4GREAT -- a four-color receiver for high-resolution airborne terahertz spectroscopy
Carlos A. Durán, Rolf Güsten, Christophe Risacher +13
4GREAT is an extension of the German Receiver for Astronomy at Terahertz frequencies (GREAT) operated aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA). The spect…
First supra-THz Heterodyne Array Receivers for Astronomy with the SOFIA Observatory
Christophe Risacher, Rolf Guesten, Juergen Stutzki +15
We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The Low Frequency Array (LFA) is designed to cover the 1.9-2.5 THz range using 2x7-pixel waveguide-based HE…
HIFI spectroscopy of low-level water transitions in M82
A. Weiss, M. A. Requena-Torres, R. Guesten +23
We present observations of the rotational ortho-water ground transition, the two lowest para-water transitions, and the ground transition of ionised ortho-water in the archetypal s…
