Title Mach cones around Virgo Cluster spiral galaxies


DOI 10.5270/esa-lo6n5cj
Author Dr Marek Wezgowiec
Description The detailed comparison between observations and simulations of ram pressure stripped spiral galaxies in the Virgo cluster has led to a three dimensional view of the galaxy orbits within the hot intracluster medium. The 3D velocities and Mach numbers derived from these simulations can be used to derive simple Mach cone geometries. We see indications of these Mach cones in the large-scale X-ray emission of existing XMM-Newton data. However, the data are not deep enough to establish a clear cone structure. Therefore, we propose high sensitivity X-ray observations of selected Virgo Cluster spiral galaxies. The observations of NGC,4388 were approved in AO9 with a C-priority. However, this has not been scheduled yet and there is no guarantee it will be done.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
