TeV gamma-ray emission was recently detected from the direction of theshell-type supernova remnant G15.4+0.1 by H.E.S.S. The TeV morphology suggests acenter-dominated source at these energies, which suggests that H.E.S.S. may beobserving emission from a pulsar wind nebula located within the shell-like radioboundary of the SNR and that G15.4+0.1 is actually a composite SNR. The observedTeV flux implies an X-ray flux well within the sensitivity of XMM-Newton, evenat low levels of the ambient magnetic field. Therefore, as a part of an ongoingmulti-wavelength effort, we propose to observe this source with XMM-Newton withthe primary aim to detect the putative pulsar wind nebula inside G15.4+0.1 inX-rays and thus establishing this SNR as a composite.

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.
