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 >…
Spatial distribution of FIR rotationally excited CH+ and OH emission lines in the Orion Bar PDR
A. Parikka, E. Habart, J. Bernard-Salas +7
The abundance of CH+ and OH and excitation are predicted to be enhanced by the presence of vibrationally excited H2 or hot gas (~500-1000 K) in PDRs with high incident FUV radiatio…
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…
The physical state of selected cold clumps
A. Parikka, M. Juvela, V. -M. Pelkonen +2
Context. he study of prestellar cores is essential to understanding the initial stages of star formation. With more cold clumps have been detected than ever before. For…
