Join Carnegie Science Observatories astronomer Jeff Rich, who will discuss the Webb Telescope observations of ultraluminous infrared galaxies and how these discoveries will lead to a new understanding of supermassive black holes, massive star clusters, and more.
The James Webb Space Telescope's ability to probe galaxies at infrared wavelengths in great detail has led to an unprecedented view of ultraluminous infrared galaxies (ULIRGs). ULIRGs are the brightest objects in the nearby universe, glowing with the light of hundreds of trillions of stars. This extreme brightness is caused by the mergers of Milky Way-sized galaxies that produce an intense burst of star formation and black hole growth. Jeff Rich will discuss the discoveries that the Webb Telescope observations of ULIRGs have yielded, and how these will lead to a new understanding of supermassive black holes, massive star clusters, and changes in the interstellar medium.

About the Speaker:
Jeff Rich is an astronomer at the Carnegie Science Observatories, as well as the Observatories’ outreach and education coordinator. His research focuses on observations of nearby galaxy mergers to understand how galaxies evolve throughout cosmic time. Rich received his undergraduate degree at the University of Southern California, and his M.S. and Ph.D. degrees at the University of Hawai'i.
