“…However, up to now there is no robust evidence for this object of interaction between its relativistic ejecta and the surrounding ISM on larger, few pc scales. This is in contrast with other microquasars, such as Cygnus X-1 or Circinus X-1, where a clear signature of interaction is detected between their relativistic jets and the ISM (Gallo et al 2005, Tudose et al 2007b). …”

We present a new search for possible extended radio features in the Cygnus X-3 environment as a result of the persistent flaring history of this microquasar. We focus our attention here on few arc-minute angular scales, i.e., closer than previously explored. This work is mostly based on the analysis of VLA archive data, including the CGPS and GB6 surveys. We also use deep near infrared observations obtained by ourselves in 2005.Our main result is a new radio map of Cygnus X-3 obtained after combining multi-configuration VLA archive data at 6 cm. This is probably the deepest radio image of this microquasar reported up to date at cm wavelengths (rms noise 9.5 µJy/beam). It reveals a curious plume of extended radio emission, just within a few arc-minute from the microquasar position, with a morphology reminiscent of some radiogalaxies like 3C 264 and possibly non-thermal. Its physical connection with the microquasar is tentatively considered. We also report on the serendipitous discovery of a Fanaroff-Riley type II radio galaxy very close in the sky to Cygnus X-3. This provides a curious 'family picture' of two accreting sources in the same shot. From Planets to Dark Energy: the Modern Radio Universe

“…This gives a B-strength of about ∼4-6 × 10 −5 G depending on t src . These B-values are one order of magnitude higher than those inferred by Tudose et al (2006) and Safi-Harb & Petre (1999) for the jet termination regions in Circinus X-1 (a low-mass microquasar) and SS 433, respectively. On the other hand, the ages of these sources are also about one order of magnitude older than those considered here, and thus a lower magnetic field is naturally expected in the former cases.…”

Context. The environment of high-mass X-ray binaries can be characterized either by the supernova remnant that forms these systems or by the wind from the companion massive star. These regions should be tenuous but very hot and surrounded by a dense and cold shocked ISM shell. The interaction between the jet and such a complex medium, also affected by the system proper motion, can lead to very different jet termination structures. Aims. The evolution of the jet termination regions during the life of a high-mass microquasar is simulated to improve our present understanding of these structures. Also, the evolving emission characteristics are modeled to inform potential observational campaigns of this class of object. Methods. We performed 2D numerical simulations of jets propagating in different scenarios, corresponding to different epochs after the formation of the high-mass X-ray binary, using the code Ratpenat. We also made simple estimates of the nonthermal emission that could be produced in the jet termination regions. Results. We find that, in the way through the hot and tenuous medium of the shocked wind/supernova ejecta, the jet suffers recollimation shocks in which it loses part of its thrust and ends in a strong shock inflating a hot cocoon. The jet head propagates with a speed that is similar to the medium sound speed, until it eventually reaches the denser and colder shocked ISM and the unperturbed ISM later on. In these last stages of evolution, the jet is significantly slowed down and can be disrupted. For relatively old sources, the microquasar peculiar velocity becomes important, leading to complete jet destruction. Extended nonthermal radiation can be generated in the jet termination regions, and hard X-rays and TeV photons are the wavelengths best suited for observing these structures.

“…In the case of MQs, evidence of jet interaction with the interstellar medium (ISM) are not numerous, partially due to the relatively small number of known sources. Nevertheless, hints or evidence of these interactions have been observed, at different wavelengths, in SS 433 (Zealey et al 1980), 1E 1740.7−2942 (Mirabel et al 1992), XTE J1550−564 (Corbel et al 2002), Cygnus X-3 (Heindl et al 2003), Cygnus X-1 (Martí et al 1996;Gallo et al 2005), GRS 1915+105 (Kaiser et al 2004), H1743−322 (Corbel et al 2005), LS I +61 303 (Paredes et al 2007a), and Circinus X-1 (Tudose et al 2006), although little theoretical work has been completed regarding the hydrodynamics of the interaction, or the resulting non-thermal emission (e.g. Aharonian & Atoyan 1998;Velázquez & Raga 2000;Heinz & Sunyaev 2002;Bosch-Ramon et al 2005;Perucho & Bosch-Ramon 2008).…”

Context. The interaction of microquasar jets with their environment can produce non-thermal radiation as in the case of extragalactic outflows impacting on their surroundings. Significant observational evidence of jet/medium interaction in galactic microquasars has been collected in the past few years, although little theoretical work has been done regarding the resulting non-thermal emission. Aims. In this work, we investigate the non-thermal emission produced in the interaction between microquasar jets and their environment, and the physical conditions for its production. Methods. We developed an analytical model based on those successfully applied to extragalactic sources. The jet is taken to be a supersonic and mildly relativistic hydrodynamical outflow. We focus on the jet/shocked medium structure in its adiabatic phase, and assume that it grows in a self-similar way. We calculate the fluxes and spectra of the radiation produced via synchrotron, inverse Compton, and relativistic bremsstrahlung processes by electrons accelerated in strong shocks. A hydrodynamical simulation is also performed to investigate further the jet interaction with the environment and check the physical parameters used in the analytical model. Results. For reasonable values of the magnetic field, and using typical values of the external matter density, the non-thermal particles could produce significant amounts of radiation at different wavelengths, although they do not cool primarily radiatively, but by adiabatic losses. The physical conditions of the analytical jet/medium interaction model are consistent with those found in the hydrodynamical simulation. Conclusions. Microquasar jet termination regions could be detectable at radio wavelengths for current instruments sensitive to ∼arcminute scales. At X-ray energies, the expected luminosities are moderate, although the emitter is more compact than the radio one. The source may be detectable by XMM-Newton or Chandra, with 1-10 arcsec of angular resolution. The radiation at gamma-ray energies may be within the detection limits of the next generation of satellite and ground-based instruments.
