Two bolometer arrays for far-infrared and submillimeter astronomy [PDF]

open access: yesSPIE Proceedings, 2004
We describe the development, construction, and testing of two 384 element arrays of ion-implanted semiconducting cryogenic bolometers designed for use in far-infrared and submillimeter cameras. These two dimensional arrays are assembled from a number of 32 element linear arrays of monolithic Pop-Up bolometer Detectors (PUD) developed at NASA/Goddard ...

Mid- Through Far-Infrared Astronomy: The Path to Tomorrow

open access: yes, 2019
The mid- through far-infrared wavelength regime accounts for the second largest component of the spectral energy distribution of the Universe -- below the primordial cosmic background and similar in magnitude to the optical background. The far-infrared peak is due to prolific star formation within galaxies during the early lifetime of the Universe ...

Superconducting Microwave Resonator Arrays for Submillimeter/Far-infrared Imaging [PDF]

open access: yes, 2012
Superconducting microwave resonators have the potential to revolutionize submillimeter and far-infrared astronomy, and with it our understanding of the universe.

Multimode horn antennas for far-infrared astronomy [PDF]

open access: yesThe 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
Multi-mode horns combined with bolometric or incoherent detectors are finding application in astronomical receivers for which partially coherent operation can provide increased throughput and thus sensitivity. This is advantageous when observing faint sources, especially if diffraction limited resolution is not required, or if the horn beam is ...

Probing the Nature of the First Galaxies with JWST and ALMA

open access: yesThe Astrophysical Journal Letters, 2023
By implementing a model of primordial dust emission, we predict dust-continuum fluxes for massive galaxy sources similar to those recently detected by James Webb Space Telescope (JWST) at z ≳ 7.

Astrochemistry With the Orbiting Astronomical Satellite for Investigating Stellar Systems

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Chemistry along the star- and planet-formation sequence regulates how prebiotic building blocks—carriers of the elements CHNOPS—are incorporated into nascent planetesimals and planets.

The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]

open access: yes, 1995
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

Pushing The Limits of Mid-Wave Infrared Detection with Superconducting Nanowire Single-Photon Detectors [PDF]

open access: yesEPJ Web of Conferences
Extending single-photon detection capabilities into the mid- infrared is expected to have far-reaching implications for long-wavelength quantum optics, quantum and free-space communication, astronomy, environmental monitoring, and fundamental molecular ...

Exploring the Magnetic Field Geometry in NGC 891 with SOFIA/HAWC+

open access: yesThe Astronomical Journal, 2023
Stratospheric Observatory For Infrared Astronomy/High-resolution Airborne Wideband Camera-plus 154 μ m Far-Infrared polarimetry observations of the well-studied edge-on galaxy NGC 891 are analyzed and compared to simple disk models with ordered (planar ...

Evidence for the Disruption of a Planetary System During the Formation of the Helix Nebula

open access: yesThe Astronomical Journal, 2022
The persistence of planetary systems after their host stars evolve into their post-main-sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit infrared excess emission and/or spectral absorption lines associated with
