We will compare velocity profiles of LyA and H-alpha to determine the outflow velocities, and constrain absorbing columns of neutral gas.

Using the Advanced CCD Imaging Spectrometer on board the Chandra X-ray Observatory, Lopez observed the Galactic supernova remnant ( SNR ) W49B to understand the thermodynamic properties and explosive origin of the SNR . The observed electron temperature and absorbing column toward W49B suggest that the mean metal abundances are consistent with the predicted yields in models of bipolar / jet-driven core-collapse SNe.
