报告摘要:

Galaxies at the low-mass end of the hierarchical assembly process hold essential clues to structure formation and evolution in the Lambda CDM framework. Our current understanding of the evolution of dwarf galaxies, either the diffuse ones or compact ones, is far from complete. Among the most outstanding questions are the consequence of mergers on the evolution of dwarf galaxies, the triggering mechanisms of starburst dwarf galaxies, and the nature of compact dwarfs, etc. I will present some recent progress of my group in the observational studies of dwarf galaxies in the local Universe. Particularly, my talk will touch on stellar populations, kinematics and structural evolution of blue compact dwarfs, dwarf mergers and dwarfish compact stellar systems.
