Scientific paper

We present a homogeneous set of over 30 well sampled, low redshift, near-infrared (NIR) JHKs band light curves of Type Ia supernovae (SNe Ia) observed from 2004-07 with the fully robotic 1.3m Peters Automated Infrared Imaging Telescope at Mount Hopkins, Arizona. We confirm that SNe Ia are superior standardized candles in the NIR vs. optical wavelengths, with combined optical and NIR data yielding significantly improved reddening measurements and distance estimates. Our work motivates designing detectors sensitive beyond 1.7 μm for future satellites optimized for high redshift SNe Ia cosmology, with strong implications for both the mission design and cost of the planned NASA/DOE Joint Dark Energy Mission.
