Abstract: Active galactic nuclei (AGN), which represent the rapidly growing phase of the supermassive black holes (SMBH), radiate across the whole electromagnetic spectrum from radio to Gamma-rays. X-rays, which are seen in most AGN, are an important tool to study the physics of AGN. Thanks to the launch of NuSTAR in 2012, we are able to probe AGN properties in the hard X-ray regime for the first time. In this presentation, I will introduce our recent progress on different aspects of AGN, including the properties of the AGN dusty tori, X-ray emitting corona, and AGN demographics.
