The formation mechanism of the W50/SS 433 complex has long been a mystery. We propose a new scenario in which the SS 433 jets themselves form the W50/SS 433 system. We carry out magnetohydrodynamics simulations of the propagation of two side jets using the public code CANS+. As found in previous jet studies, when the propagating jet is lighter than the surrounding medium, the shocked plasma flows back from the jet tip to the core. We find that the morphology of light jets is spheroidal at early… 
Energy estimation of high-energy particles associated with the SS 433/W 50 system through radio observation at 1.4 GHz
The radio nebula W 50 is a unique object interacting with the jets of the microquasar SS 433. The SS 433/W 50 system is a good target for investigating the energy of cosmic-ray particles


A High-Resolution Radio Study of the W50-SS 433 System and the Surrounding Medium
We present VLA images at 327.5 and 1465 MHz of the nebula W50 surrounding the stellar source of relativistic jets SS 433. At 1.4 GHz, we have produced an image of W50 with an angular resolution of
Probing the history of SS 433’s jet kinematics via decade-resolution radio observations of W 50
We present the results of a kinematical study of the W 50 nebula using high-resolution radio observations from the Very Large Array spanning a 12-yr period, sampled in 1984, 1993 and 1996. We conduct
When microquasar jets and supernova collide: hydrodynamically simulating the SS 433–W 50 interaction
We present investigations of the interaction between the relativistic, precessing jets of the microquasar SS433 and the surrounding, expanding supernova remnant (SNR) shell, W50, and the consequent
ROSAT and ASCA Observations of W50 Associated with the Peculiar Source SS 433
We report the observations of the X-ray lobes of the large Galactic source W50 associated with the two-sided jets source SS 433. The observations were made with the Position Sensitive Proportional
The SS433 jet from subparsec to parsec scales
Context. Relativistic jets associated with compact objects, as in the X-ray binary SS433, are known to be multiscale because they spawn over many orders of magnitude in distance. Here we model the
A Sino-German λ6 cm polarization survey of the Galactic plane - V. Large supernova remnants
Context. Observations of large supernova remnants (SNRs) at high frequencies are rare, but provide valuable information about their physical properties. Aims. The total intensity and polarization
The Distance to SS433/W50 and its Interaction with the ISM
[ABRIDGED] The distance to the relativistic jet source SS433 and the related supernova remnant W50 is re-examined using new observations of HI in absorption from the VLA, HI in emission from the GBT,
