Abstract: Galaxies clusters, such as the largest structures in the universe located at the top of the cosmological hierarchical model, are useful tools for understanding the evolution of the universe. For various research through galaxy clusters in statistical terms, the catalogue with cluster information plays basically an important role. A large number of catalogues for galaxy clusters in the northern sky have been published; however, there are few catalogues in the southern sky due to the lack of broad sky survey data. The KMTNet Synoptic Survey of Southern Sky (KS4), which observes a wide area of the southern sky of about 4500 deg2 with KMTNet telescopes for two years, is running under the SNU Astronomy Research Center in Korea. We detect galaxy clusters at z < 0.8 using the red sequence method of KS4 data release (DR1). This new catalogue of galaxy clusters will improve the study of galaxy clusters in the southern sky.
