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.

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

Observing galactic 'blow out'
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.

Questing for black holes in the early Universe
Observations of the infant Universe have shown that the most distant galaxies discovered so far host black holes that are extremely massive, characterized by thousand of billions solar masses. These objects, known with the name of “quasars” are generally discovered through the intense X-ray radiation they emit. The mechanism responsible for the formation of these black holes is still not known. To unveil this mystery...

Journey into the formation of a triple solar system
An international research group from LAB (CNRS / University of Bordeaux), IPAG (CNRS / Université Joseph Fourier Grenoble) and IRAM (CNRS / MPG / IGN), led the most accurate study to date, to observe the distribution of dust and gas in a multiple-star system called GG Tau-A.

First step for NOEMA: MPG President, INSU Director and German Ambassadress inaugurate 1st antenna!
With the official inauguration of the first of six planned NOEMA antennas on 22 September, IRAM is taking a crucial step towards one of the largest Franco-German projects in astronomy: the expansion of the Plateau de Bure observatory in the French Alps into the most powerful and most sensitive millimetre radio telescope in the northern hemisphere. The scientists are hoping that this state of the art observatory will provide answers to questions about our origins and the formation of the universe...

In Memory of Peter Mezger
On July 9, 2014, Prof. Dr.-Ing. Peter Mezger passed away at the age of 85, after a long illness. As a director of the Max-Planck-Institute for Radio Astronomy in Bonn, Peter Mezger was a key figure during the creation and throughout the first 15 years of IRAM. His close relations with the French radio astronomy community allowed the French and German groups to find the mutual understanding and direct exchange necessary for the setup of such a complex co-operation.

Les molécules interstellaires témoins de choix pour l’étude des rayons cosmiques et leur accélération par les supernovae
L'origine du rayonnement cosmique, découvert en 1912 par Victor Hess, reste en grande partie mystérieuse. 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. En particulier...
