Fantastiska 4MOST
4MOST, akronym för “4-meters Multi-Object Spectroscopic Telescope”, kommer snart att ansluta sig till ESO:s växande instrumentfamilj. I denna veckas bild visar 4MOST upp sin mycket speciella förmåga att styra var och en av sina 2436 optiska fibrer individuellt, vilket skapar konturerna av en välbekant logotyp som påminner om en viss superhjältefamilj...
Likt Fantastic Four arbetar alla 4MOST:s fibrer i perfekt synkroni för att få jobbet gjort. Dess superkraft ligger i förmågan att observera många objekt samtidigt, där varje liten fiber kan samla in ljuset från en specifik astronomisk källa. Detta ljus kommer sedan att delas upp i sina beståndsdelar för att erhålla ett spektrum som kan berätta exempelvis om objektets kemiska sammansättning, hastighet eller avstånd. Under en planerad 5-år lång kartläggning förväntas 4MOST fånga spektra av över 25 miljoner olika källor spridda över ett område större än 60 000 fullmånar.
Mängder av mark- och rymdbaserade teleskop tillhandahåller positioner för miljontals astronomiska källor, men de spektra som fångas av 4MOST kommer att vara avgörande för att fullt ut förstå deras fysikaliska egenskaper. 4MOST kommer att hjälpa astronomerna att dechiffrera hur vår galax bildades genom att noggrant studera dess stjärnor. Den kommer också att söka längre bort efter avlägsna galaxer, undersöka hur de utvecklas och studera effekterna av supermassiva svarta hål i deras kärnor. 4MOST:s observationer kan till och med bildra till mer kunskap om den mörka materian som är gömd i hela vårt universum.
Konsortiet som ansvarar för 4MOST leds av Leibniz-Institut für Astrophysik Potsdam (AIP) som för närvarande arbetar tillsammans med ESO-personal för att installera instrumentet på ESO:s Visible and Infrared Survey Telescope for Astronomy (VISTA) vid Paranalobservatoriet i Chile. Vem vet vilka spännande upptäckter som kan hittas i den stora skattkammare av data som instrumentet kommer att tillhandahålla när 4MOST väl är i drift?
