Abstract

The High-Altitude Water Cherenkov (HAWC) observatory is highly suitable for large-scale survey work. The high duty time (95%), large instantaneous FoV (2 sr), and sensitivity over the 300 GeV to more than 100 TeV energy range make it ideal for creating a catalog of very high energy (VHE) sources. Over the lifetime of the HAWC observatory, 4 catalogs have been produced 3 of which were constructed utilizing the full HAWC energy range while another used a restricted (>56 TeV) range. This talk will focus on the status of the planned 4HWC (full energy range) catalog including the newly developed Multi-Source Fit algorithm inspired by the Fermi Extended Source search method for the galactic plane. Using at least an additional 1000 days of data, improved event reconstruction algorithms using HAWC's newly completed fifth pass through its dataset, and the improved search algorithm we expect to see a major improvement in the sensitivity and accuracy compared to previous catalogs. Additionally, this talk will present preliminary results from tests of the algorithm in "Benchmark" regions in HAWC data, including but not limited to, the Crab Nebula and The Cygnus Cocoon.
