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
On the possibilities of high-energy neutrino production in the jets of microquasar SS433 in light of new observational data
Abstract Microquasar SS433 is composed by a supergiant star that feeds mass through a supercritical accretion disk to a  ∼10 M⊙ black hole. The latter launches two oppositely directed jets that
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 .
Neutrino production in Population III microquasars
Microquasars (MQs) are binary systems composed by a star feeding mass to a compact object through an accretion disk. The compact object, usually a black hole, launches oppositely directed jets which
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
SS433: A massive X-ray binary in an advanced evolutionary stage
Abstract INTEGRAL IBIS/ISGRI 18–60 keV observations of SS433 performed in 2003–2011 enabled for the first time the hard X-ray phase-resolved orbital and precessional light curves and spectra to be
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 up to the upturn commonly called the ankle, from around the spectral turn-down commonly called the knee, mostly come from Blue Supergiant star
Tentative evidence of spatially extended GeV emission from SS433/W50
We have analyzed ten years of the Fermi Large Area Telescope data toward the SS433/W50 region. With the latest source catalog and diffuse background models, the γ-ray excess from SS433/W50 is


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
VERITAS Observations of High-Mass X-Ray Binary SS 433
Despite decades of observations across all wavebands and dedicated theoretical modelling, the SS 433 system still poses many questions, especially in the high-energy range. SS 433 is a high-mass
A simple formalism to describe nonthermal electron acceleration, evolution, and radiation in supernova remnants (SNRs) is presented. The electron continuity equation is analytically solved assuming
XMM-Newton observations of the eastern jet of SS 433
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
Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE) gamma-ray emitter. Gamma-ray fluxes have been
Detection of persistent gamma-ray emission toward SS433/W50
The microquasar SS433 features the most energetic jets known in our Galaxy. A large fraction of the jet kinetic power is delivered to the surrounding W50 nebula at the jet termination shock, from
