Galaxy Clusters 2022: Challenging Our Cosmological Perspectives

Galaxy clusters are the densest galaxy environments in the Universe and provide us with important insights into many fundamental astrophysical processes. They are essential laboratories for studying gravity, dark matter, cosmology, interactions between galaxies, the intracluster gas and stars, and the cycling of baryons into and out of galaxies. 

Recent multi-wavelength observations have enabled significant progress in our understanding of cluster formation and evolution, delivering more complete samples of clusters and finding ever more distant clusters and protoclusters. However, this is only the starting point. There will be an explosion of multi-wavelength data from the existing and upcoming cluster programs from facilities such as eROSITA, ALMA, ACT, SPT, the Dark Energy Survey, Subaru's HSC-SSP, Euclid, Rubin Observatory's LSST, SPHEREx, the Roman Space Telescope, and the Simons Observatory. Wide-area multi-object spectroscopic surveys are providing extensive redshift coverage of clusters out to z = 0.5 and beyond, enabling new lines of research.  JWST will further revolutionize our ability to obtain deep spectroscopy and near-infrared data to probe the properties of distant cluster galaxies in unprecedented detail. All of these observations will need to be interpreted with a new, richer generation of more precise simulations of cluster assembly in ever larger volumes. 

This symposium will provide a forum for researchers to discuss recent results and future perspectives in the study of galaxy clusters. Topics to be discussed include cluster cosmology, cluster surveys and detection, cluster mass estimation, gravitational lensing and analyses of cluster substructures, environment-driven galaxy evolution, baryon cycling, connections to large-scale structure, results from new large-scale simulations, and the challenges of analyzing cluster data across many wavelengths and over a large span of cosmic time.

The Space Telescope Science Institute will hold a fully virtual symposium beginning Monday, April 25, 2022 through and including Friday, April 29, 2022. The Symposium will include invited reviews and regular/short contributed talks and posters selected from abstract submissions.

Registration
There is no registration fee to attend the Symposium. All participants will need to register for the Symposium. Registration will be open from March 1-25, 2022. Submission of a poster or talk abstract does not register submitters for the Symposium. Registration is a separate process.
