ROSAT Wide Field Camera Data and the Temperature of the Interstellar Medium
Abstract
The shadowing effects of the molecular clouds in the nearby interstellar medium on the soft x-ray background has been investigated, using ROSAT WFC data in conjunction with previous rocket B and C band surveys. Shadowing over a 5° extent occurs only for a few percent of the sky, but the mixed model of the ISM is supported. Detailed modelling of the ‘Draco’ shadowing region shows little evidence for a multi-temperature, hot ISM component.
