Radio emission and jets from microquasars
E. Gallo (MIT, Usa)

TL;DR
Microquasars are Galactic binary systems with compact objects that produce jets, offering insights into jet physics and accretion processes on observable short time-scales, with implications for understanding cosmic structure evolution.
Contribution
This chapter discusses the conditions for microquasar formation, their jet phenomena, and their significance in studying accretion and jet physics through rapid variability.
Findings
Jets contribute significantly to energy dissipation.
Microquasars exhibit fast variability enabling detailed study.
Jet-accretion coupling depends on the mass of the compact object.
Abstract
To some extent, all Galactic binary systems hosting a compact object are potential `microquasars', so much as all galactic nuclei may have been quasars, once upon a time. The necessary ingredients for a compact object of stellar mass to qualify as a microquasar seem to be: accretion, rotation and magnetic field. The presence of a black hole may help, but is not strictly required, since neutron star X-ray binaries and dwarf novae can be powerful jet sources as well. The above issues are broadly discussed throughout this Chapter, with a a rather trivial question in mind: why do we care? In other words: are jets a negligible phenomenon in terms of accretion power, or do they contribute significantly to dissipating gravitational potential energy? How do they influence their surroundings? The latter point is especially relevant in a broader context, as there is mounting evidence that…
