SUMMARY:Bayesian Identification of Global 21cm Signal Depth Origin - Domin

DESCRIPTION:Theoretical models have suggested that the depth of the Global
  21cm signal could be enhanced beyond that of standard astrophysics by the
  presence of excess radio backgrounds or excess cooling of the intergalact
 ic medium. However\, these two effects will manifest similarly in the 21cm
  signal itself\, making them hard to distinguish from the signal alone. In
  this talk\, I will discuss a potential method for telling these two cases
  apart via physical modelling of the foreground components\, in order to i
 dentify the presence or absence of an excess background component in those
  foregrounds.
