Welcome to the CHANG-ES data release web site.

Data Release 1 (DR1) is now available consisting of all images from the D configuration of the Very Large Array.  NEW (May 10, 2017): The VLA has updated its primary beam (PB) parameters. Tests have shown that this makes no difference to our L-band data and only small differences to our C-band data, mostly within the errors as quoted in Wiegert et al. 2015 with the exception of the large angular size galaxies.  Therefore,  all C-band PB-corrected data (including spectral index maps) on this website have now been corrected to the new PBs as described in EVLA Memo 195.  

Clicking on the optical image of any galaxy will take you to its data release page. Please explore our project web site by clicking on the main navigation bar above.

If you use these data, we would appreciate an appropriate citation. For example, “The CHANG-ES project is described in Irwin et al. 2012, AJ, 144, 43 and details about this first data release are provided by Wiegert et al. 2015, AJ, 150, 81.”

The images above were produced by Jiangtao Li (University of Michigan) for the CHANG-ES consortium using data from the Sloan Digital Sky Survey (http://www.sdss.org) and the Digitized Sky Survey (http://www3.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/dss/). CHANG-ES has been support by the Natural Sciences and Engineering Research Council of Canada.
