Far-infrared polarimetry from the Stratospheric Observatory for Infrared Astronomy [PDF]
Proceedings of SPIE, 2007 Multi-wavelength imaging polarimetry at far-infrared wavelengths has proven to be an excellent tool for studying the physical properties of dust, molecular clouds, and magnetic fields in the interstellar medium. Although these wavelengths are only observable from airborne or space-based platforms, no first-generation instrument for the Stratospheric ...

Focal Plane Optics In Far-Infrared And Submillimeter Astronomy [PDF]
Optical Engineering, 1986 The construction of airborne observatories, high mountaintop observatories, and space observatories designed especially for infrared and submillimeter astronomy has opened fields of research requiring new optical techniques. A typical far-IR photometric study involves measurement of a continuous spectrum in several passbands between ~30 µm and 1000 µm ...

Mapping the Decline with Redshift of Dusty Star-forming Galaxies Using JWST and SCUBA-2
The Astrophysical Journal, 2023 We use JWST NIRCam observations of the massive lensing cluster field A2744 to develop a red galaxy selection of f _F444W > 1 μ Jy and f _F444W / f _F150W > 3.5 that picks out all nine >4.5 σ Atacama Large Millimeter/submillimeter Array 1.1 or 1.2 mm ...

The Photodissociation and Ionization Fronts in M17-SW Localized with FIFI-LS on Board SOFIA
The Astrophysical Journal, 2023 To understand star formation rates, studying feedback mechanisms that regulate star formation is necessary. The radiation emitted by nascent massive stars play a significant role in feedback by photodissociating and ionizing their parental molecular ...

The Astrophysical Journal, 2023 We explore evolution in the dust-to-gas ratio with density within four well-resolved Local Group galaxies—the LMC, SMC, M31, and M33. We do this using new Herschel maps, which restore extended emission that was missed by previous Herschel reductions ...

A Near-infrared-faint, Far-infrared-luminous Dusty Galaxy at z ∼ 5 in COSMOS-Web
The Astrophysical Journal, 2023 A growing number of far-infrared (FIR) bright sources completely invisible in deep extragalactic optical surveys hint at an elusive population of z > 4 dusty, star-forming galaxies.

An angle-scanned cryogenic Fabry–Pérot interferometer for far-infrared astronomy [PDF]
Review of Scientific Instruments, 2020 The sensitivity of state-of-the-art superconducting far-infrared detectors used in conjunction with cryogenically cooled space telescopes and instrumentation is such that spectroscopic observations are generally limited by photon noise from the astronomical source or by galactic foreground or zodiacal emission within the field-of-view.
