SS 433 is a binary system containing a supergiant star that is overflowing its Roche lobe with matter accreting onto a compact object (either a black hole or neutron star)1–3. Two jets of ionized matter with a bulk velocity of approximately 0.26c (where c is the speed of light in vacuum) extend from the binary, perpendicular to the line of sight, and terminate inside W50, a supernova remnant that is being distorted by the jets2,4–8. SS 433 differs from other microquasars (small-scale versions… 
Discovery of the TeV Emission from the Jet Interaction Regions of SS 433 with HAWC
The High Altitude Water Cherenkov (HAWC) observatory recently published the discovery of SS 433 as a TeV source, reporting the observation of multi-TeV gamma-ray emission from the jet interaction
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
Gamma-ray heartbeat powered by the microquasar SS 433
Microquasars, the local siblings of extragalactic quasars, are binary systems comprising a compact object and a companion star. By accreting matter from their companions, microquasars launch powerful
Multiwavelength Emission from Galactic Jets: The Case of the Microquasar SS433
SS433 is a Galactic microquasar with powerful jets, where very-high-energy particles are produced. We study particle acceleration in the jets of SS433 in the light of the recent multi-wavelength data
Diffuse X-ray emission around an ultraluminous X-ray pulsar
Ultraluminous X-ray sources (ULXs) are extragalactic X-ray emitters located off-centre of their host galaxy and with a luminosity in excess of a few 10 39  erg s −1 , if emitted isotropically 1 , 2 .
Particle acceleration in radio galaxies with flickering jets: GeV electrons to ultrahigh energy cosmic rays
Variability is a general property of accretion discs and their associated jets. We introduce a semi-analytic model for particle acceleration and radio jet/lobe evolution and explore the effect of Myr
The Origin of the Most Energetic Galactic Cosmic Rays : Supernova Explosions into Massive Star Plasma Winds
We propose that the high energy Cosmic Ray particles around the spectral turn-down commonly called the knee and up to the upturn, commonly called the ankle, mostly come from Blue Super Giant star

Sources of Relativistic Jets in the Galaxy
▪ Abstract Black holes of stellar mass and neutron stars in binary systems are first detected as hard X-ray sources using high-energy space telescopes. Relativistic jets in some of these compact
Relativistic Jets in Active Galactic Nuclei and Microquasars
Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the accretion of material onto a compact object. Despite this ubiquity, many fundamental physics aspects of jets are
Jets of SS 433 on scales of dozens of parsecs
The radio nebula W50 harbours the relativistic binary system SS433, which is a source of the powerful wind and jets. The origin of W50 is wrapped in the interplay of the wind, supernova remnant and

Context. The radio supernova remnant W50 hosts at its center the peculiar galactic X-ray binary SS 433. It shows a central spherical structure with two “ears” which are supposed to be formed by the
Production of gamma rays and neutrinos in the dark jets of the microquasar SS433
We study the spectral energy distribution of gamma rays and neutrinos in the precessing microquasar SS433 as a result of pp interactions within its dark jets. Gamma-ray absorption due to interactions
The nature of SS433 and the ultraluminous X-ray sources
The periodic precession (162-d) and nodding (6.3-d) motions of the jets in SS433 are driven in the outer regions of the disc, whereas the jets themselves, being relativistic, are launched near the
