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 ...

Astronomy and AstrophysicsContext. Water vapor is the main source of atmospheric opacity for millimeter and sub-millimeter astronomy. Hence, several studies seek to effectively characterize it for site-testing purposes. In this task, reanalysis databases are quickly becoming a popular alternative to on-site measurements due to easy accessibility and the versatility of the data ...

NOEMA complementarity with NIKA2 [PDF]
EPJ Web of Conferences, 2020 IRAM operates two observatories - the 30-meter Telescope on Pico Veleta in Spain and NOEMA, an interferometer of ten 15-meter antennas on Plateau de Bure in France. Both observatories allow to observe at millimeter wavelengths. Here, we aim at discussing

Non-Hermitian Skin Effect in a Non-Hermitian Electrical Circuit
Research, 2021 The conventional bulk-boundary correspondence directly connects the number of topological edge states in a finite system with the topological invariant in the bulk band structure with periodic boundary condition (PBC).

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 ...

Phase and Amplitude Drift Research of Millimeter Wave Band Local Oscillator System [PDF]
Journal of Astronomy and Space Sciences, 2010 In this paper, we developed a local oscillator (LO) system of millimeter wave band receiver for radio astronomy observation. We measured the phase and amplitude drift stability of this LO system.

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 ...
