The European VLBI Network (EVN) continues its successful series of online seminars, highlighting the power of Very Long Baseline Interferometry (VLBI) in modern astronomy. The next seminar will be held on 6 November 2025 at 11:00 CET, presented by Prof. Miguel Pérez-Torres (IAA-CSIC): “New and exciting transient sources unveiled by VLBI.” This talk will explore the [...]
An international team of astronomers has, for the first time, used the NOEMA interferometer to detect the thermal Sunyaev–Zel’dovich (tSZ) effect in the distant galaxy cluster CL J1226.9+3332, nearly 7 billion light-years away (read Muñoz-Echeverría M. et al., 2025). By mapping the tSZ signal at unprecedented resolution, NOEMA revealed that the cluster’s hot gas has a surprisingly [...]
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. [...]
An international team has used the European VLBI Network (EVN) together with e-MERLIN, the Green Bank Telescope, (GBT) and the Very Long Baseline Array (VLBA), to detect a mysterious dark object in a distant galaxy. The discovery, made through the object’s gravitational lensing effect rather than direct light, reveals the lowest-mass object ever identified using [...]
The Committee on Radio Astronomy Frequencies (CRAF) has been admitted as an I-member of the International Special Committee on Radio Interference (CISPR) - a major step toward addressing unintended electromagnetic radiation (UEMR) from satellites. This development marks growing recognition that satellite-generated radio noise poses a serious threat to radio astronomy, which depends on detecting extremely [...]
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
During the week of 22–26 September 2025, the SKA Observatory (SKAO) showcased its scientific and societal impact at G20-related events under South Africa’s presidency. For the first time, SKAO addressed the G20 Research and Innovation Ministerial Meeting, highlighting how its global collaboration is driving discovery, innovation, and socio-economic benefits. The week also saw the first [...]
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 [...]
