A Low Noise NbTiN-Based 850 GHz SIS Receiver for the Caltech Submillimeter Observatory
Author(s): Kooi, J. W.; Kawamura, J.; Chen, J.; Chattopadhyay, G.; Pardo, J. R.; Zmuidzinas, J.; Phillips, T. G.; Bumble, B.; Stern, J.; LeDuc, H. G.
Abstract: We have developed a niobium titanium nitride (NbTiN) based superconductor- insulator-superconductor (SIS) receiver to cover the 350 micron atmospheric window. This frequency band lies entirely above the energy gap of niobium ...

Six Years of Short-Spaced Monitoring of the v=1 and v=2 J=1-0 (28)SiO Maser Emission in Evolved Stars
Author(s): Alcolea, J.; Pardo, J. R.; Bujarrabal, V.; Bachiller, R.; Barcia, A.; Colomer, F.; Gallego, J. D.; Gomez-Gonzalez, J.; delPino, A.; Planesas, P., et al.
Abstract: We present the results from a monitoring of the v=1 and v=2 J=1-0 (28)SiO maser emission in 21 objects, covering all types of known SiO maser emitters: 13 Mira variables, 2 long period semiregulars (SRGs), 3 variable ...

Atmospheric Transmission at Microwaves (ATM): An Improved Model for mm/Submm Applications
Author(s): Pardo, J. R.; Cernicharo, J.; Serabyn, E.
Abstract: We present a model of the longwave atmospheric spectrum which improves in many respects widely used old models such as MPM since it is based on recent broadband measurements and calculations. The model is applicable from 0 ...

Submillimeter FTS Measurements of Atmospheric Opacity above Mauna Kea
Author(s): Serabyn, E.; Weisstein, E. W.; Lis, D. C.; Pardo, J. R.
Abstract: We present accurately calibrated submillimeter atmospheric transmission spectra obtained with an FTS at the Caltech Submillimeter Observatory on Mauna Kea, Hawaii. These measurements cover the 0.9 to 0.3 mm wavelength range, ...
