The Properties of Optically-Visible Star Clusters in Luminous Infrared Galaxy Mergers
Abstract
Luminous Infrared Galaxies (LIRGs) are gas-rich galaxies in the process of interacting or merging. As a result of the interaction, they can produce star formation rates up to 100 times higher than the Milky Way Galaxy. The present work shows a dendrogram analysis of the local LIRG VV 114 using a Hubble Space Telescope 0.4 micron image. Specifically, the program Astrodendro was used to identify, and measure the brightness and sizes of star-forming regions. Finally, various methods were tested in order to distinguish the best way to perform background subtraction, and then find the true flux, of the star forming regions.
