The spectacular image spans 190 light-years and is one of a set of long, thin strands of ionized gas that emit radio waves. Installed at the IRAM 30-meter telescope, GISMO observed these curious structures in the shortest wavelength ever. To the scientists' surprise they also detected the most prominent radio filament in the galactic center, known as the Radio Arc, a feature delineating the backbone of a candy cane.

The IRAM program committee convened in Grenoble on October 22 and 23 to evaluate the proposals submitted for the winter 2019/2020 scheduling period. The discussions were organized in 2 panels which were chaired by Amelie Saintonge (University College London, United Kingdom) and Javier Alcolea (OAN, Madrid, Spain). The authors of each proposal will be informed by letter which will include comments issued by the committee if there are any. As usual, the proposals were classified A (accepted), B (backup), and C (rejected).

An international team led by researchers from the CEA Paris-Saclay Astrophysics Department (DAp) has probed for the first time the dust envelopes surrounding stars in formation thanks to the large NOEMA interferometer. Surprisingly, the researchers discovered the presence of large grains whose size grows as one gets closer to the central star. The presence of such large grains, formed only a few 10000 years after the beginning of the gravitational collapse of the molecular cloud from which the star will form, is completely unexpected.

The conference aims to bring together scientists from a wide interdisciplinary community to address recent advances, current challenges and future directions in the field. The conference will feature three days of contributed and invited talks as well as posters on the topic of multi-line observations, analysis and modeling research.

The EHT telescope collaboration has won the 2020 Breakthrough Prize in Fundamental Physics. Hundreds of researchers on the Event Horizon Telescope (EHT) team, including an important number of IRAM scientists will share the Breakthrough prize in fundamental physics for their image of the black hole at the heart of Messier 87, a galaxy 55 million light years from Earth. Congratulations to the entire team, across 60 institutions and 20 countries!

We want to bring to your attention that a new Call for Proposals for IRAM telescopes is now available: A detailed description of the observing capabilities of the 30m telescope and the current status of the NOEMA interferometer are given in two separate documents.

Register now for the 9th IRAM 30-meter Summer School on Millimeter Astronomy that will take place in September, 6-13 in the ski resort of Pradollano, in the Spanish Sierra Nevada, at only 15 minutes driving distance from the IRAM 30-meter telescope.

An extensive observational survey of the Orion B molecular cloud shows why so few stars are forming in its dense gaseous filaments, despite the fact that the cloud shares similarities with other star forming regions.

The IRAM program committee convened in Granada on April 24 and 25 to evaluate the proposals submitted for the summer 2019 scheduling period. The discussions were organized in 2 panels which were chaired by Nathalie Brouillet (Observatoire de Bordeaux) and Javier Alcolea (OAN, Madrid, Spain). The authors of each proposal will be informed by letter which will include comments issued by the committee if there are any. As usual, the proposals were classified A (accepted), B (backup), and C (rejected).

La toute première image d’un trou noir a été obtenue avec l’Event Horizon Telescope (EHT), un réseau de huit radiotélescopes sur 4 continents différents, conçu à cet effet et qui inclut le télescope de 30-mètres de l'IRAM. Cette image dévoile l’ombre du trou noir supermassif situé au cœur de la galaxie M87.

The first ever image of a black hole has been obtained with the Event Horizon Telescope (EHT), a dedicated array of eight radio-antennas over four continents, which includes the IRAM 30-meter telescope. This image reveals the shadow of the supermassive black hole at the center of the M87 galaxy.

Das allererste Bild eines Schwarzen Lochs ist mit dem Event Horizon Telescope (EHT) aufgenommen worden. EHT ist ein zu diesem Zweck gegründeter Verbund aus 8 Radioteleskopen auf 4 verschiedenen Kontinenten, zu dem auch das IRAM 30-Meter-Teleskop gehört. Dieses Bild zeigt den Schatten des supermassiven Schwarzen Lochs im Zentrum der Galaxie M87.

An international team of astronomers led by Dr. Miguel Montargès from KU Leuven has succeeded in reconstructing the 3D geometry of the environment surrounding the red supergiant star μ Cep. The material expelled by the star during its late evolutionary stage provides the building blocks for future planetary and star forming systems. The rate at which the material is expelled is key to understand the further evolution of the star to its next stage, a supernova.

This is the first announcement of the 9th IRAM 30-meter Summer School on Millimeter Astronomy that will take place in September, 6-13 in the ski resort of Pradollano, in the Spanish Sierra Nevada, at only 15 minutes driving distance from the IRAM 30-meter telescope.

With a worldwide array of telescopes that includes the IRAM 30-meter telescope, astronomers have found that the emission from the supermassive black hole Sagittarius A* at the center of our Galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sagittarius A* is pointed almost toward us...
