Query: Comparisons of Type Ia Supernova Light Curves in the UV and Optical with
  the Swift Ultra-Violet/Optical Telescope   We examine the light curve parameters of 97 nearby Type Ia supernovae in the
ultraviolet and optical using observations from the Swift Ultra-Violet/Optical
Telescope. Our light curve models used a linear combinations of templates,
which were based on Functional Principal Component Analysis of the optical
photometry of SNe Ia. The weights for each principal component used in the fit
capture certain aspects of the light curve properties. We find that there is
little difference in the overall variability of principal component scores
across filters. We also find correlations between certain filters and PC
components, indicating that the UV and optical properties seem to be tied
together. This is a promising step in UV SNe Ia analysis, and suggests that UV
light curves may be used to infer optical properties, paving the way for future
cosmological studies.
