Denison University’s 178th Commencement took place on Saturday, May 18. Watch the ceremony in its entirety including commencement keynote speaker Jennifer Garner ’94.
Jillian Scudder (Oberlin College) will present, “The Hunt for Cosmic Monsters: Understanding Galaxies in the Confused FIR Sky,” when she visits on March 1.
Observing galaxies in the Far-Infrared (FIR) gives us a unique window into the star formation rates of high redshift, dusty galaxies. These galaxies are generally thought to be forming stars at a prodigious rate, heating their dust within their host galaxy, which then radiates in the FIR. However, observing this luminous dust is difficult, even with a space-based telescope such as the Herschel Space Observatory, as the resolution of the images returned is quite poor. It is often assumed that a bright source in the FIR belongs to a single, highly star forming galaxy, but this is impossible to verify with low resolution images. In this talk I will discuss a method of determining how many galaxies are blurred together into a single FIR detection, and what these results imply for our understanding of star formation in the younger Universe.
