Dust-Obscured Activity in High Redshift Galaxies


Alexandra Pope (University of Massachusetts)



Mitchell Institute for Fundamental Physics & Astronomy

College Station, Texas 77843

Event Details

We now know that the majority of the star formation activity at high redshift occurs behind dust. Building on the success of the first extragalactic submm surveys over a decade ago, Dr. Pope will discuss recent observations with Spitzer and Herschel that have advanced our understanding of dust emission in high redshift galaxies. These observations constrain how intense star formation and active galactic nuclei growth are linked in major mergers and turbulent gas-rich disks that are orchestrating massive galaxy formation. Dr. Pope will also present evidence for evolution in dust properties suggesting different interstellar medium conditions at high redshift. She will discuss the evolving role of environment in moderating dust obscured activity. Finally, Dr. Pope will show how future large dish (sub)millimeter facilities will directly detect the majority of the sources contributing to the infrared background allowing us to make a complete census of dust-obscured activity in the Universe.
