Unveiling a Population of Strong Galaxy–Galaxy Lensed, Faint Dusty Star-forming Galaxies

The Astrophysical Journal Letters
The measurements of the number density of galaxy–galaxy strong lenses can be used to put statistical constraints on the foreground mass distributions. Dusty galaxies uncovered in submillimeter surveys are particularly useful in this regard because of the

High resolution spectroscopy in the microwave and far infrared [PDF]

, 1990
High resolution rotational spectroscopy has long been central to remote sensing techniques in atmospheric sciences and astronomy. As such, laboratory measurements must supply the required data to make direct interpretation of data for instruments which ...

Modelling the Spectral Energy Distribution of Compact Luminous Infrared Galaxies: Constraints from High Frequency Radio Data [PDF]

, 2004
We have performed 23 GHz VLA observations of 7 compact, luminous infrared galaxies, selected to have evidence of starburst activity. New and published multi-frequency data are combined to obtain the spectral energy distributions of all 7 galaxies from ...

3D CMZ. I. Central Molecular Zone Overview

The Astrophysical Journal
The Central Molecular Zone (CMZ) is the largest reservoir of dense molecular gas in the Galaxy and is heavily obscured in the optical and near-IR. We present an overview of the far-IR dust continuum, where the molecular clouds are revealed, provided by ...

Far-infrared Emission Lines as Metallicity Diagnostic

The Astrophysical Journal
The chemical abundance of the interstellar medium is a key tracer of galaxy evolution. Optical and ultraviolet emission lines are widely used to derive gas-phase metallicities, but suffer from uncertainties due to possible temperature fluctuations and ...

Monitoring the Dust Emission from R Aqr with SOFIA: Eclipse and Periastron Passage

The Astrophysical Journal
We present infrared (IR) spectra from our monitoring of the symbiotic Mira, R Aquarii, using the Stratospheric Observatory for Infrared Astronomy. New mid-IR photometric and spectroscopic observations using the FORCAST instrument were obtained in 2022 ...

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
