Scientific paper

Using observations of 20 Type Ia supernovae obtained over the past 3 years by the Carnegie Supernova Project collaboration at the Las Campanas observatory in Chile, along with results from previously studied Type Ia supernovae, I will present Hubble diagrams and derived absolute magnitudes at maximum brightness for the objects that have well observed lightcurves in the near-infrared. Type Ia supernovae at maximum light appear to be standard candles in the near-infrared to a precision of +/-0.15mag or better.
