Holographic surface measurement system for the Fred Young Submillimeter Telescope
Xiaodong Ren, Pablo Astudillo, Urs U. Graf +6
We describe a system being developed for measuring the shapes of the mirrors of the Fred Young Submillimeter Telescope (FYST), now under construction for the CCAT Observatory. "Hol…
4GREAT -- a four-color receiver for high-resolution airborne terahertz spectroscopy
Carlos A. Durán, Rolf Güsten, Christophe Risacher +13
4GREAT is an extension of the German Receiver for Astronomy at Terahertz frequencies (GREAT) operated aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA). The spect…
The large scale polarization explorer (LSPE) for CMB measurements: performance forecast
The LSPE collaboration, G. Addamo, P. A. R. Ade +102
[Abridged] The measurement of the polarization of the Cosmic Microwave Background radiation is one of the current frontiers in cosmology. In particular, the detection of the primor…
Progress report on the Large Scale Polarization Explorer
L. Lamagna, G. Addamo, P. A. R. Ade +96
The Large Scale Polarization Explorer (LSPE) is a cosmology program for the measurement of large scale curl-like features (B-modes) in the polarization of the Cosmic Microwave Back…
Wideband 67-116 GHz receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, V. Belitsky +43
ALMA has been operating since 2011, but has not yet been populated with the full suite of intended frequency bands. In particular, ALMA Band 2 (67-90 GHz) is the final band in the…
The upGREAT dual frequency heterodyne arrays for SOFIA
C. Risacher, R. Güsten, J. Stutzk +30
We present the performance of the upGREAT heterodyne array receivers on the SOFIA telescope after several years of operations. This instrument is a multi-pixel high resolution (R >…
The STRIP instrument of the Large Scale Polarization Explorer: microwave eyes to map the Galactic polarized foregrounds
C. Franceschet, S. Realini, A. Mennella +48
In this paper we discuss the latest developments of the STRIP instrument of the "Large Scale Polarization Explorer" (LSPE) experiment. LSPE is a novel project that combines ground-…
Wideband 67-116 GHz cryogenic receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, L. Testi +25
The Atacama Large Millimeter/sub-millimeter Array (ALMA) is already revolutionising our understanding of the Universe. However, ALMA is not yet equipped with all of its originally…
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…
The Atacama Large Millimeter/submillimeter Array (ALMA) Band-1 Receiver
Yau De Huang, Oscar Morata, Patrick Michel Koch +29
The Atacama Large Millimeter/submillimeter Array(ALMA) Band 1 receiver covers the 35-50 GHz frequency band. Development of prototype receivers, including the key components and sub…
The upGREAT 1.9 THz multi-pixel high resolution spectrometer for the SOFIA Observatory
C. Risacher, R. Guesten, J. Stutzki +19
We present a new multi-pixel high resolution (R >10^7) spectrometer for the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). The receiver uses 2 x 7-pixel subarrays in…
First supra-THz Heterodyne Array Receivers for Astronomy with the SOFIA Observatory
Christophe Risacher, Rolf Guesten, Juergen Stutzki +15
We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The Low Frequency Array (LFA) is designed to cover the 1.9-2.5 THz range using 2x7-pixel waveguide-based HE…
