4MOST Telescope Consortium led by Leibniz Institute for Astrophysics

The European Southern Observatory (ESO) and the Leibniz Institute for Astrophysics Potsdam (AIP) have just signed an agreement for the construction of the 4most telescope. The 4-meter spectroscopic multi-object Telescope (4most) will be installed on the VISTA telescope (Visible and Infrared Survey Telescope for Astronomy) at the Paranal Observatory of the ESO in northern Chile. Over a period of 15 years it will capture about 75 million spectra from objects in the southern sky.

The work by the AIP on 4most is supported by the Federal Ministry of Education and Research (BMBF).

“Today’s signature is a milestone for our institution. This is the first time the AIP as led the consortium for a major project for the ESO.“–Matthias Steinmetz, scientific director of the AIP and Director of the Research Centre “Extragalactic Astrophysics”

The 4most telescope will commence operations in 2022 and contribute to clarifying some of the most pressing questions in astrophysics. 4most will provide important contributions to the study of dynamical and chemical evolution of the Milky Way, measured active galaxies and galaxy clusters and can verify models of accelerated expanding universe.

“There are exciting years ahead of us. With 4most we will be able to address numerous astronomical questions, for example, the history and future of our Milky Way or the development of massive black holes in the centre of galaxies.”–Roelof de Jong, principal investigator of 4most project.

4most will simultaneously collect spectra from about 2,400 objects which are spread over an area of four square degrees in the southern sky. Within five years, 25 million spectra will be recorded in an area of about 17,000 square degrees. This represents more than 40 percent of the entire sky. With a planned duration of 15 years 4most will capture about 75 million spectra for astronomical research.

The 4most consortium consists of 15 institutions from Germany, Britain, France, Sweden, Switzerland, Australia and the Netherlands. They are led by Leibniz Institute for Astrophysics Potsdam (AIP).
