| Abstract | With the increase in sensitivity and resolution of the radio observations, insome late-type galaxies the so-called magnetic arms have been detected inthe interarm regions. Such magnetic arms are places of high ordering of themagnetic field. In We.zgowiec et al. (2016, AA, 585, A3), we presented thatthe strongly polarized radio emission, as well as a slight increase in thetemperature of the hot gas in the areas of the magnetic arms of NGC,6946 may becaused by the magnetic reconnection processes. To further investigate thisphenomenon we selected a sample of galaxies that show the magnetic arms andallow a detailed spectral analysis of the X-ray emission. The most exceptionalamong these galaxies is NGC,628, with by far the lowest rotation velocity. |

| 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. |
