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…
The upGREAT dual frequency heterodyne arrays for SOFIA
C. Risacher, R. Güsten, J. Stutzk +30
We present the performance of the upGREAT heterodyne array receivers on the SOFIA telescope after several years of operations. This instrument is a multi-pixel high resolution (R >…
The upGREAT 1.9 THz multi-pixel high resolution spectrometer for the SOFIA Observatory
C. Risacher, R. Guesten, J. Stutzki +19
We present a new multi-pixel high resolution (R >10^7) spectrometer for the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). The receiver uses 2 x 7-pixel subarrays in…
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…
