Description

In this study we looked at eight narrow-line Seyfert 1 (NLS1) galaxies in $J-$ and $Ks-$ bands. The data was gathered with the FourStar instrument of the 6.5 m Magellan Baade telescope at the Las Campanas Observatory (Chile). The purpose of this study is to identify the host galaxy morphologies of each source by using GALFIT. So far, we have modeled four sources using GALFIT and continue working on the remaining sources.
