About

Welcome to the KICP seminars page! This seminar series is hosted by the Kavli Institute for Cosmological Physics at the University of Chicago. Our goal is to give early career scientists a venue to share their work and connect to the KICP and UChicago community. We invite speakers from all over who have interest in understanding the evolution of the Universe and it's laws. This includes topics in CMB, Dark Energy, Dark Matter, Astroparticle Physics, Structure Formation, and beyond.

Title: Missing Giants: The First Massive Galaxies Are Dust-Obscured
Abstract: Half of all cosmic starlight is absorbed and reprocessed by dust, which means that the widely-accepted cosmic history generated by visible-light telescopes is incomplete. The consequences of our biases are apparent in our most modern cosmological simulations: they struggle to produce sufficient populations of massive galaxies to match observations of the first 2 Gyr of the Universe. These giants likely underwent rapid, violent, and bursty phases of star formation in order to reach such extreme masses, so early on. Such rapid stellar growth produces an overabundance of dust that obscures starlight, rendering the galaxies near-invisible at UV/optical wavelengths. In this work, I compile empirical data on massive, dusty, star-forming galaxies to create a numerical model that re-derives the primary function describing stellar mass assembly in the Universe: the stellar mass function (SMF). With my model, I extend the massive end of the SMF and show that, to first order, we can successfully reproduce the rapid build up of the massive quiescent galaxy population at z > 1 — aka the predicted descendants of dusty, star-forming galaxies. I detail the impact of this model on our understanding of massive galaxy formation and cosmic stellar mass assembly, and I briefly review how current and next-generation telescopes will play a key role in this endeavor.
