IRAS 00521 - 7054 is a galaxy that lies behind the Small Magellanic Cloud. Its infrared energy distribution is quite unusual in that it has exceptionally red 0.6-10-micron colors, while its 12-100-micron spectrum is among the warmest known for a galaxy or quasar, with a peak at 25 microns and an integrated luminosity of close to 10 to the 12th solar luminosity. Its optical spectrum is characteristic of a Seyfert 2 galaxy: low-ionization forbidden lines and H-alpha have FWHM 500 km/s, with some evidence for a much broader component of the H-alpha line. A plausible model is that a central nonthermal source is the dominant source of luminosity, but it is heavily obscured by dust and is thus observed indirectly through reradiation of its flux by the surrounding material. This galaxy may then be a good example of an object in the process of developing into a 'classical' quasar.
