Radio Halos of Galaxies

1 - 5 July 2013

Venue: Lorentz Center@Snellius

With the Expanded Very Large Array (EVLA, now the Karl G. Jansky VLA) upgrade to sensitive, wide-band receivers, we have a new opportunity to exploit these new capabilities to search for faint galaxy halos.  Our consortium, “Continuum Halos in Nearby Galaxies -- an EVLA Survey (CHANG-ES) has received 405 hours of EVLA time to observe 35 edge-on galaxies at 20 and 6 cm wavelengths.  This Snelius Center meeting will be the first face-to-face meeting of the entire consortium at a time when all EVLA data (and some supplementary Greenbank Telescope data at the same wavelengths) have been obtained. 

Our science goals include probing the origin of and physical conditions in galaxy halos, searching for clues on lagging halos, understanding cosmic ray transport and wind speed, mapping magnetic fields in galaxy disks and halos, extending the far-infrared - radio continuum relation into halos, providing input for high-energy (gamma ray) models, and developing a repository of publicly-accessible 'legacy-value' radio images for future study.

The goals of the workshop are to share new results, generate and develop ideas for maximum scientific output of the group, provide hands-on data reduction guidance, develop specific strategies for the presentation of scientific data in a timely fashion, and provide an organizational framework for the public release of processed images.
