2026 CHANG-ES Meeting
CHANG-ES (Continuum Halos in Nearby Galaxies — an EVLA Survey) is a large project to observe 35 edge-on galaxies using the Expanded Very Large Array (EVLA, now known as the Karl G. Jansky Very Large Array) covering the frequency range from 1-7 GHz (L-, S-, C-Band)
The observations have been carried out in multiple array configuration, ensuring the detection of diffuse radio emission. All polarization products have been obtained which provide maps of total intensity, linear polarization, and polarization angle. These data form the most comprehensive data set yet available for the study of nearby edge-on galaxies.
Our scientific goals encompass a variety of objectives involving galaxy disks, disk-halo outflows, and broader-scale halos. These include:
- understanding the physics of outflowing gas
- mapping vertical structures and seeing how they may relate to in-disk star formation or magnetic field strength and direction
- determining the infra-red/radio continuum relation as a function of position
- separating thermal from non-thermal emission
- following cosmic ray transport
- correlating the observed continuum features with known lagging halos
- isolating active galactic nuclei, where present
The 2026 CHANG-ES group meeting in Hamburg will present the latest findings published by the CHANG-ES collaboration and promote discussion both within the collaboration and with external guests.
