An eponymous term used in cosmology, occasionally referring to the period of time associated with the observable universe's expansion or the work of the astronomer Allan Sandage.
Linguistics
Semantic Notes
This is a highly specific, eponymous term. It is not a general English word and is almost exclusively found in cosmological literature or historical discussions of astronomy. It functions as a proper noun when referring to the astronomer and a countable noun (a sandage, several sandages) in its technical usage.
