Abstract: We present preliminary results from a multi-wavelength study of a merger candidate, NGC 3801, hosting a young FR I radio galaxy, with a Z-shaped structure. We find two HΙ emission blobs on either side of the host galaxy, suggesting a 30 kpc sized rotating gas disk aligned with stellar rotation, but rotating significantly faster than the stars. Broad, faint, blue-shifted absorption wing and an HΙ absorption clump associated with the shocked shell around the eastern lobe are seen, possibly due to an outflow. While dust emission is seen on a large scale, partially coinciding with the HΙ emission blobs, it reveals a ~2 kpc radius ring-like dust structure in the nuclear region, orthogonal to the radio jet axis.
