Τίτλος: The physics of Luminous Infrared Galaxies: from Spitzer to JWST


 Luminous and Ultraluminous Infrared Galaxies (LIRGs/ULIRGs) have been 
an active area of galaxy research since their discovery as an important population
 more than three decades ago. With its vast increase in mid-infrared imaging and 
spectroscopic sensitivity, Spitzer Space Telescope played a major role in expanding
 the exploration of these galaxies in the local Universe, and pushing the study of
 dust enshrouded galaxies beyond “cosmic noon” when cosmic star formation was 
at its peak. We will highlight some of the discoveries made with Spitzer through 
observations of U/LIRGS at low and high redshift, including the quantification of 
the role of starbusts and active galaxies as power sources, direct evidence for 
energetic feedback on the atomic and molecular interstellar gas and dust, and the
 link between the sizes and spectroscopic properties of luminous infrared galaxies 
on and off the galaxy main sequence. The potential for exploring the discovery space 
with James Webb Space Telescope will also be discussed.
