Mid-Infrared observations of GRS 1915+105 and SS433

We have observed in the mid-infrared (4–18 μm) the counterpart of the compact object GRS 1915+105, and the western jet of SS433. The images were carried out with the ISOCAM infraredcamera on board of the Infrared Space Observatory (ISO). The mid-infrared photometry of GRS 1915+105 shows the presence of an additional contribution besides the synchrotron emission.The 15 μm images of the large-scale western lobe of the SS433/W50 nebula are compared to the radio and X-ray ones. They show infrared synchrotron emission on the western edge of SS433/W50 lobe.
