Observation and calibration strategies for large-scale multi-beam velocity-resolved mapping of the [CII] emission in the Orion molecular cloud
R. Higgins, S. Kabanovic, C. Pabst +15
Context. The [CII] 158micron far-infrared fine-structure line is one of the dominant cooling lines of the star-forming interstellar medium (ISM). Hence [CII] emission originates in…
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…
An overview of the planned CCAT software system
Tim Jenness, Martin C. Shepherd, Reinhold Schaaf +7
CCAT will be a 25m diameter sub-millimeter telescope capable of operating in the 0.2 to 2.1mm wavelength range. It will be located at an altitude of 5600m on Cerro Chajnantor in no…
The effect of sideband ratio on line intensity for Herschel/HIFI
Ronan Higgins, David Teyssier, Colin Borys +8
The Heterodyne Instrument for the Far Infrared (HIFI) on board the Herschel Space Observatory is composed of a set of fourteen double sideband mixers. We discuss the general proble…
