Census of the Local Universe (CLU) Galaxy Survey: Results Within Preliminary Fields
Abstract
We present an analysis of galaxy candidates in 15 (out of ~3600) preliminary fields of the Census of the Local Universe (CLU) galaxy survey. The intermediate Palomar Transient Factory (iPTF) is undertaking the CLU project to complete our survey of galaxies out to 200 Mpc (z ∼ 0.05) and deploys 4 wavelength-adjacent, narrowband filters to search for emission line (Hα) sources across 3π (~28,000 deg^2) of the sky. Using the Palomar 200-inch Hale telescope, we have obtained spectroscopic follow-up observations with which we can verify each candidate’s redshift and derive galaxy properties. In addition, we present some interesting galaxies in our candidate list (e.g., green peas) whose extreme properties (e.g., low metallicity and high star formation rate) are similar to those of higher redshift galaxies (z>2). We will expand our analysis to all ~3600 fields and anticipate finding tens-of-thousands of new galaxies in the local Universe over the next year.
