The Life Cycle of Hydrogen by Erika Hamden (University of Arizona)

Date: 
Wednesday, November 13, 2019 - 3:30pm
Series: 
Astronomy/Astrophysics Colloquium

Abstract: In this talk, I will discuss my ongoing research efforts to map, measure, and understand diffuse hydrogen in a range of environments from the circumgalactic medium of high-z galaxies and groups, lower redshift CGM observations, down to local star forming regions in our own galaxy. As part of this work, I will discuss the importance of using instruments that already exist (KCWI on Keck); new missions currently being built or re-built (KCRM and FIREBall-2); and totally new mission concepts (Hyperion, a SMEX-class mission proposed this summer). I will describe some of the challenges and rewards of building hardware and a few key insights for people interested in the process of how to build a telescope.Abstract: In this talk, I will discuss my ongoing research efforts to map, measure, and understand diffuse hydrogen in a range of environments from the circumgalactic medium of high-z galaxies and groups, lower redshift CGM observations, down to local star forming regions in our own galaxy.
