When accounting for the total radiation budget from cosmic history (stars and black holes), where does the re-emitted energy, after absorption by dust, primarily peak?

Answer

In the infrared wavelengths

Energy converted from matter into radiation by stars and black holes throughout cosmic history, much of which is absorbed by dust, is re-emitted peaking in the infrared wavelengths.
