Infrared galaxies as a research area focuses on galaxies whose emission is dominated by infrared radiation, typically arising from dust-reprocessed starlight and, in some cases, active galactic nuclei (AGN). This field investigates the physical conditions of interstellar dust, star-formation rates and efficiencies, obscured starburst activity, and the role of dust-enshrouded AGN in galaxy evolution. Studies use multiwavelength observations, spectral energy distribution modeling, and infrared spectroscopy to probe heavily obscured regions inaccessible at optical wavelengths, constrain the cosmic star-formation history, and understand feedback, gas accretion, and merger-driven processes in both local and high-redshift infrared-luminous galaxy populations.
Located 12 million light-years away and undergoing rapid star formation, edge-on spiral galaxy Messier 82 (M82) is a scientifically unique sight to behold, and now NASA's James Webb Space Telescope has revealed previously ...
