Optimization of Antenna Performance for Global 21-cm Observations and Verification Using Scaled Copies
O. A. Restrepo, F. I. Lucero, G. Chaparro +5
The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although…
The effect of complex dispersion and characteristic impedance on the gain of superconducting traveling-wave kinetic inductance parametric amplifiers
Javier Carrasco, Daniel Valenzuela, Claudio Falcón +2
Superconducting traveling-wave parametric amplifiers are a promising amplification technology suitable for applications in submillimeter astronomy. Their implementation relies on t…
The LSPE-Strip beams
S. Realini, C. Franceschet, F. Villa +13
In this paper we describe the design and characterization of the optical system of LSPE/Strip, a coherent polarimeter array that will observe the microwave sky from the Teide Obser…
Digital compensation of the side-band-rejection ratio in a fully analog 2SB sub-millimeter receiver
R. Rodriguez, R. Finger, F. P. Mena +7
In observational radio astronomy, sideband-separating receivers are preferred, particularly under high atmospheric noise, which is usually the case in the sub-millimeter range. How…
Ultra-pure digital sideband separation at sub-millimeter wavelengths
R. Finger, F. P. Mena, A. Barishev +7
Deep spectral-line surveys in the mm and sub-mm range can detect thousands of lines per band uncovering the rich chemistry of molecular clouds, star forming regions and circumstell…
The ALMA Band 9 receiver - Design, construction, characterization, and first light
A. M. Baryshev, R. Hesper, F. P. Mena +24
We describe the design, construction, and characterization of the Band 9 heterodyne receivers (600-720 GHz) for the Atacama Large Millimeter / submillimeter Array (ALMA). The ALMA…
