“How do they get so big? When galaxies collide, their central black holes eventually may merge together too.” “Direct measurements, many made with the help of the Hubble Space Telescope, confirm the presence of more than 100 supermassive black holes,” said Jeremy Schnittman, a theorist at NASA’s Goddard Space Flight Center, in a statement. That’s the point of this video comparison, which shows the size of different types of black holes in comparison to our solar system, scaled according to their shadows. These objects are incredibly dense, though, and it’s hard to picture just how big such an object would be. While a typical black hole weighs up to around 10 times the mass of the sun, supermassive black holes can weigt millions or even billions of times the mass of the sun. da Silva/(Spaceengine) Acknowledgement: M. International Gemini Observatory/NOIRLab/NSF/AURA/J. Illustration of the black hole Sagittarius A* at the center of the Milky Way. Supermassive black holes are found at the center of galaxies (including our own) and generally speaking, the bigger the galaxy, the bigger the black hole. In 2022 the team were awarded 14 million euros from the European Research Council (ERC) for the scientific research with the AMT.This week is black hole week, and NASA is celebrating by sharing some stunning visualizations of black holes, including a frankly disturbing visualization to help you picture just how large a supermassive black hole is. The construction and operation of the telescope will also be supported by a guarantee of 12 million euros from Radboud University. "I am thrilled NWO supports the telescope’s infrastructure with this grant and am looking forward to finally build the telescope with UNAM and our other partners", "Building the AMT telescope is a truly collaborative project" says Marc Klein Wolt, project director and director of the Radboud Radio Lab. The Radboud Radio Lab is responsible for the development of the telescope and the instruments, in collaboration with University of Groningen and ASTRON. We wholeheartedly congratulate them and are looking forward to continued and increased bi- and multi-lateral collaboration on the construction as well as science exploration of the AMT", says Michael Backes from UNAM. "It is with great pleasure that we see our colleagues in the Netherlands receiving also national support for the realisation of our common plan to build the Africa Millimetre Telescope here in Namibia. The millimeter regime of the electromagnetic spectrum is also crucial to study the structure, speed and power of similar plasma flows ejected by neutron stars and black holes." says co-pi Nathalie Degenaar of the University of Amsterdam. This means that we will be able to detect these astrophysical phenomena at earlier stages, which, for instance, will allow us to study the formation and growth of powerful plasma flows. "We expect that for many cosmic explosions, such as gamma-ray bursts, supernovae and fast radio bursts, the emission at millimeter wavelengths will be visible earlier on than at other wavelengths such as optical and radio. We will also be able to extend our studies both in 'colour' as well as black hole mass, via flaring black holes that flash on and off in the sky." The national funding allows the entire Dutch astronomy community to play a pioneering role in bringing the global Event Horizon Telescope to the next level and help us understand the dynamic and violent processes around black holes."Ĭo-PI Sera Markoff at University of Amsterdam: "For the first time we will be able to monitor both the black hole horizon and the enormous plasma jets they eject, allowing us to better understand their launch conditions. Principal researcher, Heino Falcke, at Radboud University: "This telescope will be the first of its kind in Africa and will allow us to peer deep into the heart of our own Milky Way. Oxford University and the University of Namibia (UNAM) are international partners in the proposal. The grant has been awarded to a national consortium of the four NOVA astronomy institutes in the Netherlands, in collaboration with NWO institute ASTRON, the Netherlands Institute for Radio Astronomy, and the Joint Institute for VLBI ERIC (JIVE). The AMT, situated in the southern hemisphere, will have an excellent view of the black hole in the centre of our Milky Way and form a crucial link between telescopes in Europe, South and Latin America and at the South Pole. The EHT collaboration published the first images of two supermassive black holes in 20. This telecope will be built on or close to the Gamsberg in the Khomas highlands and is designed to be able to connect to the Event Horizon Telescope (EHT) network. With the new NWO grant, the Africa Millimetre Telescope (AMT) project is fully funded for construction in Namibia.
