Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. The research was led by Maciek Wielgus of the Max Planck Institute for Radio Astronomy in Bonn, Germany.

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)- an international observatory co-operated by the US National Science Foundation's National Radio Astronomy Observatory (NRAO)- have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star.

Nine promising young UvA researchers have received Veni grants from the Dutch Research Council (NWO).

Theoretical physicists have taken a new step in understanding the so-called neutrinoless double-beta decay. This decay in atomic nuclei has never been seen before, but an observation would be an important signal that the standard particle theory is not satisfactory. Theoretician Jordy de Vries of the University of Amsterdam and Nikhef is publishing with colleagues a follow-up to a paper that caused a stir in 2018.

Dark matter might be disappearing and sending its signal - but not very fast - in dwarf satellite galaxies Dark matter is even more elusive than thought before. This is the main message of a new study by a group of scientists that includes Shin'ichiro Ando of the Institute of Physics at the University of Amsterdam.

In a paper that appeared in the journal Physical Review Letters this week, astrophysicists from the University of Amsterdam propose a new way of potentially detecting dark matter. Astrophysicists Thomas Edwards, Marco Chianese and Bradley Kavanagh, from the groups of Samaya Nissanke and Christoph Weniger at the GRAPPA center of excellence, have studied the gravitational waves produced by the merger of a neutron star and a black hole.
