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.
