IRAM
IRAM is an international research institute for radio astronomy. Its overall objective is to explore the universe and to study its origins and evolution.

IRAM was founded in 1979 and its headquarters are located in Grenoble, France. With a staff of more than 120 scientists, engineers, technicians and administrative personnel, IRAM develops and maintains two observatories: the 30-meter telescope located on the Pico Veleta near Granada, Spain, and the NOEMA interferometer (currently an array of ten 15-meter telescopes) in the French Alps. Both instruments are prime facilities for radio astronomy and among the most powerful observatories today operating at millimetre wavelengths. [...]

First detection of a radioactive molecule in interstellar space
An international team of astronomers, based in the US, Poland, Germany, Australia and France has made the first clear detection of a radioactive molecule in interstellar space: the isotopologue of aluminum monofluoride, 26AlF. Recent data – obtained with NOEMA, ALMA, IRAM 30m and APEX – suggest that this radioactive molecule was ejected into space by the collision of two stars, an extremely rare cosmic event that was witnessed on Earth as a nova, in the year 1670.

The most distant black hole in the cosmos
Astronomers have discovered the most distant quasar known, which is so far from us that its light has taken more than 13 billion years to reach us. We see this quasar as it was a mere 690 million years after the Big Bang, and its light carries valuable information about the early history of the universe...

IRAM closes in on NOEMA's full potential: PolyFiX and the Nine Antenna Array
We are very pleased to announce the successful implementation of the wideband high-performance correlator PolyFiX in concert with the nine antenna array. The commissioning of PolyFIX represents the next crucial milestone in the quest for ever higher sensitivity. The very first observations of a line survey at high-redshift in the 3mm-band are given below as a foretaste of NOEMA's full potential that is now within grasp.

Une première image du trou noir au centre de notre galaxie?
C’est grâce à un réseau mondial de radiotélescopes qu’une équipe internationale d’astronomes essaiera en avril, une première dans l’histoire de l’astronomie, d’obtenir une image du centre de notre galaxie, là où se trouve un trou noir géant. Ce projet mondial s’appelle Event Horizon Telescope (EHT) et associe des télescopes du monde entier – de l’Europe jusqu’au pôle sud, en passant par le Chili et Hawaii. Le télescope de 30-mètres de l'IRAM est la seule station d'observation en Europe...

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...
