Call for proposals: The 100-m radio telescope of the Max-Planck-Institut für Radioastronomie and the data reduction facilities are available to all qualified scientists. The directors of the institute make observing time available to applicants based on the recommendations of the Program Committee for Effelsberg (PKE), which judges the scientific merit (and technical feasibility) of the observing [...]
Call for proposals: Proposals are invited for observations with the Onsala 20 m diameter telescope in the observing period March-December 2026. Before submitting the proposal, the authors must contact the telescope scientist Henrik Olofsson to arrange with a local collaborator to support the observations. Proposals are to be submitted through the NorthStar system. Deadline: 16 February [...]
The SKA Observatory’s SKA-Mid telescope in South Africa has reached a major milestone by achieving “first fringes”, confirming that the array is operating as an interferometer for the first time. Using two of its 15-metre dishes, SKA-Mid successfully combined signals from a distant radio galaxy around 2.6 billion light years away. This achievement demonstrates that [...]
Astronomers using the European VLBI Network (EVN) have precisely located a repeating fast radio burst, FRB 20190417A, confirming that it originates from a compact, persistent radio source. By combining signals from radio telescopes across Europe and beyond at JIVE, the team achieved milliarcsecond precision, directly linking the brief radio flashes to a constantly emitting source. [...]
The ErUM-IFT-2 project "Information Field Theory for Experiments at Large Research Facilities" has a PhD opening in the field of data-intensive radio astronomy. Methods of information field theory will be used to characterise the properties of radio antennas as used in modern radio interferometers (e. g., MeerKAT, LOFAR, SKA). The goal is to establish accurate [...]
Astronomers have discovered an invisible object with a mass of about one million Suns that doesn’t fit any known cosmic structure. Using gravitational lensing and data from radio telescopes around the world, including the Green Bank Telescope (GBT), the Very Long Baseline Array (VLBA), and the European VLBI Network (EVN)—the team revealed a compact core (likely [...]
SPECTRUM is a Horizon Europe project bringing together leading organisations from Radio Astronomy, High-Energy Physics and e-Infrastructure providers to define a shared vision for a European compute and data continuum. As part of this effort, the draft versions of two main SPECTRUM outputs are now open for feedback: Strategic Research, Innovation and Deployment Agenda (SRIDA) [...]
VLBI proposals for observing at 3mm wavelength (86 GHz) using: the VLBA, APEX, GBT*, EFFELSBERG, IRAM-30m, NOEMA, ONSALA, METSAEHOVI, YEBES and KVN telescopes should be submitted using the NRA Porposa Submission Tool (PST) by 04 FEBRUARY 2026 (UT 22:00)Successful proposals will be considered for scheduling in GMVA Session II 2026 (24-29 September) or in a [...]
The call for observing proposals with the European VLBI Network (EVN) is now open - non-expert teams are especially welcome! Highlights: 4 Gbps recording is becoming the default for continuum projects Regular (non-triggered) e-VLBI projects are very welcome (limited to 2 Gbps)! MeerKAT will be available for EVN observations on a best-effort basis starting session 1/2026. A tied-array beam and the local interferometer data [...]
