Solitary dwarf galaxy groups as tracers of primordial dark matter halos in the local Universe
Z. S. Yuan, Z. L. Wen, J. L. Han
In CDM cosmology, galaxies and clusters form within dark matter halos and merge in the hierarchical assembly paradigm to form massive systems. Using the released optical survey…

A rare sextuple-merging brightest cluster galaxy system in a disturbed galaxy cluster observed with the Einstein Probe Follow-up X-ray Telescope
Z. L. Wen, S. M. Jia, Z. S. Yuan +12
The evolutionary processes of galaxy clusters influence the properties of their member galaxies. We present a joint X-ray--optical analysis of the galaxy cluster WHY J050106.2+0137…

A sample of 3403 galaxy clusters identified in XMM-Newton X-ray images
Z. S. Yuan, Z. L. Wen, W. Xu +1
Currently, the number of galaxy clusters identified using galaxy data has far exceeded the number derived from intracluster medium data. In this study, we used positional informati…
