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.

Paper: SOFIA/HAWC+ Traces the Magnetic Felds in NGC 1068
Lopez-Rodriguez et al., 2020, ApJ, 888, 66.
SOFIA astronomers have measured, for the first time, the magnetic field tracing the star forming regions along the spiral arms of NGC 1068, the nearest grand-design spiral with an active galactic nuclei and a large-scale almost face-on disk.

How do astronomers understand galaxies that are so far away that they may appear as a simple point source, even when observed with the most powerful telescopes? One proven technique is to study local analogues, galaxies that might have similar properties but are close enough to resolve their structures. A study like this was underway when researchers discovered something extraordinary – their observation was 10 times stronger than predicted.

Paper: The Highly Polarized Dusty Emission Core of Cygnus A
Lopez-Rodriguez, Enrique, et al., 2018, ApJL, 861, L23.
Researchers at the University of Texas San Antonio using observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, found that the dust surrounding active, ravenous black holes are much more compact than previously thought.
