      I will overview the astrophysical importance of galaxy rotation curves in understanding galaxy formation and evolution over the cosmic time. Particularly, I will discuss what we have learned about the central dark matter distribution in galaxies from high-resolution HI 21cm observations in tandem with cosmological hydrodynamic simulations of galaxies. The observed dark matter distribution with a sizeable constant density-core towards the centres of the galaxies is more in line with those in Lambda Cold Dark Matter (LCDM) simulations of dwarf galaxies in which the effect of baryonic feedback processes is included. I will finish the talk by re-emphasising the use of galaxy rotation curves in studying galaxy dynamics and its link to star formation in the upcoming Square Kilometre Array (SKA) era.
Note: The talk will be given in Korean with English slides, mainly for undergraduate/graduate students (but all are welcome).
