An artist's impression of a relativistic jet propagating away from a black hole at close to the speed of light. Such jets are formed by the inner regions of the accretion flow: matter flowing inwards towards the black hole, via processes which are not yet fully understood. The accretion flow emits primarily in X-rays, the relativistic jet in the radio band: by combing observations in each band we can try and understand how such jets form and how much energy they carry away from the black hole.

Abstract:

We present JHK photometry and spectroscopy of RX J0019.8+2156. The spectrum appears to be dominated by the accretion disc to at least 2.4 μm, over any other source of emission. We find Paschen, Brackett and He II lines strongly in emission, but no He I. There are satellite lines approximately 850km s-1 either side of the strongest, unblended hydrogen lines. These satellite lines may be the spectral signature of jets from the accretion disc.
