Rare Sighting of Luminous Jet Spewed by Supermassive Black Hole
What happens when a dying star flies too close to a supermassive black hole? In some extremely rare cases, the supermassive black hole launches “relativistic jets”—beams of matter traveling close to the speed of light—after destroying a star. Using NOEMA and several other observatories, astronomers just got the chance to observe one of these rare cosmic events.

Les astronomes révèlent la première image du trou noir au cœur de notre galaxie
Des astronomes ont dévoilé la première image du trou noir supermassif situé au centre de notre propre galaxie, la Voie lactée. Ce résultat apporte la preuve irréfutable que l'objet est bien un trou noir et fournit des indices précieux sur le fonctionnement de ces géants, dont on pense qu'ils se trouvent au centre de la plupart des galaxies. L'image a été produite par une équipe de recherche mondiale appelée Event Horizon Telescope (EHT) Collaboration, à partir des observations d'un réseau mondial de radiotélescopes dont le télescope de 30 mètres. Les résultats sont publiés dans The Astrophysical Journal Letters.

Astronomers reveal first image of the black hole at the heart of our galaxy
Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes including the IRAM 30-meter telescope.

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.

A growing stellar system directly fed by the mother cloud
For the first time, astronomers have observed a conveyor belt from the outskirts of a star-forming dense cloud directly depositing material near a pair of young forming stars. Scientists at the German Max Planck Institute for Extraterrestrial Physics (MPE) and the French Institut de Radioastonomie Millimétrique (IRAM) found that gas motions in the conveyor belt, dubbed a 'streamer', mainly obey the gravitational pull of the innermost part of the core, near the protostar pair.

Tiny globules around young and massive stars: what do they hide?
A unique combination of the IRAM 30-meter telescope and SOFIA images of the Orion Nebula reveals how the winds and UV radiation from young massive stars eat up their natal molecular cloud. The detection of small molecular globules inside the disrupted material can be explained as a result of the unavoidable cloud destruction process. These tiny globules, however, hide unexpected surprises.

A revised timeline for planetary formation? Sounding the cosmic dust around young stars
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.

IRAM reveals a large reservoir of organic material in the starless core L1544
Placed in the Taurus star forming region, at about 450 light-years from Earth, L1544 is the prototype of prestellar cores, the cold gas condensations on the verge of collapsing to form new stars. An unbiased frequency survey of this dense core has been carried out with the IRAM 30-m radiotelescope, as a part of the Large Program ASAI (Astrochemical Surveys at IRAM; Lefloch, Bachiller et al. 2015), and has recently been used by Vastel et al. (2014, 2015) to provide the full census of oxygen bearing complex organic molecules (COMs) in its central region. As an example, Figure 1 shows the richness of the spectrum in the frequency range from 81 to 89 GHz, together with the identification of the most prominent lines.

Is the black hole in NGC 1277 really obese?
It is well known that each galaxy hosts in its nucleus a super-massive black hole, of mass equal to 0.2-1% of its bulge mass. Recently a few exceptions of over-massive black holes might have been discovered, although this is still under debate. In the lenticular galaxy NGC 1277 in the Perseus cluster, the largest black hole ever has been claimed, through stellar kinematics measurements, to be about 50% of its bulge mass! Some astronomers have contested this value...

For the first time, an international team of astronomers has revealed the dramatic ‘blow out’ phase of galactic evolution. The astronomers discovered dense gas being blasted out of a compact galaxy (called SDSS J0905+57) at speeds of up to two million miles per hour. The gas is being driven to distances of tens of thousands of light years by the intense pressure exerted on it by the radiation of stars that are forming rapidly at the galaxy’s centre.

Une méthode d’observation originale pour ce domaine de l’astrophysique, a été utilisée par une équipe de chercheurs. À l'aide du radiotélescope de 30m de l'IRAM, ils ont détecté, dans les nuages moléculaires voisins irradiés par la supernova W28, la signature laissée par des particules de relativement basse énergie (500 MeV) produites dans le choc associé à l'explosion de la supernova.

L’étude, au cours de laquelle 1500 nuages moléculaires ont été observés, montre que ces nuages moléculaires se trouvent en fait entourés d'une brume d’hydrogène moléculaire beaucoup plus dense que supposait auparavant. La pression exercée par cette brume se révèle être l’élément déterminant pour la formation stellaire au sein des nuages moléculaires.
