Optical imaging of the recently discovered infrared quasar IRAS 00275-2859 shows that it can be decomposed into two point sources embedded in an underlying extended image. The brighter point source is the quasar; the extended image together with the fainter point source is identified as the host galaxy system. The IRAS 00275-2859 QSO 1 + host-galaxy system appear to be typical of radio-quiet QSOs. The following interpretation of the present observations is offered: IRAS 00275-2859 is an interacting system of galaxies. QSO 1 is associated with one of the galaxies and may be a direct result of the interaction. The fainter point source visible in the optical image is the nucleus of the second galaxy. The extended low-surface-brightness region is the tidal signature of the interaction. Enhanced star formation resulting from the interaction powers most of the infrared radiation. 40 references.
