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...

Les jeunes galaxies mangent du froid
Une équipe internationale d’astronomes a réussi à montrer que quelques milliards d’années après le Big Bang, lorsque l’Univers n’avait qu’un tiers de son âge actuel, les galaxies massives formant des étoiles contenaient cinq à dix fois plus de gaz froid que celles d’aujourd’hui. Réalisées grâce à l’interféromètre du Plateau de Bure, ces observations de grandes quantités de matière froide, élément clef dans la formation stellaire, expliquent directement les productions gigantesques d’étoiles à ces époques reculées.

Première localisation de l’eau dans un système planétaire en formation
Pour la première fois, des astronomes ont pu localiser où se trouve l’eau dans les disques en rotation autour d’une jeune étoile, semblable à notre soleil. Ces disques, au sein desquels l’on pense que les planètes se forment, sont constitués de gaz et de poussières. La présente analyse montre, de plus, qu’ils peuvent renfermer jusqu’à cent fois la quantité d’eau contenue dans les océans terrestres. Réalisées avec l’interféromètre du Plateau de Bure, l’un des radio observatoires les plus sensibles au monde, les observations permettent ainsi de dévoiler une partie du mystère de l’origine de l’eau dans les systèmes planétaires...

IRAM scales new heights: At 5000 meters altitude, the institute's equipments capture first fringes at ALMA
On November 5th 2009, first fringes on the high-altitude site were obtained with the band 7 receivers, measuring the continuum emission of a bright quasar, 3C454.3. The result testifies for the high quality and performances of IRAM receivers, which
exhibit noise figures well below the initial ALMA specifications. With its highly recognized expertise, IRAM is one of the major partners in the construction of ALMA, a giant radio observatory in the Chilean desert...

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.

First detection of glycolaldehyde outside the Galactic Center
With the IRAM Plateau de Bure interferometer an international team of scientists has detected for the first time outside the Galactic center the simplest of the monosaccharide sugars: glycolaldehyde. The importance of this organic molecule remains in the fact that it can react with propenal to form ribose, a central constituent of RNA, and is, therefore, directly linked to the origin of life...
