The CHANG-ES Results So Far



The CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) is a large program (> 400 hours) designed to investigate the disk-halo interaction of nearby edge-on galaxies.  With 3 array configurations (B, C, and D), two frequencies (1.5 and 6 GHz), and all polarization products, CHANG-ES was designed to focus on the details of disk-halo dynamics and include magnetic field information.  More than 100 hours of GBT time have also been obtained in order to recover the zero-spacing information.  At present, 11 papers have been published under the CHANG-ES moniker, the D-array data set has been publicly released and the C and B-array data sets are forthcoming.  This talk will review the results to date, including some that are surprising and unexpected.
