The X-ray binary SS 433, embedded in the W 50 nebula (or supernova remnant W 50), shows bipolar jets that are ejected with mildly relativistic velocities and which extend toward the east and west out to scales of tens of parsecs. Previous X-ray observations revealed twin lobes along the jet precession axis that contain compact bright knots dominated by synchrotron radiation, which provide evidence of electron acceleration in this system. Particle acceleration in this system is substantiated… 



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

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

Rossi X-Ray Timing Explorer Observations of the Eastern Lobe of W50 Associated with SS 433

We present the Rossi X-Ray Timing Explorer (RXTE) observations of the SNR W50, associated with SS 433. The observations cover the X-ray lobe found between SS 433 and the outer eastern radio "ear" of

GeV–TeV Counterparts of SS 433/W50 from Fermi-LAT and HAWC Observations

The extended jets of the microquasar SS 433 have been observed in optical, radio, X-ray, and recently very-high-energy γ-rays by High Altitude Water Cerenkov (HAWC). The detection of HAWC γ-rays with

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

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

Very-high-energy particle acceleration powered by the jets of the microquasar SS 433

Teraelectronvolt γ-ray observations of the SS 433/W50 system that spatially resolve the lobes conclude that the emission—from radio to teraelectronsvolt energies—is consistent with a single population of electrons with energies extending to at least hundreds of teraelectedronvolts in a magnetic field of about 16 microgauss.

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

A Small-scale Investigation of Molecular Emission toward the Tip of the Western Lobe of W50/SS 433

We perform a molecular (CO and CN) line observation using the IRAM 30 m telescope toward two small regions near the western edge of supernova remnant (SNR) W50/SS 433. CO observation reveals spatial

An X-Ray Face-On View of the Sagittarius B Molecular Clouds Observed with Suzaku

We present a new methodology to derive the positions of the Sgr B molecular clouds (MCs) along the line of sight, as an application study of the Galactic center diffuse X-rays (GCDX). The GCDX is
