International audienceI present a short history of infrared astronomy, from the first scientific approaches of the `radiant heat' in the seventeenth century to the 1970's, the time when space infrared astronomy was developing very rapidly.

We propose a new amorphous dust emission model based on the soft-potential (SP) model, applicable in the long-wavelength range from the far-infrared to the microwave.

We report the first measurement of polarized thermal dust emission toward the entire infrared dark cloud G11.11−0.12 taken by the polarimeter SOFIA/HAWC+ at 214 μ m. The obtained magnetic fields ( B -fields) from the polarized emission of the early-stage

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Far infrared supplement: Catalog of infrared observations, second edition [PDF]
The Far Infrared Supplement: Catalog of Infrared Observations summarizes all infrared astronomical observations at far infrared wavelengths (5 to 1000 microns) published in the scientific literature from 1965 through 1986.

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

Far-infrared Luminosity Bursts Trace Mass Accretion onto Protostars
Evidence abounds that young stellar objects undergo luminous bursts of intense accretion that are short compared to the time it takes to form a star. It remains unclear how much these events contribute to the main-sequence masses of the stars.

The spectral line energy distribution of carbon monoxide contains information about the physical conditions of the star-forming molecular hydrogen gas; however, the relation to local radiation field properties is poorly constrained.

Surface‐enhanced infrared absorption (SEIRA) and Raman scattering (SERS) are complementary, highly sensitive molecular detection methods. A reusable metamaterial substrate capable of combined SEIRA and SERS is used here for real‐time sensing, tracking interfacial dynamics in an electrochemical reaction and detecting symmetry‐breaking behavior at the ...
