Therefore, they are key to our understanding of how the bulk of matter in the Universe accretes and forms hierarchical structures and how different sources of feedback affect their gravitational collapse. However, despite their crucial role in cosmic structure formation and evolution, galaxy groups have received less attention compared to massive clusters. This is perhaps in part due to their rarity in being observed and properly characterized. With the advent of eROSITA, many thousands of galaxy groups will be detected by X-ray, complementing optical and SZ coverage. In this Special Issue we collected and organized the latest developments in our understanding of these systems and present future prospects from both observational and theoretical points of view.Research & information: generalbicsscfossil galaxy groupsgalaxy clustersgalaxy groupsX-ray and optical observationshydrodynamical simulationsintragroup medium/plasmaactive galactic nucleiblack holeselliptical galaxiesactive nucleiX-ray observationshydrodynamical and cosmological simulationsgalaxies:abundancesgalaxies:clusters:intracluster mediumX-rays:galaxiesgalaxy surveysUV observationscosmological parametersResearch & information: generalLovisari Lorenzoedt1300053Ettori StefanoedtLovisari LorenzoothEttori StefanoothBOOK9910557684203321The Physical Properties of the Groups of Galaxies3025377UNINA
