We propose XMM-Newton observations of two middle-aged radio-quiet Fermi pulsarsJ0554+3107 and J0622+3749. The former is associated with the supernova remnantG179.0+2.6 which provides a great advantage for confident constraining itsdistance and evolution stage. Using Chandra, eROSITA and Swift shallow exposureswe have found their X-ray counterparts. Thermal spectral components dominatetheir X-ray emission. Measurements of the parameters of these components areimportant for comparison with neutron star cooling theories and the study offundamental properties of superdense nuclear matter inside the stars. However,any accurate conclusions are impossible due to low count statistics. We requestfor followup observations to study thermal emission from these pulsars.

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.
