The evolving jet in the new black hole X-ray binary MAXI J1535-571
Abstract
MAXI J1535-571 is a recently discovered and very bright Galactic black hole X-ray binary. Here, I will present results from our comprehensive ATCA radio and ALMA millimetre monitoring of this source throughout its outburst. Our multi-frequency coverage show the observed jet spectrum changing rapidly as the source transitioned from the hard state towards the soft state, indicating dramatic changes in the jet over relatively short timescales. Surprisingly, we detect core radio emission throughout the soft state, placing limits on the level of jet quenching in this source. I will also discuss the monitoring of two downstream radio knots/shocks, allowing us to place constraints on their speed and time of their ejection, which can then be linked back to changes in X-ray properties. These radio and millimeter observations provide an unprecedented insight into the changing jet structure, and how the accretion flow may be driving those changes.
