99% Invisible: Uncovering the dusty galaxies which lie beneath the confusion noise floor
Marco Viero, Caltech
The vast majority of the infrared-emitting galaxies which make up the cosmic infrared background are unresolved due to confusion noise. I will present techniques to uncover key properties of this confused population, namely their average flux densities and clustering behavior, and show recent results from HerMES. Lastly, I will present two new Herschel/SPIRE fields, 150deg2 of which overlap with the SDSS Stripe 82, along with anticipated science topics.
