Missing weak-lensing peaks in the eFEDS sample
收藏资源简介：
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 able to compare cluster samples selectedby independent methods to understand better their underlying cluster population.Thanks to the eROSITA coverage of a HSC shearselected cluster sample, wecharacterised their Xray properties, finding that the weaklensing peak sampleshares all properties of an Xray selected sample. However, there are threeXray faint shearselected clusters that lie outside our expectations, and forwhich we propose deeper observations to understand their nature and the Xrayand weaklensing selection functions of galaxy clusters. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
