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…
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…
