Relativistic outflows from galactic sources
- Marc Ribó (Universitat de Barcelona / ICCUB / IEEC-UB)
Relativistic jets are ubiquitous phenomena present in a variety of galactic sources. These jets can carry a significant fraction of the system's energy reservoir up to distances of a few tens of parsecs. Particle acceleration along the jets or at the interaction sites with the surrounding medium leads to the production of copious non-thermal emission, which is observed in a broad energy range,...
The large-scale morphology of the prototypical microquasar GRS 1758-258 resembles the Z-shape of the subclass of extragalactic radio sources known as winged radio galaxies. This new quasar-microquasar analogy allows us to study the nature of the origin of this peculiar morphology, which seems to be related to the hydrodynamical back flow. Some other implications could be stated assuming that...
Compact, continuously launched jets in black hole X-ray binaries (BHXBs) produce radio to optical–infrared (OIR) synchrotron emission. These jets are launched in the hard X-ray state, and are quenched in the soft state. They are not spatially resolved except in a few cases using VLBI radio observations. One of the basic properties of these jets is the bulk Lorentz factor, which defines how...
It is widely accepted that the power-law X-ray spectra of black-hole X-ray binaries (BHXRBs) are produced by inverse Compton scattering in a corona, which is typically taken to be the hot inner flow around the black hole or the base of the jet. However, if a photon finds itself in the hot inner flow or the base of the jet, nothing prevents it from traveling higher up in the body of the jet. ...
