Relativistic Fe line emission and highly photoionized absorption in GRO J1655-40

Díaz Trigo, M.; Miller, J. M.; Kuulkers, E. +1 more

We report on two XMM-Newton and simultaneous INTEGRAL observations of the microquasar GRO J1655-40 during its 2005 outburst. The source was most probably in its high-soft state during both observations. There is evidence for the presence of both a relativistically broadened Fe line providing strong support for the existence of a spinning black hol…
