Interstellar absorption lines in the spectrum of zeta Ophiuchi
The Astrophysical Journal, 1975 The far-UV spectrum of Zeta Pup is surveyed as obtained from scans by Copernicus satellite detectors. Equivalent widths are tabulated for 147 lines from 35 different ions or isotopes of 19 elements in the direction of Zeta Pup. In addition, 52 unidentified absorption lines are listed whose narrow widths indicate an interstellar origin.

Small Structures, Volume 7, Issue 6, June 2026.Light‐activated protein‐imprinted PFPA‐functionalized hydrogels crosslink captured proteins and report protein surface accessibility as missing‐peptide patterns readable by standard LC‐MS/MS. Mass spectrometry (MS)‐based structural proteomics can reveal higher‐order structural features in complex biological samples, but many covalent footprinting and ...

The Local Group L-band Survey: Probing Cold Atomic Gas in IC 10 with Neutral Hydrogen Absorption
The Astrophysical JournalWe present the first localized detections of the cold neutral medium (CNM) in IC 10, offering a rare view of dense atomic gas in a low-metallicity ( Z / Z _⊙ ∼ 0.27) dwarf galaxy.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer
Radio Science, Volume 61, Issue 6, June 2026.Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Low-frequency Absorption and Radio Recombination Line Features of the Galactic Center Lobe
The Astrophysical JournalThe 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.

A 6 cm Formaldehyde Line Survey toward WISE Point Sources
The Astrophysical Journal Supplement SeriesWe 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

The Astrophysical Journal, 2001 The three unidentified interstellar lines λλ1368.74, 1369.13, and 1370.87 are here assigned to the CH molecule, including the diffuse interstellar band (DIB) at 1369.13 A. A consistent rotational assignment of the interstellar lines and the 3d-X 2Π laboratory spectrum is presented.

First Observation of CO2 Foreground Absorption toward the Galactic Center with JWST
The Astrophysical JournalCO _2 is an important, stable, and abundant molecule in the Universe, but it is very difficult to detect because it has no observable pure rotational transitions. The unique sensitivity and resolution of the James Webb Space Telescope provide a fresh way
