The CHANG-ES Results So Far

 

Abstract

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.

 

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
