However, a common scenario which is able to explain the emission from soft to hard X-rays has been proposed only recently. Here, we use XMM and INTEGRAL data on 1E 1740.7−2942 in order to demonstrate that Comptonization plays an important role in producing high energy photons, as predicted by the current modeling scenario.5 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
