Title JVLA Observations of Galactic SNRs with Synchrotron Dominated X-ray Spectra


DOI https://doi.org/10.57780/esa-j2kubbn
Author Dr Christina Lacey
Description 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 by synchrotron emission. Multi-wavelength studies of these sources are essential for improving our understanding on how SNRs accelerate cosmic-ray particles. These SNRs are all intrinsically radio faint and require sensitive observations to correlate radio features that produce X-ray emission. The radio observations will allow robust determinations of the integrated flux densities at each frequency, along with their radio spectral indices. The L band polarization measurements 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 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.
