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…
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…
A Calibrated Digital Sideband Separating Spectrometer for Radio Astronomy Applications
Ricardo Finger, Patricio Mena, Nicolas Reyes +2
Dual sideband (2SB) receivers are well suited for the spectral observation of complex astronomical signals over a wide frequency range. They are extensively used in radio astronomy…
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…
