Mapping Water on the Lunar Surface

By Bill Reach and Joan Schmelz

For the first time, SOFIA has made a detailed map of water on the surface of the Moon. Comparison with the lunar landscape shows that the water emission is strongest on the shady sides of deep craters and high mountains. Researchers used observations taken on 2022 February 17 as part of a SOFIA Legacy project intended to explore how water is distributed across the lunar surface.

Magnetically-Driven Flows in NGC 1097

By Enrique Lopez-Rodriguez and Joan Schmelz

Paper: Extragalactic Magnetism with SOFIA (Legacy Program) - II: A Magnetically Driven Flow in the Starburst Ring of NGC 1097
Lopez-Rodriguez, Enrique, et al., 2021/12, ApJ, 923, 150.

Magnetically-driven flows feed the super massive blackhole at the center of NGC 1097. SOFIA investigated this long-standing problem of the large-scale transfer of matter from the body of the host galaxy to the active nucleus.

Evidence of [CII] Shocked Emission in NGC 7479

By Dario Fadda and Joan Schmelz

Paper: [C II] and CO Emission along the Bar and Counter-arms of NGC 7479
Fadda, Dario, et al., 2021/03, ApJ, 909, 204.

SOFIA observations of the barred spiral galaxy, NGC 7479, were able to separate shock-enhanced ionized carbon [CII] emission from that associated with star formation, reminding us that it is important to consider multiple mechanisms when studying the [CII] emission in galaxies with active nuclei.
