Title: Unleashing the power of JWST & ALMA – Revealing the Mysteries of Galaxies in the Early Universe
Guest Speaker: Lucie Rowland, PhD Student in Astrophysics – Leiden University & London Observatory
Summary: In this talk, Lucie talks about her big research topic, “Characterizing Massive, Star-Forming Galaxies at High Redshift with ALMA and JWST.” Ms. Rowland is an observational astrophysicist that studies Massive Galaxies, those that are 100 to 1000 x larger than the Milky Way, with ALMA and JWST. These galaxies collide with each other and get even more massive. This is a laboratory for some extreme physics. Star-forming massive galaxies will be brighter and will have bright emission lines. Lucie studies massive bright galaxies with redshift z greater than 6, which is known as the re-ionization era. ALMA is an interferometer telescope that operates at wavelengths of 0.32 to 3.6mm, while JWST operates in near to mid-infrared wavelengths.
This is a fascinating opportunity to learn how observational astronomers use ground-based and space-based telescopes to study high redshift galaxies. We hope you enjoy it!
