APEX Celebrates Ten Years Exploring the Cold Universe

Atacama Pathfinder Experiment in Chile looks forward to further success at the cutting edge of astronomy

10 February 2016

A celebration was held at the APEX [1] base station in Sequitor, San Pedro de Atacama, to mark ten years of astronomical research with the APEX telescope, which resides on Chile’s Chajnantor Plateau, 5100 metres above sea level.

From there, the telescope observes the sky in submillimetre wavelengths, giving astronomers access to the coldest regions of the Universe, which cannot be seen in visible light. As it looks forward to further discoveries at the forefront of observational astronomy, the APEX 12-metre telescope has already made significant contributions across a variety of astronomical fields, including the discovery of new interstellar molecules and deep imaging of the submillimetre sky, leading to new insights into star formation in the Milky Way and distant starburst galaxies in the early Universe.

The Sequitor base station was chosen for the celebration, as it is at the more comfortable altitude of 2500 metres above sea level. But participants did have an opportunity to visit the telescope site itself, as our pictures show. A number of special guests were present for the occasion, including the German ambassador to Chile, Rolf Schulze, the president of the Max Planck Society, Martin Stratmann, and the Director General of ESO, Tim de Zeeuw. For the other partners in the APEX collaboration, Karl Menten and project manager Rolf Güsten from the Max Planck Institute for Radio Astronomy (MPIfR) and John Conway from Sweden’s Onsala Space Observatory (OSO) also attended the event.

Notes

[1] Over the last ten years, about 2000 scientists have used data obtained with APEX for science projects, resulting in more than 500 publications. Major APEX results include the discovery of five new molecules in the interstellar medium and also large surveys including ATLASGAL (APEX Telescope Large Area Survey of the Galaxy), and LESS (LABOCA Survey of the Extended Chandra Deep Field South).  Both have used the Large APEX Bolometer Camera (LABOCA) to measure the star formation activity in the Milky Way and at early epochs of the Universe. The APEX telescope makes use of its access to the southern sky, in particular the central parts of the Milky Way and the Magellanic Clouds.

Further Information

APEX is a collaboration between the Max Planck Institute for Radio Astronomy (MPIfR), the Onsala Space Observatory (OSO) and ESO. Operation of APEX at Chajnantor is carried out by ESO.
