Photoelectron Spectroscopy of the Phosphorus Monosulfide (PS) and Phosphorus Monoxide (PO) Radicals

Small Structures, Volume 7, Issue 1, January 2026.
Sketch of the experiment to measure the photo electron spectrum of the PS radical produced in situ with a mixture of PH3, H2S and F atoms. PO and PS radicals are the smallest units of phosphorus oxides and phosphorus sulfides, respectively, two rich families of refractory compounds widely employed in industrial and technological applications. These two

An Investigation into the Selection and Colors of Little Red Dots and Active Galactic Nuclei

The Astrophysical Journal
Recently, a large number of compact sources at z  > 4 with blue UV slopes and extremely red rest-frame optical slopes have been found in James Webb Space Telescope (JWST) extragalactic surveys. As a subsample of these sources, commonly called “little red

The High Plasma Density Observed Along the PJ57 Juno Flyby of Io Implies the Presence of a Dense Atomic Corona

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract On December 2023, the Juno spacecraft made a flyby of Io above the northern hemisphere at a closest approach (CA) altitude of ∼1,500 km (PJ57). The Juno/Waves and Radio‐occultation measurements showed a surprising large electron density ∼28,000 cm−3 near closest approach.

Confirming Near- to Mid-infrared Photometrically Identified Obscured AGNs in the JWST Era

The Astrophysical Journal
We evaluate the underlying assumptions for the identification of active galactic nuclei (AGNs) through near- and mid-infrared photometry and spectral energy distribution (SED) fitting out to z ∼ 3.

Uranus' Long‐Term Thermospheric Cooling Is Unlikely to Be Primarily Driven by the Solar Wind

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Over the last 40 yrs, Uranus' thermospheric temperature has decreased by ∼8 K/yr. Here we show that this is less likely to be driven by solar wind kinetic power than previously thought. We determine that the solar wind kinetic power at Uranus has been increasing since the start of solar cycle 24 in 2009, while Uranus's thermospheric ...

Mid‐infrared Spectroscopy of Protonated Benzonitrile, 2‐Cyanonaphthalene, and 9‐Cyanoanthracene for Astrochemical Consideration

ChemPhysChem, Volume 26, Issue 24, December 16, 2025.
Experimental infrared absorption spectra of three protonated cyano‐substituted PAHs measured by infrared multiple photon dissociation using the free‐electron laser Free‐Electron Laser for Infrared eXperiments are studied. These spectra are compared to an emission spectrum measured by JWST, and the largest measured protonated cyano‐PAH, cyanoanthracene,
