Title HESS J1534-571: XMM-Newton observations of an unusual new TeV SNR shell


DOI https://doi.org/10.57780/esa-8sgmkbs
Author Dr Gerd Puehlhofer
Description All TeV-emitting supernova remnant (SNR) shells that have been detected so far show strong non-thermal X-ray synchrotron emission, evidencing the presence of supra-TeV electrons. Here, we propose to observe the Southern part of the newly identified TeV SNR shell HESS J1534-571 with XMM-Newton in an exploratory 30 ks pointing, to pin down the X-ray emission from the object. Previous Suzaku pointings on the Northern part of the shell have revealed a surprisingly low level of X-ray synchrotron emission from this part of the object, which may indicate that HESS J1534-571 differs from the other known TeV SNRs and potentially exhibits hadronic TeV emission. The proposed XMM-Newton observation will scrutinize this result before strong conclusions can be drawn.

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.
