The Arecibo Pisces-Perseus Supercluster (APPS) Survey

In visualizations of the large scale structure within 100 Mpc, the Pisces-Perseus Supercluster (PPS) represents a strong overdensity, separated from the local Laniakea supercluster by a deep void. The PPS extends over 50 degrees of the Arecibo sky at a near-constant distance of 70 Mpc. Here, we propose to extend the results of the ALFALFA survey by conducting LBW HI-line observations of galaxies which are likely, based on photometry derived from SDSS and GALEX, to be PPS members, but which lie below the ALFALFA detection limit. Previous LBW observations under A2811 and A2859 have demonstrated the efficacy of this approach to increase the HI dataset by 50%. In addition to tracing the HI mass function to log MH = 8, we will use the Tully-Fisher relation to make a robust measurement of infall onto the PPS for comparison with flows predicted by constrained simulations.
