| =========================================== Call for Proposals 2025B (KVN VLBI) Proposal submission deadline: 2025 June 2, 09:00 UT KVN website: http://kvn.kasi.re.kr =========================================== The Korean VLBI Network (KVN) invites scientific proposals for VLBI observations during the 2025B semester from astronomers around the world. Observations of successful proposals will be scheduled between 2025 September 1 and 2026 January 15. Proposals should be submitted via the KVN website (http://kvn.kasi.re.kr) before the deadline of UT 09:00 (KST 18:00) on 2025 June 2. ** Korean VLBI Network (KVN) ** The Korean VLBI Network (KVN) is a dedicated mm-VLBI network, operated by the Korea Astronomy and Space Science Institute (KASI, http://www.kasi.re.kr). Its four 21m radio telescopes are located around South Korea in Seoul, Ulsan, Jeju and Pyeongchang. The baseline length ranges from 133km to 500km. The simultaneous multi-frequency (22/43/86/129 GHz) observing mode in a dual-polarization is available. Data rates of 1, 2, 4, 8 and 16/32 Gbps are supported (please note that for 16/32 Gbps, both time and observation mode may be limited; refer to the KVN Status Report for further details). Total time of 200 hours are planned for this call. If requested in the proposals, the observing schedule can be allocated over a year, until 2026 June 15, but the total observation time will not be increased. Proposers should use the KVN VLBI observing application form and carefully follow the instructions on the KVN website. The scientific and technical justification must be provided within 3 pages. Details of the information and current status of the KVN can be found in the KVN status report on the KVN website (http://kvn.kasi.re.kr). Proposals should be submitted via the KVN website. ** Note on The Pyeongchang telescope ** The KVN Pyeongchang 21 m telescope will participate in the 2025B semester on a shared-risk basis, with availability limited to a select number of receivers. Specifically, the CTR (K/Q/W-band) and 150/230GHz receiver will be operational, though the offered observing time may be adjusted based on installation and maintenance requirements as the development progresses. ** Note on The Yonsei telescope ** The receiver of Yonsei Telescope will be replaced by the CTR. The installation period is expected to be until October, after which 150/230GHz receiver will also be installed. Therefore, the Yonsei Telescope will also operated as a shared-risk base from November in the 2025B semester. ** Note on the EATING VLBI observations ** According to the MoA between INAF (The Istituto Nazionale de Astrofisica), NAOJ (The National Astronomical Observatory of Japan), and KASI up to 30 hours of observing time in VLBI mode are allocated to approved EATING VLBI projects. These projects have to be submitted both to the Italian, Japan and Korean TACs with the standard form selecting "EATING VLBI" mode in the project type. Approved projects will be observed up to 30 hours/semester. Projects exceeding 30 hours will be scheduled together with all other projects according to their relative grades. PIs of these proposals must be associated with INAF or KASI. Detailed information can be found on the website: http://www.radiotelescopes.inaf.it/proposal_main.html.
