A rapid change in X-ray variability and a jet ejection in the black hole transient MAXI J1820+070
We present Neutron Star Interior Composition ExplorerX-ray and Arcminute Microkelvin ImagerLarge Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transientMAXI J1820+070. During the transition from the hard state to the soft state a switch between twoparticular types of quasiperiodic oscillations (QPOs) was seen in the X-ray power density spectra, fromtype-C to type-B, along with a drop in the strength of the broadband X-ray variability and a briefflare in the 7–12 keV band. Soon after this switch (∼1.5–2.5 hr) a strong radio flare was observedthat corresponded to the launch of superluminal ejecta. Although hints of a connection betweenQPO transitions and radio flares have been seen in other black hole X-ray transients, our observationsconstitute the strongest observational evidence to date for a link between the appearance of type-BQPOs and the launch of discrete jet ejections.

Abstract
We present Neutron Star Interior Composition ExplorerX-ray and Arcminute Microkelvin ImagerLarge Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transientMAXI J1820+070. During the transition from the hard state to the soft state a switch between twoparticular types of quasiperiodic oscillations (QPOs) was seen in the X-ray power density spectra, fromtype-C to type-B, along with a drop in the strength of the broadband X-ray variability and a briefflare in the 7–12 keV band. Soon after this switch (∼1.5–2.5 hr) a strong radio flare was observedthat corresponded to the launch of superluminal ejecta. Although hints of a connection betweenQPO transitions and radio flares have been seen in other black hole X-ray transients, our observationsconstitute the strongest observational evidence to date for a link between the appearance of type-BQPOs and the launch of discrete jet ejections.
