DARK is using the largest ground based telescopes for studying the dark Universe. Access to these telescopes is obtained in international competetion through a peer review procedure where DARK succesfully has obtained observing time.
In particular DARK is using European Southern Observatory's telescopes at Paranal and La Silla in Chile, and the Nordic Optical Telescope at La Palma.
DARK is also using several telescopes on satellites to observe the dark Universe. Access to these telescopes is obtained through peer-reviewed international competition where DARK successfully has obtained observing time on state-of-the-art telescopes. Telescopes orbiting high above the earth can detect cosmic X-rays and gamme-rays that are stopped by the atmosphere, and thus not detectable by ground based telescopes. Also ordinary, visible light is blurred by the atmosphere so a telescope in orbit yields much sharper images than ground based telescopes.
