KVN and VERA Array (KaVA)

Call for Proposal (CfP)

We invite proposals for the open use observations of the KaVA, a joint VLBI array of the KVN (Korean VLBI Network) and the VERA (VLBI exploration of Radio Astrometry). The joint array consists of three 21-m KVN telescopes and four 20-m VERA telescopes, with baseline lengths ranging from 300 km to 2300 km.


This open use call will be based on risk-share, and provide VLBI observations at 22GHz and 43GHz for astronomers in the world. We support astronomers in the preparation of proposals, scheduling, and data analysis. If proposers are not familiar with KaVA, they are recommended to include at least one collaborator from VERA or KVN. If it is difficult to find collaborators from VERA or KVN, please consult us to find one. The contact address for the support is kavaprop (at-mark) kasi.re.kr.

Observations will be conducted with single polarization (LCP) and 1-Gbps data rate. The total available observation time is up to 250 hours and the observations will be scheduled between 15th January 2018 and 15th June 2018. The maximum observing time per proposal is limited to 100 hours. If requested in the proposals, the observation time can be allocated over a year, until 15th January 2019, for this call. But the observation time will be still limited to 100 hours.

The deadline of submission is at

08:00 UTC on 1st November, 2018, 08:00 UT.
