Technology for Submillimeter Astronomy [PDF]
IEEE MTT-S International Microwave Symposium Digest IEEE MTT-S International Microwave Symposium, 2007 Despite about three decades of progress, the field of submillimeter astronomy remains quite challenging, because the detection technology is still under development and the transmission of the atmosphere is poor. The latter problem has been overcome by constructing submillimeter telescopes at excellent sites, first on Mauna Kea and later in Chile and ...

The fastscanning observing technique for millimeter and submillimeter astronomy [PDF]
Astronomy and Astrophysics, 2001 Fastscanning is a new observing technique for millimeter and submillimeter astronomy from ground based telescopes. The atmosphere is eliminated by taking advantage of detector arrays. Instead of wobbling the secondary mirror with a fixed frequency of a few Hz to filter the atmospheric contribution, we sample the detector outputs at a much higher rate ...

A Low-Insertion Loss Cryogenic Edge-Mode Isolator With 18 GHz Bandwidth
IEEE Journal of Microwaves, 2023 Cryogenic isolators play an important role in low-noise receiver systems widely employed in millimeter and submillimeter telescopes. To enable a significantly wider Intermediate Frequency (IF) bandwidth, there is strong demand for a wideband, low-loss ...

2 mm Observations and the Search for High-redshift Dusty Star-forming Galaxies
The Astrophysical Journal, 2023 Finding high-redshift ( z ≫ 4) dusty star-forming galaxies is extremely challenging. It has recently been suggested that millimeter selections may be the best approach since the negative K-correction makes galaxies at a given far-infrared luminosity ...

Lack of Correlations between Cold Molecular Gas and AGN Properties in Type 1 AGNs at z ≲ 0.5
The Astrophysical Journal, 2023 We present new NOrthern Extended Millimeter Array (NOEMA) observations of the CO(2–1) emission in eight of the brightest Palomar-Green quasars at z ≲ 0.5 to investigate the role of active galactic nucleus (AGN) feedback in luminous quasars detected at ...

Uranus’s and Neptune’s Stratospheric Water Abundance and Vertical Profile from Herschel-HIFI
The Planetary Science Journal, 2022 Here we present new constraints on Uranus’s and Neptune’s externally sourced stratospheric water abundance using disk-averaged observations of the 557 GHz emission line from Herschel’s Heterodyne Instrument for the Far-Infrared.
