QUIJOTE scientific results - XX. Commissioning and First Results from the Thirty and Forty Gigahertz Instrument (TFGI)
M. Fernández-Torreiro, J. A. Rubiño-Martín, R. T. Génova-Santos +16
We present the commissioning and first results of the Thirty and Forty Gigahertz Instrument (TFGI), which observes the sky at 31 and 41 GHz with angular resolutions of 21' and 18'…
Systematic errors in spectral measurements with the Tenerife Microwave Spectrometer
A. M. Arriero-Lopez, J. A. Rubiño-Martín, F. Cuttaia +2
We present an analytical instrument model of the TMS radiometer, a pseudo-correlation system designed for absolute sky-temperature measurements through a continuous comparison betw…
QUIJOTE-TFGI polarization calibration -- Ground characterization and on-sky validation with Tau A and the Moon
Alessandro Fasano, Mateo Fernández-Torreiro, Guillermo Pascual-Cisneros +6
Our objective is to characterize the QUIJOTE Thirty and Forty GHz instrument (TFGI), calibrate it with a reference calibration signal on the ground, compare our results with on-sky…
The optical system of the Tenerife Microwave Spectrometer: a window for observing the 10-20 GHz sky spectra
P. Alonso-Arias, P. A. Fuerte-Rodriguez, R. J. Hoyland +1
The TMS optical system is based on a decentered dual-reflector system in a Gregorian configuration to observe with an angular resolution of less than . The primary goal of…
