... The set of D30 new, unпltered CCD observations delineate the early rise behavior of SNe Ia 18 to 10 days before maximum. ... Using a variety of light-curve shape methods, we пnd the rise time to B maximum for an SN Ia with *m (B) \ 1.1 mag and peak M \[19.45 mag to be 19.5 ^ 0.2 days. ... OBSERVATIONS 2.1. ... 118 V B mag 20 -20 -10 0 10 Age (Days) 20 FIG. 4.хL eft : Observed V -band light curves for 10 SNe Ia including rise-time observations transformed from unпltered CCD measurements. ...

... Many years ago, while lying on her back on a friend's boat in Long Island Sound, Lynn saw a sky awash in stars, and decided to learn more about astronomy. ... Lynn was a Renaissance woman. ... The mission is part of the broader NASA's Living With a Star (LWS) program, conceived t o explore fundamental processes that operate throughout the solar system and in particular those that generate hazardous space weather effects in the vicinity of Earth and phenomena that could impact solar system...

... Up: Image Restoration . ... The novelty of our approach to the superresolution problem is the use of wavelets and related multiresolution methods within an expectation-maximization reconstruction process to improve the accuracy and visual quality of the reconstructed image. ... We present a new method for superresolution image reconstruction based on the wavelet transform in the presence of Gaussian noise and on an analogous multiscale approach in the presence of Poisson noise. ...
