Emerging pictures on the disk-jet connection from simultaneous multiwavelength observations of black hole X-ray binaries
Abstract
Relativistic jets in black hole X-ray binaries (BHXBs) are fundamentally linked to accretion onto the central black hole. Since the outbursts of X-ray binaries, stellar mass cousins of AGN, typically last weeks to months, BHXBs are ideal targets for probing the connected physics of accretion disks and jets over entire outbursts. However, this fast evolution requires coordinated multiwavelength monitoring observations to best probe this physics. The relativistic jet is typically best probed at low frequencies (radio, mm/sub-mm, mid-IR, near-IR, optical) with ground-based observatories while the accretion disk is best probed at X-ray frequencies from space-based observatories. Over the last several years stronger coordination among scientific teams and these facilities has enabled a greater number of near-simultaneous or simultaneous observations. In this talk, I use examples from a range of campaigns (e.g., MAXI J1836-194 & V404 Cyg) to discuss the gains that are being made with increasingly simultaneous observations. I highlight how four specific multi-wavelength trends (flux monitoring with high resolution imaging; dynamic nearly simultaneous SEDs; the push to mm/sub-mm frequencies; comparison of high time resolution data) are producing data that are increasingly testing theoretical models of jet production.
