ISO images of starbursts and active galaxies

We present some highlights from the mid-infrared (5-16 μm) images of mergers of massive galaxies obtained with the Infrared Space Observatory (ISO). We have observed: 1) ultraluminous infrared nuclei, 2) luminous dust-enshrouded extranuclear starbursts, and 3) active galaxy nuclei (AGNs). In this co...

From these observations we conclude the following: 1) the most intense starbursts in colliding systems of galaxies and the most massive stars are dust-enshrouded in regions that appear inconspicuous at optical wavelengths, 2) the most intense nuclear infrared sources are a combination of AGN and starburst activity, 3) the hosts of radio loud AGNs that trigger giant double-lobe structures may be symbiotic galaxies composed of barred spirals inside ellipticals. 1999 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_0004640X_v269-270_n1-4_p349_Mirabel http://hdl.handle.net/20.500.12110/paper_0004640X_v269-270_n1-4_p349_Mirabel
