A Luminous Infrared Galaxy (LIRG) is a type of galaxy that emits a significant amount of its energy in the infrared spectrum. These galaxies are typically characterized by high star formation rates, often exceeding 1 solar mass per year. The intense star formation is usually fueled by the interaction or merger of galaxies, leading to increased dust and gas that absorb visible light and re-emit it as infrared radiation. LIRGs are important for understanding galaxy evolution and the processes that drive star formation. They are often studied using infrared telescopes, such as the Hubble Space Telescope and the James Webb Space Telescope, which can detect the infrared emissions that are not visible to the naked eye.
