ACME announced the upcoming calendar of remote tutorials and hands-on sessions organized over the next three months by multi-messenger experts from the ACME Joint Centres of Expertise. These sessions aim to provide participants with both introductory knowledge and practical exercises in observational techniques, data analysis, and theoretical software packages and tools in the multi-messenger context. [...]
A new study led by Univ. Würzburg & MPIfR (Luca Ricci) provides unprecedented insights into the central regions of the nearby galaxy NGC 1052. Using high-resolution 43 GHz VLBI observations, the team identified a compact, point-like source within the galaxy’s active nucleus, indicating that NGC 1052 hosts a low-luminosity active galactic nucleus (LLAGN). Remarkably, the [...]
A new study led by MPIfR (Guang-Yao Zhao) demonstrates a major advance in millimeter VLBI: the first single-optical-path frequency-phase-transfer (FPT) observations between 86 GHz and 258 GHz on an 8600 km baseline. Using APEX’s newly commissioned N3AR receiver in dual-band mode and simultaneous observations with the IRAM 30 m telescope — both supported by RadioNet — [...]
Call for Proposals for the East Asian VLBI Network (EAVN)' for the 2026A semester is announced. Please refer to the following EAVN website for more details about the array's specification, available observation modes, and how to submit proposals. https://eavn.kasi.re.kr/ Deadline 2025-11-03 08:00:00 UT
Installation and testing of the ALMA Band 2 receivers, covering 67 to 116 GHz, is currently underway. In anticipation of Band 2 being offered in the near future, the ALMA Band 2 workshop brings together astronomers and ALMA/ARC staff to discuss the new potential for various scientific fields. We plan to have a dedicated session [...]
Astronomers have observed the earliest stages of planet formation around the baby star HOPS-315, 1,300 light-years away. The international team, including scientists from Chalmers University of Technology and Onsala Space Observatory, analyzed chemical signals that reveal the first building blocks of rocky planets. Using data from the James Webb Space Telescope and the ALMA observatory, [...]
Astronomers have observed a rare Einstein Cross with a bright central fifth image, produced by gravitational lensing of the distant galaxy HerS-3 (11.6 billion light-years away). Observations with NOEMA (IRAM, France), ALMA, VLA, and Hubble show that the five-image configuration can only be explained by a massive dark matter halo in the foreground galaxy group. [...]
2026A CALL FOR PROPOSALS - INAF RADIO TELESCOPES -- DEADLINE October 13, 2025 at 12:00 UTC -- The Istituto Nazionale di Astrofisica (INAF) invites scientists to participate in the call for proposals of observing time at the three national radio telescopes: - the 32-m Medicina antenna (Grueff Radio Telescope) - the 32-m Noto antenna - [...]
ESO announces that the 2026 European ALMA School will be hosted by the Allegro ARC node in Leiden, Netherlands, from 26–30 January 2026. The program will cover topics from interferometry basics to advanced data analysis and future ALMA developments, and is open to both beginners and experienced users. The event also includes a tour of [...]
e-MERLIN Invitation for Proposals: Cycle-21 Deadline for Receipt of Proposals: 13:59:59 UT on 23rd October 2025 e-MERLIN requests proposals from the international astronomical community for observations to be made during Cycle-21. Proposals are competitively peer-reviewed under standard STFC rules by the e-MERLIN Time Allocation Committee. Allocation will be made on the basis of scientific merit and technical feasibility alone. Full Details here, see https://www.e-merlin.ac.uk/tools/e-MERLIN_Cycle_21_CfP.pdf for [...]
