| Abstract | In the last several years, tremendous progress from the SZ surveys like Planck,SPT and ACT has made the SZ observation an important means for the studies ofthe ICM and cluster cosmology. While ground SZ telescopes are generally onlysensitive to and are focused on rich clusters, Planck can detect poor clustersand even groups at z<0.05, as shown by the 2013 Planck cluster catalog. Weselect a sample of 26 poor clusters and groups detected by Planck at z<0.05. Sixof them have no XMM or Chandra data and two of these six clusters are not evendetected by RASS. We propose to observe these six systems with XMM to have acomplete sample of Planck low-mass systems to extend the Planck scalingrelations to a mass scale that is 4 - 5 times lower than what was achieved before. |

| 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. |
