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.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected a distant galaxy designated MACS0416_Y1. Results of the observations, presented Nov. 11 on the arXiv pre-print ...
An international team of astronomers has used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a well-known quasar known as the Cloverleaf. As part of the observations, they serendipitously discovered a ...
In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA's powerful James Webb Space Telescope (JWST), they identified 300 ...
