Low-frequency Absorption and Radio Recombination Line Features of the Galactic Center Lobe

The Astrophysical Journal
The Galactic center lobe (GCL) is a ∼1° object located north of the Galactic center. In the mid-infrared, the GCL appears as two 8.0 μ m filaments that roughly define an ellipse.

Circular polarization of interstellar absorption lines at radio frequencies

The Astrophysical Journal, 1985
On etudie la formation d'un rayonnement de raies lineairement et circulairement polarise aux frequences radio lorsque le rayonnement d'une source continue eloignee se propage dans un gaz diffus comme le milieu interstellaire. On a obtenu les equations du transfert radiatif pour les parametres de Stokes (I, Q, U et V)

Algae Protein Creates Sustainable Alternatives for Various Food Matrices: From Function to Nutrition

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
Abstract Protein deficiency and environmental deterioration are pressing and complex issues in traditional agriculture system. Algae, which can grow without the need of land and with minimal water, offer a rich source of protein. Recently, large‐scale algae cultivation and advanced extraction techniques have been developed, positioning algae protein as

A 6 cm Formaldehyde Line Survey toward WISE Point Sources

The Astrophysical Journal Supplement Series
We conducted a 6 cm formaldehyde (H _2 CO) line survey across the northern sky, targeting 3149 high-mass star-forming region candidates selected from the all-sky Wide-field Infrared Survey Explorer (WISE) point-source catalog using the Shanghai TianMa 65

Absorption-Line Probes of Gas and Dust in Galactic Superwinds

, 2000
We discuss moderate resolution spectra of the NaD absorption-line in a sample of 32 far-IR-bright starburst galaxies. In 18 cases, the line is produced primarily by interstellar gas, and in 12 of these it is blueshifted by over 100 km/s relative to the ...

GGR Handbook of Rock and Mineral Analysis Chapter 16 Nano‐Imaging for Advanced X‐Ray Fluorescence and Absorption Spectroscopy Applications

Geostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.
Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

Two New and Remarkable Sightlines through the Galactic Center's Molecular Gas

, 2009
Until now the known sources in the Galactic center with sufficiently smooth spectra and of sufficient brightness to be suitable for high resolution infrared absorption spectroscopy of interstellar gas occupied a narrow range of longitudes, from the ...

The sub‐μm petrography of the observed meteorite fall Winchcombe—A complex array of pristine and altered chondrite components

Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2149-2165, September 2025.
Abstract Samples of observed meteorite falls provide important constraints on alteration histories of Solar System materials. Due to its rapid collection, terrestrial alteration in the observed Mighei‐type (CM) carbonaceous chondrite fall Winchcombe was minimal.

The Distance to the Magellanic Stream: Constraints from Optical Absorption along Stellar Sight Lines

The Astrophysical Journal
The Magellanic Stream is a large tail of neutral and ionized gas originating from tidal and hydrodynamical interactions between the Magellanic Clouds as they orbit the Milky Way (MW).
