| Abstract | We propose 294 ks XMM-Newton EPIC observations on 15 X-ray luminous galaxyclusters detected in the first eROSITA All Sky Survey, and are in the footprintsof Sunyaev-Zeldovich (SZ) surveys but without SZ detections. The m500 of the 15clusters scaled from X-ray luminosities are all >6e14 Msol, which lie in a highcompleteness range of the two SZ surveys, addressing questions relating to thecompleteness and selection biases in SZ and X-ray surveys. We will use theproposed data to obtain hydrostatic mass to investigate the selection biases inSZ and X-ray surveys and their impact on cosmology studies. Moreover, we willalso measure other thermodynamic properties to explore the origins of SZnon-detections and discover new strong cool core clusters. |

| 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. |
