Measuring Interstellar Carbon Abundance via 158 μm [C ii] Absorption with SOFIA—A Potential Detection and Proof-of-concept for Depletion Studies with Future Far-IR Facilities

The Astronomical Journal
Carbon plays key roles in the interstellar medium (ISM)—as a constituent of dust, as the carrier of the dominant far-infrared (FIR) cooling line, and as a component of various important molecules.

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

, 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 ...

A Confirmed Deficit of Hot and Cold Dust Emission in the Most Luminous Little Red Dots

The Astrophysical Journal Letters
Luminous broad H α emission and red rest-optical spectral energy distributions (SEDs) are the hallmark of compact little red dots (LRDs), implying highly attenuated dusty starbursts and/or obscured active galactic nuclei (AGN).

10 um wavefront spatial filtering: first results with chalcogenide fibers

, 2003
Wavefront cleaning by single-mode fibers has proved to be efficient in optical-infrared interferometry to improve calibration quality. For instance, the FLUOR instrument has demonstrated the capability of fluoride glass single-mode fibers in this respect

Evidence against a simple two-component model for the far-infrared emission from galaxies [PDF]

, 1990
Two of the first Infrared Astronomy Satellite (IRAS) results were that galaxies have a wide range of values for the ratio of 60 micron to 100 micron flux density (0.2 less than or equal to S sub 60/S sub 100 less than or equal to 1.0) and that this ratio

An Analysis of the Complex and Compact Outflow Cavity Carved by HOPS 361-A in NGC 2071 IR

The Astrophysical Journal
We present a combined Stratospheric Observatory for Infrared Astronomy (SOFIA) and two-epoch Hubble Space Telescope (HST) study of the region NGC 2071 IR containing the outflow from the protostar HOPS 361-A (NGC 2071 IRS 1).

SOFIA Polarization Spectrum of Three Star-forming Clouds

The Astrophysical Journal
The dust emission polarization spectrum—how the polarization percentage changes with wavelength—serves as a probe of dust grain properties in star-forming regions.
