The February 2023 newsletter of the Atacama Large Aperture Submillimeter Telescope (AtLAST) project has been issued. The ongoing EU-funded design study will deliver, in mid-2024, a full feasibility study that considers the technical, operational, environmental, and scientific challenges of building and operating AtLAST.

The call is open for observing proposals on IRAM telescopes, both the NOEMA interferometer and the 30-meter telescope, for the summer semester 2023. For both observatories, the scheduling period is June 1, 2023 to November 30, 2023. The 30-meter tele- scope will be upgraded in Summer 2023 with observations resuming in early October on a [...]
In a new experiment, Helmut Wiesemeyer from the Max Planck Institute for Radio Astronomy in Bonn/Germany and his colleagues have measured the 18O fraction of the upper mesosphere/lower thermosphere for the first time. They used the GREAT receiver aboard the airborne observatory SOFIA and found that the upper atmosphere has an 18O fraction close to that of [...]
The RadioNet newsletter 01/2023 has just been issued. Read here.
A Call for Proposals (CfP) with detailed information on Cycle 10 is anticipated to be issued in April 2023, and the deadline for proposal submission will be in May 2023. The purpose of this pre-announcement is to highlight aspects of the CfP to assist with early planning. The anticipated proposal submission deadline for Cycle 10 [...]

The MeerKAT team is awarded the Group Award of the Royal Astronomical Society for a series of spectacular observations in radio astronomy, the highlight being the images of the Galactic Centre region and the spectacular radio bubbles. In addition, the MeerKAT team have supported the development of science and technology in Africa and stress-tested technology [...]
While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. Read the ALMA press release here. Image: © ALMA (ESO/NAOJ/NRAO); [...]
