Highly responsive Y-Ba-Cu-O thin film THz detectors with picosecond time resolution
P. Thoma, J. Raasch, A. Scheuring +11
High-temperature superconducting YBa2Cu3O7-d (YBCO) thin-film detectors with improved responsivities were developed for fast time-domain measurements in the THz frequency range. YB…
Temperature-dependence of detection efficiency in NbN and TaN SNSPD
Andreas Engel, Kevin Inderbitzin, Andreas Schilling +7
We present systematic measurements of the temperature-dependence of detection efficiencies in TaN and NbN superconducting nanowire single-photon detectors. We have observed a clear…
Break-up of long-range coherence due to phase fluctuations in ultrathin superconducting NbN films
Y. Noat, T. Cren, C. Brun +7
Using scanning tunneling spectroscopy (STS), we address the problem of the superconductor-insulator phase transition (SIT) in homogeneously disordered ultrathin (2-15 nm) films of…
Non-thermal response of YBCO thin films to picosecond THz pulses
P. Probst, A. Semenov, M. Ries +16
The photoresponse of YBa2Cu3O7-d thin film microbridges with thicknesses between 15 and 50 nm was studied in the optical and terahertz frequency range. The voltage transients in re…
[CII] gas in IC 342
M. Röllig, R. Simon, R. Güsten +6
Methods: We used the dual-band receiver GREAT on board the SOFIA airborne telescope to perform observations of the [C II] 158 μm fine-structure line at the postitions of two giant…
Detection of OD towards the low-mass protostar IRAS16293-2422
B. Parise, F. Du, F. -C. Liu +6
Although water is an essential and widespread molecule in star-forming regions, its chemical formation pathways are still not very well constrained. Observing the level of deuteriu…
Probing MHD Shocks with high-J CO observations: W28F
A. Gusdorf, S. Anderl, R. Guesten +5
Context. Observing supernova remnants (SNRs) and modelling the shocks they are associated with is the best way to quantify the energy SNRs re-distribute back into the Interstellar…
[12CII] and [13CII] 158 mum emission from NGC 2024: Large column densities of ionized carbon
U. U. Graf, R. Simon, J. Stutzki +6
Context: We analyze the NGC 2024 HII region and molecular cloud interface using [12CII] and [13CII] observations. Aims: We attempt to gain insight into the physical structure of th…
Dynamics and PDR properties in IC1396A
Yoko Okada, Rolf Güsten, Miguel Angel Requena-Torres +7
We investigate the gas dynamics and the physical properties of photodissociation regions (PDRs) in IC1396A, which is an illuminated bright-rimmed globule with internal structures c…
