Small Radio Telescope 3m (KRT3)
The Observatory's Kleine Radioteleskop 3m (KRT3) became operational on the roof of the main building in autumn 2019. The instrument is equipped with a parabolic dish of 3 m diameter and with a digital receiver for a wavelength of 21 cm (1420 MHz). With the KRT3 instrument the continuum of bright radio sources and the 21cm line of atomic hydrogen can be observed.
KRT3 is used for an exercise in the advanced practical class (PHY-FP), a module of the physics curriculum, and in the Ferienkurs for high-school students from the municipal region Hamburg, and for public outreach, as on Open Days or the Long Night of the Sciences.
