e-MERLIN telescope at Jodrell Bank: First radio detection of Type Ia supernova explosion

e-MERLIN telescope at Jodrell Bank: First radio detection of Type Ia supernova explosion

Thanks to the e-MERLIN telescope network based at Jodrell Bank, The University of Manchester, astronomers have found the origin of a Type Ia supernova explosion using radio emissions.

The first radio detection of a Type Ia supernova, confirms that the SN 2020eyj came from a binary star system composed of a white dwarf and a solar-type star.

The results were published in the journal Nature with the title A radio-detected type Ia supernova with helium-rich circumstellar material (DOI: https://doi.org/10.1038/s41586-023-05916-w, published 17 May 2023).

How the black hole in M87 launches a jet

How the black hole in M87 launches a jet

An international team of scientists with participation of the Max Planck Institute for Radio Astronomy has used new millimetre-wavelength observations to image for the first time the link between the ring-like structure that reveals the matter falling into the central black hole and the powerful relativistic jet in the prominent radio galaxy Messier 87 (M87). These images show the origin of the jet and the accretion flow near the central supermassive black hole. The new observations were obtained with the Global Millimetre VLBI Array (GMVA), complemented by the phased Atacama Large Millimetre/submillimetre Array (ALMA) and the Greenland Telescope (GLT). The addition of these two observatories has greatly enhanced the imaging capabilities of the GMVA. Read more.

IAU Executive Committee Working Group for Dark & Quiet Sky Protection

IAU Executive Committee Working Group for Dark & Quiet Sky Protection

The IAU Executive Committee Working Group for Dark and Quiet Sky Protection has published its 2022 Annual Report.

The IAU has as a priority goal the reduction and prevention of artificial sky glow and radio-frequency interference. The IAU Executive Committee Working Group for Dark & Quiet Sky Protection focuses on the protection of the sky for astronomical observations at all wavelengths and includes collaborative efforts with the IAU-UNESCO initiative of World Heritage astronomical sites.

SKAO Signs Hosting Agreements With Australia And South Africa


• In early May, the SKAO held a joint conference with the US’ National Radio Astronomy Observatory (NRAO) to discuss synergies between the SKA telescopes and ngVLA.

The hybrid event, held in Vancouver, Canada, attracted close to 300 participants.

• The SKAO also issued a statement in response to the G7 Science and Technology Ministers’ Communiqué which references the issue of dark and quiet skies for the time. The SKAO, a co-host of the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (IAU CPS), worked with several societies and organisations to highlight the importance of the issue to ministers ahead of the meeting.

EC: Horizon Europe Strategic Plan published

The Horizon Europe Strategic Plan 2025-2027 analysis is now public.

The analysis is the result of a co-creation process between the internal services of the EC and the EU Member States and will serve as common analytical foundation for development of the next Horizon Europe Strategic Plan and as support for the EC to prepare for the last two years of the R&I Framework Programme (2025-2027).

EC restrictions concerning Hungarian project partners

From 16 December 2022 onwards, no new legal obligations concerning EU funding may be entered into with certain Hungarian institutions - Council Implementing Decision (2022/2506)

Furthermore, as of 16 December 2022, no other new commitments involving EU funds may be entered into with these Hungarian entities in the context of Horizon projects. This concerns subcontracting, but also, among other things, the purchase of goods, works and services and personnel costs if personnel is seconded from the Hungarian institution to a beneficiary/affiliated entity.

Read here the FAQs on restrictions for EU projects in which Hungarian partners are or are to become project participants or suppliers.

European Commission seeks experts for the interim evaluation of Horizon Europe

European ALMA Regional Centre

The European ALMA Regional Centre (ARC) provides the interface between the ALMA project and the European science community. The ARC is staffed by scientists with expertise in radio astronomy and interferometry and it supports its users throughout the lifetime of a project, from proposal preparation to data analysis. Users that want to visit an ARC node for a face-to-face visit can apply for funding through the ORP project. 

The Westerbork Apertif Long Term Archive (ALTA) offers to the world-wide astronomical community free virtual access to data and scientific products produced from all sky surveys of the Northern sky that will be conducted with the new Apertif frontend of the Westerbork Synthesis Radio Telescope (WSRT), as well as tools to query, further exploit and perform data mining of these products adaptable to diverse research goals. The access/funding offered through the ORP project.

LOFAR Long Term Archive (LTA) is a long-established archive and access facility supporting the international LOFAR telescope. It is currently the largest radio astronomical archive in the world already exceeding 45 PB from LOFAR’s past 10 years of operations. The LTA provides a central and key resource for all observed LOFAR astronomical science programs where the data become public within 12 months of first creation. The access/funding is offered through the ORP project.
