My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms. I am particularly interested in the stability properties of accretion discs, the generation of MHD turbulence and associated angular momentum transport, disk - planet interactions and the origin and characteristics of jets and winds from accreting systems . ...

... This is generally not a problem for point sources but for regions of extended emission it can cause an extracted spectrum to be a mix of flux from different areas of an object. It may be possible to disentangle the true sky emission by simultaneously fitting different spectral files. In this case an ARF giving the expected contribution (effective area) of flux received in one area from a different area is needed. ...
