The precision measurements from current observational cosmology have established the Lambda-Cold-Dark-Matter (LCDM) model as the standard cosmological model. However, the LCDM model as a pure phenomenological model with six base parameters still calls for a theoretical understanding of underlying mechanisms for the early and late accelerations as well as the nature of dark matter. In this talk,...
The interstellar medium is the fuel for star formation and AGN, and the sink for their feedback energy. It also records the history of star formation in its elemental abundances. The warm ionized gas ...
