We report new K-band, radio continuum, and CO (1-0) imaging observations and 850 micron photometric observations of PDS 456, the most luminous QSO in the local universe (z<0.3). The 0.6'' resolution K-band image obtained using the Keck telescope shows three compact K~16.5 (M(K)~ -21) sources at a projected distance of ~10 kpc to the southwest, and the host galaxy of PDS 456 may be interacting or merging with one or more companions. The observations using the OVRO millimeter array has revealed a… Expand
