| Abstract | Understanding the cluster selection function is a key feature to use galaxycluster samples as cosmological probes. Thanks to the multiwavelength coverageof larger areas of the sky, we are now in a position to compare galaxy clustersamples selected by independent methods to understand better their underlyingcluster population. Thanks to the eROSITA coverage of a HSC shear-selectedcluster sample, we characterised their X-ray properties, finding that theweak-lensing peak sample shares all properties of an X-ray selected sample.However, there are three X-ray faint shear-selected clusters that lie outsideour expectations, and for which we propose deeper observations to understandtheir nature and help us to understand better the X-ray and weak-lensing selection functions of galaxy 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. |
