Welcome to IAU Commission 40 for Radio Astronomy. Commission 40 is part of IAU Division B for Facilities, Technologies and Data Science.

Commission 40 brings together scientists and engineers who carry out observational and theoretical research in radio astronomy and who develop and operate the ground and space-based radio astronomy facilities and instrumentation that are used to explore the universe at radio wavelengths.

IAU Commission 40 for Radio Astronomy was first established in 1948. In 1997 it became the only Commission in Division X, and in 2012 it became part of the new Division B. As at June 2014 this Commission has approximately 1140 members from 49 countries. 3:30 PM 20/01/2015

IAU Commission Reform: Updated 23 February 2015

Under the IAU plan for reforming the IAU Commissions, all current Commissions will cease and new Commissions will begin at the end of the IAU General Assembly in August 2015.To indicate community interest, IAU members were asked to cast a vote for their preferences based on Letters of Intent for 'new' Commissions.

We thank all those who supported this process and greatly appreciate the strong support shown for the Letter of Intent for a Commission for Radio Astronomy. In total the IAU received votes from 2029 members who voted on over 50 such expressions of interest. The Letter of Intent for Radio Astronomy received the highest number of votes (272).

The IAU will announce the approved Commissions on 20 April 2015. IAU members will be asked to electronically sign up to the Commissions between 30 April and mid-May 2015.
