Imaging the black hole at the center of our Galaxy
An international team of astronomers will join in April and try for the first time in the history of astronomy, to capture an image of the center of our galaxy, where a giant black hole lies. This worldwide project is called Event Horizon Telescope (EHT); it combines telescopes across four continents from Europe to the South Pole, through Chile and Hawaii. The IRAM 30-meter telescope is one of them...

Beyond the appearances: The anatomy of the Orion Jedi revealed by radio-astronomy
Using the IRAM 30-meter radio-telescope, an international team of astronomers has obtained the most comprehensive radio-survey of the Orion B star-forming region, famous for hosting the iconic Horsehead and Flame nebulae. Through a careful dissection of the cloud into regions of different molecular composition, they shed new light on how the darkest and coldest inner parts give birth to new stars. Following mankind's tradition of associating characters with features on the sky, the radio astronomy view of Orion B seems to show the skeleton of a fighting Star Wars Jedi!

IRAM reveals phosphorus molecular compounds in the solar-type star-forming region L1157
The IRAM 30-meter radiotelescope was used to lead a systematic search for molecules containing phosphorus (P) towards L1157-B1, a shock wave front created by the propagation of a supersonic jet emanating from a solar-type protostar. Several spectral lines of phosphorus mononitride (PN) were detected and, for the first time in a solar-type star-forming region, the lines of phosphorus monoxyde (PO), a molecule of high biological interest.

The most distant cluster of galaxies in the Universe
Through a unique combination of observations made by the largest telescopes in the world, an international collaboration led by researchers from the Astrophysics Department- AIM Laboratory of CEA-IRFU has detected the most distant galaxy cluster ever discovered in the Universe . Back 11.5 billion years in the past of the Universe, the snapshot of this cluster shows 17 galaxies in a strong starburst activity, a period of intense star formation. This is the first time such a structure, captured at the time of its formation, is detected as far away, when the universe was "only" 2.5 billion years.

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...

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.

A multi-year study of the Whirlpool galaxy (M51) has shaken up astronomers’ views of the properties of giant molecular clouds. The new study, which mapped 1,500 such clouds, shows that, instead, they are embedded in a kind of fog of molecular hydrogen much more dense than anyone expected, which permeates the whole of the galactic disc. Pressure exerted by this fog is crucial in determining whether or not new stars will form within the clouds. The study made extensive use of the millimeter telescopes of IRAM, the Institut de Radioastronomie Millimétrique.

A French team of scientists from the Institute of Planetology and of Astrophysics in Grenoble (IPAG, Joseph Fourier University / CNRS) and from the Research Institute in Astrophysics and Planetology (IRAP, University of Toulouse / CNRS) has just announced the presence of formamide in the gas surrounding IRAS 16293-2422, a sun-like forming star in the Rho Ophiuchi nebula. This discovery, published on January 16th, 2013 in the Astrophysical Journal Letter (ApJ 763, L38), could represent an important step in our understanding of the origin of life on Earth.

The discovery of a new interstellar molecule confirms the existence of a petroleum refinery in our galaxy
An international team of scientists has just detected a new interstellar molecule in our galaxy. This molecule, called the propynylidyne ion (C3H+), is part of the hydrocarbon family, which composes one of the major energy sources on Earth, petroleum and natural gas. The discovery of this molecule at the heart of the famous Horsehead Nebula in the Constellation of Orion confirms that this nebula is an active petroleum refinery for the interstellar medium.

A la recherche des molécules complexes et prébiotiques dans les systèmes planétaires en formation
Une équipe internationale vient d’observer pour la première fois la molécule de cyanoacetylène (HC3N) dans des disques protoplanétaires. C’est dans ces disques de gaz et de poussières entourant des jeunes étoiles que les planètes naissent. HC3N est non seulement la molécule la plus complexe détectée à ce jour dans un disque protoplanétaire, mais elle est surtout l’un des précurseurs des molécules organiques complexes, nécessaire à l'apparition de la vie.

Les premiers pas d'une micro-étoile
Une équipe internationale vient de découvrir la toute première étape de la formation d'une naine brune. Plusieurs centaines de ces naines brunes sont aujourd'hui connues mais jusqu'ici jamais il n'avait été possible d'observer le début de la formation de ces micro-étoiles. Grâce à l'interféromètre du Plateau de Bure, les scientifiques ont pu localiser une condensation de gaz et de poussières dont la température est à peine 10 degrés au-dessus du zéro absolu et la masse seulement 2% de celle du Soleil...

Astronomers detect vast amounts of gas and dust around black hole in early universe
Using the IRAM Plateau de Bure array of millimetre-wave telescopes in the French Alps, a team of European astronomers from Germany, the UK and France has discovered a large reservoir of gas and dust in a galaxy that surrounds the most distant supermassive black hole known. Light from the galaxy, called J1120+0641, has taken so long to reach us that the galaxy is seen as it was only 740 million years after the Big Bang, when the universe was only 1/18th of its current age...

Infant galaxies: small and hyperactive
When galaxies are born, do their stars form everywhere at once, or only within a small core region? Recent measurements with the Plateau de Bure Interferometer provide the first concrete evidence that star-forming regions in infant galaxies are indeed small - but also hyperactive, producing stars at astonishingly high rates.
