摘要 (Abstract): 

Future studies of dark matter (DM) will be interdisciplinary, which include cosmological and astrophysical constraints, indirect signals and direct detections. A synergy study of DM consistently with all those channels is the key to robust physics of DM. By overviewing the evidence for the DM hypothesis, I first discuss some cosmological and astrophysical probes for “model independent” DM properties, such as the “coldness” and interactions. The often-considered DM candidates, e.g., WIMP and ALP, are in tension with observations, which motivates new proposals for DM. I will talk about a recently proposed B-L gauge. The model consistent with cosmological constraints predicts a nontrivial neutrino signal potentially detectable in the future with low-energy neutrino experiments. In addition, remarks will be given on several cosmological anomalies and their DM explanation. In the future, small-scale dwarf systems and the cosmic dawn are promising for DM properties searches due to their less contaminations.
