Title: The Heart of Darkness: Finding and Characterizing Star-Forming Galaxies in Extreme Voids
Abstract: Galaxies within voids are expected to have less gas accretion and less harassment from neighbors than galaxies found in dense regions of the large-scale structure. Void galaxies might, therefore, look different from the average galaxy in global properties such as mass, star-formation rate and metal abundance. Further, simulations of large scale structure predict the existence of more galaxies than are currently seen in voids. This may be due to the fact that void galaxies are hard to pick out among the large number of foreground and background galaxies along the line of sight. We propose a novel technique to identify galaxies in voids using narrow-band filters currently available on the KPNO Mosaic camera. Once we have identified void candidates we will request spectroscopy to confirm their redshift and characterize their properties.
