| Abstract | We propose radio continuum observations of four Galactic SNRs, G28.6-0.1,G32.4+0.1, G347.3-0.5, and G353.6-0.7, with X-ray spectra dominated bysynchrotron emission. Multi-wavelength studies of these sources are essentialfor improving our understanding on how SNRs accelerate cosmic-ray particles.These SNRs are all intrinsically radio faint and require sensitive observationsto correlate radio features that produce X-ray emission. The radio observationswill allow robust determinations of the integrated flux densities at eachfrequency, along with their radio spectral indices. The L band polarizationmeasurements will determine the direction and strength of their magnetic fields.We request a 50 ksec XMM-Newton observation of G32.4+0.1, essential for modeling its broadband emission. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
