Telescopes unite in unprecedented observations of famous black hole
In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. Scientists from JIVE contributed to this global effort.
Black holes like to eat, but have a variety of table manners
All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes in a well-studied region of the universe. They publish their findings in two articles in the international journal Astronomy & Astrophysics.
Francisco Colomer elected new Chair of the ERIC Forum
Francisco Colomer, Director of JIVE ERIC, has been elected as the new Chair of the ERIC Forum. With the support of members from the Executive Board, he will be in charge of the strategic management and planning of the ERIC Forum, strengthening its dialogue and relations with key stakeholders such as the European Commission and the ESFRI.
Astronomers Image Magnetic Fields at the Edge of M87’s Black Hole
The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.
Launch of Europe’s largest astronomy network
Two astronomy networks are coming together to form Europe’s largest ground-based astronomy collaborative network, the ORP, supported by €15 million of funding from the H2020 programme. The ORP will provide scientists with access to a wide range of instruments, promote training for young astronomers, and open the way to new discoveries. The project will, among others, facilitate access to the European VLBI Network (EVN) and the Joint Institute for VLBI ERIC (JIVE), develop tools to improve this access, and help develop models for long term sustainability of these research infrastructures.
Italy joins the JIVE ERIC
As of March 12 2021, Italy has become a member of the JIVE European Research Infrastructure Consortium, joining the Netherlands (represented by NWO), the UK (STFC), Sweden (VR), France (CNRS), Spain (IGN) and Latvia (MES). JIVE is also supported by institutes in South Africa (NRF), Germany (MPIfR) and China (NAOC).
Extreme collision of stellar winds occur-ring in the heart of the cosmic serpent
Apep is a stellar system named after the Egyptian god of chaos due to the spiral pattern of dust generated by its two member stars. Now, as-tronomers have looked at Apep’s heart with the highest resolution avai-lable. They have revealed the strongest shock produced by the collision of the extreme winds of the two stars in our Galaxy.
Call for Proposals to the European VLBI Network (deadline February 1st 2021)
Observing proposals are invited for the European VLBI Network (EVN), open to all astronomers. Deadline is Feb 1st 2021, 16h UTC. Astronomers with limited or no VLBI experience are particularly encouraged to apply for observing time.
