The Greenland Telescope is a 12-meter radio telescope designed for astronomical observations in submillimeter (sub-mm) wavelengths on a high Arctic site. Currently, the telescope is located at Pituffik Space Base (PSB) in the northwestern corner of Greenland and has participated in the observing campaigns of the Event Horizon Telescope [[ii]] (EHT) and the Global Millimeter-wave VLBI Array (GMVA). The first scientific result featuring the GLT revealed a panoramic picture of the black hole and its jet at a 3 mm wavelength. The GLT project was initially a collaboration between the Academia Sinica, Institute of Astronomy and Astrophysics (ASIAA), and the Smithsonian Astrophysical Observatory (SAO). In 2022, the collaboration was expanded to include the Danish partners, represented by the Department of Physics and Astronomy at Aarhus University (AU), Niels Bohr Institute at the University of Copenhagen (NBI), National Space Science Institute at the Technical University of Denmark (DTU), the University of Southern Denmark (SDU). In this talk, I will report on the telescope’s status, scientific objectives, and future plans.
