Description	In the context of exploring mass distributions of dark matter haloes in giant ellipticals, we extend the analysis carried out by Merrifield & Kuijken (1998) for stellar line profiles of shells created in nearly radial mergers of galaxies. We show that line-of-sight velocity distributions are more complex than previously predicted. We simulate shell formation and analyze the detectability of spectroscopic signatures of shells after convolution with spectral PSFs.
