Unusual Enhancement in He(23S) Airglow Brightness Associated With Interplanetary Magnetic Field Northward Turnings During the 2025 New Year's Day Storm

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Mid-infrared Colors Vary with Galactic Environment: Contrasting Star-forming Disks, Young Centers, and Quiescent Star-formation Deserts

The Astrophysical Journal
We present 50–100 pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming galaxies from the PHANGS-JWST survey.

Characterization of Narrow Band Filters for Infrared Astronomy The Brgamma and H_2 filters

, 1998
We present a characterization of two narrow band filters commonly used in Infrared Astronomy. Our study mainly quantifies the effect of temperature and tilt angle on the central wavelength and width of the transmission bands of such filters.
