One of the key outstanding problems in studies of galaxy evolution is understanding the connection between AGN and star formation (SF). Nevertheless, finding the existence of an SF-AGN connection is still not clear which process dominates the energetic output in both local and high redshift Universe. We present 360 X-ray selected obscured (type 2) AGNs at redshift z < 1.5. We acquired star formation properties for those X-ray detected AGN which available in the Cosmological Evolution Survey (COSMOS) project. We compared the star formation properties for our X-ray detected AGNs and non-X-ray galaxies using starburstiness. The step further is analyzing the X-ray properties and starburstiness of X-ray detected AGN for proving the existence of a connection. The starburstiness distribution of X-ray detected AGNs shows some excess in low star forming activity compared with the non-AGN objects. This excess might be an interesting topic to analyze the AGN type. For X-ray detected AGNs, We found that X-ray activities arise both in high and lower star forming activity. From those properties relation, we conclude that the AGNs could be triggered by starburst either directly or delayed.
