MAXI J1848-015: The First Detection of Relativistically Moving Outflows from a Globular Cluster X-Ray Binary

Over the past decade, observations of relativistic outflows from outbursting X-ray binaries in Galactic field have grown significantly. In this work, we present first detection moving and decelerating radio-emitting an binary a globular cluster. MAXI J1848-015 is recently discovered transient direction cluster GLIMPSE-C01. Using VLA, monitoring campaign with MeerKAT observatory for 500 days, model motion outflows. This represents some most intensive, long-term coverage relativistically to date. We use proper motions constrain component intrinsic jet speed along line sight, $\beta_\textrm{int} \cos \theta_\textrm{ejection}$, be $=0.19\pm0.02$. Assuming it located GLIMPSE-C01, at 3.4 kpc, determine speed, $\beta_\textrm{int}=0.79\pm0.07$, inclination angle $\theta_\textrm{ejection}=76^\circ\pm2^{\circ}$. makes somewhat slower than those seen many other known binaries. also maximum distance $4.3$ kpc. Lastly, discuss implications our findings nature compact object system, finding that black hole primary viable (but as-of-yet unconfirmed) explanation observed properties J1848-015. If future data and/or analysis provide more conclusive evidence indeed hosts hole, would outburst identified
