High-sensitivity transition-edge-sensed bolometers: improved speed and characterization with AC and DC bias
Logan Foote, Michael D. Audley, Charles +12
We report on efforts to improve the speed of low-G far-infrared transition-edged-sensed bolometers. We use a fabrication process that does not require any dry etch steps to reduce…
Simulation and Measurement of Out-of-Band Resonances for the FDM Readout of a TES Bolometer
Amin Aminaei, Hiroki Akamatsu, Ad Nieuwenhuizen +10
With applications in cosmology, infrared astronomy and CMB survey, frequency-division multiplexing (FDM) proved to be a viable readout for transition-edge sensors (TES). We investi…
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…
Optical performance of prototype horn-coupled TES bolometer arrays for SAFARI
Michael D. Audley, Gert de Lange, Jian-Rong Gao +3
The SAFARI Detector Test Facility is an ultra-low background optical testbed for characterizing ultra-sensitive prototype horn-coupled TES bolmeters for SAFARI, the grating spectro…
The origin of the [C II] emission in the S140 PDRs - new insights from HIFI
C. Dedes, M. Röllig, B. Mookerjea +38
Using Herschel's HIFI instrument we have observed [C II] along a cut through S140 and high-J transitions of CO and HCO+ at two positions on the cut, corresponding to the externally…
CHESS, Chemical Herschel surveys of star forming regions:Peering into the protostellar shock L1157-B1
B. Lefloch, S. Cabrit, C. Codella +74
The outflow driven by the low-mass class 0 protostar L1157 is the prototype of the so-called chemically active outflows. The bright bowshock B1 in the southern outflow lobe is a pr…
Highly abundant HCN in the inner hot envelope of GL 2591: probing the birth of a hot core?
A. M. S. Boonman, R. Stark, F. F. S. van der Tak +5
We present observations of the v2=0 and vibrationally excited v2=1 J=9-8 rotational lines of HCN at 797 GHz toward the deeply embedded massive young stellar object GL 2591, which p…
