0 Assigned ID: 664 ----- Attempting Submission 1 (Fri Apr 10 18:47:22 GMT 2015) ----- HST Phase I Proposal 664 (void_23.apt) successfully submitted. Receipt: # 664-1 I was requested by Crystal Mannfolk to change the exposure pattern on the WFC3/IR exposures to increase the NSAMPs in Visit 2. Only that has been changed. -2143380458 ----- Attempting Submission 1 (Mon Jul 13 20:34:21 GMT 2015) ----- ----- Attempting Submission 2 (Tue Sep 22 16:08:26 GMT 2015) ----- Draining the Local Void From the theory of the growth of structure it is anticipated that material rushes away from the centers of voids at velocities that depend on the cosmological parameters Omega_m and H_0, how empty the void is, and the radius from the center. If dark energy has a variable equation of state it may pool in voids and add to outflow velocities. The Local Group resides on the boundary of the very large Local Void and it has been determined that we have a peculiar motion of 260 km/s away from the void. Though the Local Void is mostly empty, it does contain a few lonely galaxies. For those that are nearby, accurate distances can be determined from resolved images through identification of the Tip of the Red Giant Branch. Accurate distances allow the determination of accurate peculiar velocities. Serendipidously, one galaxy in the void has been studied and it has a peculiar velocity of 300 km/s away from the void center. An Arecibo Telescope survey recently discovered an excellent target in the Local Void. This interesting galaxy will be studied with this program to afirm if void galaxies systematically have large velocities of expansion from the void center and, incidentally, to investigate the star formation and metallicity properties of this isolated galaxy. The important void expansion test of the theory of the formation of large scale structure can only be made locally, where peculiar velocities dominate Hubble velocities. It is fortuitous that we live adjacent a very large void. We will use one orbit to observe KK246 = ESO 461-36 with WFC3/IR in the F110W and F160W filters. We wil observe ALFAZ0AJ1952+1428 with ACS in the F606W filter for two orbits and in the F814W filter for two orbits using a box pattern.
