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.
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...
A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion years after ...
