Presentation #110.71 in the session “Stellar/Compact (Poster)”.
The Zwicky Transient Facility (ZTF) detects hundreds of thousands of variable, transient, and moving sources per night. These sources are packaged into alerts and publicly released via a Kafka stream. We created a pipeline to search this stream for outbursting X-ray binaries (XRBs) by crossmatching the positions of the alerts to catalogued X-ray sources, and then analyzing the 30 day lightcurve of matched alerts by thresholding on differences with an 8-day exponentially weighted moving average. In addition to the year-long live search for XRBs, we ran the pipeline over three years of ZTF archival data. We discuss the implication for the rate of optically-detectable XRB outbursts in the galaxy.
