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 ...

Integrated heterodyne array receivers for submillimeter astronomy [PDF]
SPIE Proceedings, 2003 The advent of large format (~100 pixel) spectroscopic imaging cameras at submillimeter wavelengths would fundamentally change the way in which astronomy is performed in this important wavelength regime. While the possibility of such instruments has been discussed for more than two decades, only recently have advances in mixer technology, device ...

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 ...
