Description
The multi-component matched filer (MCMF) cluster confirmation framework, designed to leverage the synergies between ICM-selected cluster surveys and optical imaging surveys, has been applied to some of the largest and high-quality surveys to date with a focus on high purity and well controlled cluster samples for cosmological purposes. MCMF confirmed cluster catalogs have subsequently been used for the eROSITA-based eFEDS cluster cosmology as well as for the most recent cosmological results from SPT.
Besides a general overview of the MCMF family of cluster catalogs, I will present results and current status of several science projects based on ACT-DR5 MCMF and RASS-MCMF catalogs, currently the largest SZ and second-largest X-ray cluster catalogs available. Key topics include CMB lensing from galaxy clusters, cluster-based void samples, and cluster cosmology with samples of approximately 5,000 clusters, representing a fivefold increase over our most recent SPT-based cosmological analysis.
I will conclude with results from a pilot study applying MCMF to the latest dataset from the Euclid mission (Q1), demonstrating its potential for cluster confirmation at high redshifts. These findings provide an outlook on how Euclid will significantly improve the ability to confirm high-redshift clusters expected from next-generation SZ surveys, such as SPT-3G and the Simons Observatory.
