Open AccessImaging Plasma Density Structures in the Soft X-Rays Generated by Solar Wind Charge Exchange with Neutrals
Both heliophysics and planetary physics seek to understand the complex nature of the solar wind’s interaction with solar system obstacles like Earth’s magnetosphere, the ionospheres of Venus and Mars, and come...

The origin of the local 1/4-keV X-ray flux in both charge exchange and a hot bubble
The contribution of solar-wind ions exchanging electrons with helium and hydrogen near the Sun is shown to be only about 40 per cent of the 1/4-keV X-ray flux observed in the Galactic plane; this supports the ...

What Can Be Learned from X-ray Spectroscopy Concerning Hot Gas in the Local Bubble and Charge Exchange Processes?
Both solar wind charge exchange emission and diffuse thermal emission from the Local Bubble are strongly dominated in the soft X-ray band by lines from highly ionized elements. While both processes share many ...

The Ism from the Soft X-ray Background Perspective
In the past few years progress in understanding the local and Galactic ISM in terms of the diffuse X-ray background has been as much about what hasn’t been seen as it has been about detections. High resolution...

Intensity variations of the soft X-ray background: the boundary structure of the local hot bubble at low galactic latitudes
42 ROSAT PSPC pointed observations in the Galactic plane (l ∼ 4° – 26°) are mosaicked in order to study the spatial structure of the X-ray emitting gas in the Local Hot Bubble (LHB). Degree scale X-ray intensity ...

Tracing the Interstellar Medium in Ophiuchus Across 14 Orders of Magnitude in Frequency
The spectral range of ground and space-based observations has expanded rapidly in recent years. Essentially complete sky coverage is available in bands spanning more than 14 orders of magnitude in frequency, w...

A new view of the LHB and 1/4 keV X-ray halo
The X-ray sky at 1/4 keV is completely dominated by diffuse emission. It has become clear that it originates as at least three separate components: local emission within the nearest ≈ 100 pc from the Sun, halo...

Small-scale 1/4keV fluctuations due to the local hot bubble
To determine fluctuations in the 1/4 keV emission due to the LHB, without contamination due to sources within the galactic disk, the Galactic halo or the extragalactic background, we have formed a mosaic of PS...

Mission Planning with ROSAT
The mission planning activities for the satellite bourne X-ray observatory ROSAT are discussed. Responsibility is shared between the Max Planck Institute for Extraterrestrial Physics (MPE), which provides the ...

A soft X-ray image of the Moon
A soft X-ray image of the Moon obtained by the Röntgen Observatory Satellite ROSAT clearly shows a sunlit crescent, demonstrating that the Moon's X-ray luminosity arises from backscattering of solar X-rays. Th...

Simulated ROSAT observations of clusters of galaxies
Detailed simulations have been made of the search for clusters of galaxies during the ROSAT all-sky x-ray survey (0.1–2 keV). The simulations use a conservative estimate of the cluster luminosity function to c...

The ROSAT diffuse X-ray background survey
The quality and capabilities of the ROSAT survey (0.1–2.0 keV) for the study of the diffuse X-ray background and the interstellar medium are discussed. All-sky maps created from data collected during the surve...
