The first polarimetric signatures of infrared jets in X-ray binaries

Abstract:

We present near-infrared linear spectropolarimetry of a sample of persistent X-ray binaries, Sco X-1, Cyg X-2 and GRS1915+105. The slopes of the spectra are shallower than what is expected from a standard steady-state accretion disc, and can be explained if the near-infrared flux contains a contribution from an optically thin jet. For the neutron star systems, Sco X-1 and Cyg X-2, the polarization levels at 2.4um are 1.3+/-0.10% and 5.4+/-0.7% respectively which is greater than the polarizati...
