Hyperluminous Infrared Galaxy

(HLIRG)
(a galaxy emitting a more far infrared than an ULIRG)

A Hyperluminous Infrared (IR) Galaxy (HLIRG) is a Galaxy emitting more than 1013 times solar Luminosity (L) in the Far Infrared (FIR). A HLIRG can be considered a type of Luminous Infrared Galaxy (LIRG), i.e., a galaxy with 1011 times solar luminosity in far infrared. A Ultraluminous Infrared Galaxy (ULIRG) has 1012 times solar luminosity in far infrared.

A LIRG is often often a Starburst Galaxy and/or has an Active Galactic Nucleus (AGN) or a Quasar (QSO).
