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 seven 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. [...]

A distant galaxy cluster merger
A team of scientists using the Goddard-IRAM Superconducting 2-Millimeter Observer (GISMO) on the IRAM 30 meter telescope selected one spectacular cluster previously found by Planck to image at 30 times higher resolution than Planck’s original detection. The cluster they observed, called PLCK G147.3-16.6, was known from early X-ray follow-up observations with the ESA’s XMM-Newton telescope to be a merger of two smaller clusters. To the surprise of the scientists...

Galactic ‘hailstorm’ in the early Universe
Astronomers have been able to peer back to the young Universe to determine how quasars – powered by supermassive black holes with the mass of a billion suns – form and shape the evolution of galaxies.

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...
