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.

IAU Commission Reform: News Update December 2014

In June 2014 the IAU issued an announcement on a plan for reforming the IAU Commissions. This plan includes a call for proposals and the selection of new Commissions. All current Commissions will cease and, following a selection process, new Commissions will begin at the IAU General Assembly in August 2015.

Following the call for proposals, the IAU has received 53 Letters of Intent for Commissions. These include a Letter of Intent for a 'new' Commission for Radio Astronomy.

To indicate the community interest, IAU members are now requested to cast a vote for their preferences and may select up to three Commissions. For further information and links see the Commission 40 News.

The deadline for voting on the Letters of Intent is 31 December 2014.
