen C. Dage, Stephen E. Zepf, Erica Thygesen +5
We have identified seven ultraluminous X-ray sources (ULXs) which are coincident with globular cluster candidates (GCs) associated with M87. ULXs in the old GC environment represen…
A New Likely Redback Millisecond Pulsar Binary with a Massive Neutron Star: 4FGL J2333.1--5527
Samuel J. Swihart, Jay Strader, Ryan Urquhart +7
We present the discovery of a likely new redback millisecond pulsar binary associated with the \emph{Fermi} -ray source 4FGL J2333.1--5527. Using optical photometric and spectro…
Slow Decline and Rise of the Broad [OIII] Emission Line in Globular Cluster Black Hole Candidate RZ2109
Kristen C. Dage, Stephen E. Zepf, Arash Bahramian +6
RZ2109 is the first of several extragalactic globular clusters shown to host an ultraluminous X-ray source. RZ2109 is particularly notable because optical spectroscopy shows it has…
