CHANG-ES (Continuum Halos in Nearby Galaxies — an EVLA Survey) is a survey of edge-on galaxies that reveals their radio halos, cosmic ray transport, as well as the interaction between the star forming disk and the extended halo. CHANG-ES observed 35 edge-on spiral galaxies in the local universe using the Karl G. Jansky Very Large Array at two frequencies: 6 GHz (C-band) and 1.6 GHz (L-band).

The 2019 CHANG-ES International Workshop on CGM Science Frontiers will take place from May 13th to May 18th at the Tsung-Dao Lee Institute(TDLI) in Shanghai (internal) and the Purple Mountain Observatory in Nanjing (public). More information and registration can be found CHANG-ES 2019

TITLE BACKGROUND IMAGE: Composite image of an edge-on spiral galaxy with a radio halo produced by fast-moving particles in the galaxy's magnetic field. In this image, the large, grey-blue area is a single image formed by combining the radio halos of 30 different galaxies, as seen with the Very Large Array. At the center is a visible-light image of one of the galaxies, NGC 5775, made using the Hubble Space Telescope. This visible-light image shows only the inner part of the galaxy's star-forming region, outer portions of which extend horizontally into the area of the radio halo.
