FSC15307+3253 (or IRAS F15307+3252)[2] is an ultraluminous infrared galaxy (ULIRG), with a luminosity between 8 and 1000 μm of approximately 2×ばつ1013 L, possibly the highest currently known. The "FSC" refers to Faint Source Catalogue , one of the source catalogs produced by the IRAS infrared survey mission. The emission is believed due to some combination of starburst activity and accretion onto a super-massive black hole, producing primary radiation at shorter wavelengths which is mostly blocked by obscuring dust, which is in turn heated and re-radiates in the infrared. The redshift of the source is z = 0.93,[2] indicating a distance of the order of 7 billion light years.
