Paper: The Magnetic Field Across the Molecular Warped Disk of Centaurus A
Lopez-Rodriguez, E., Nat Astron (2021).

The Stratospheric Observatory for Infrared Astronomy, a joint project of NASA and the German Aerospace Center, DLR, has been used extensively to look many objects in the universe, from black holes to galaxies and even the Moon.

A decade ago, German researcher Heinz Hübers led a team to improve one of SOFIA’s infrared instruments – the German Receiver for Astronomy at Terahertz Frequencies, or GREAT – with a new laser technology. He realized that the upgrade would not only help to study the distant cosmos, it could also be used much closer to home.

What’s fueling the massive ejection of gas and dust out of the Cigar galaxy, otherwise known as Messier 82?

We know that thousands of stars bursting into existence are driving a powerful super-wind that’s blowing matter into intergalactic space. New research shows that magnetic fields are also contributing to the expulsion of material from Messier 82, a well-known example of a starburst galaxy with a distinctive, elongated shape.

Not all appears as it would seem in the Whirlpool galaxy. One of the best-studied spiral galaxies and a delight to amateur astronomers, Messier 51, as it’s officially named, is influenced by powerful, invisible forces.

Paper: [C II] 158 µm self-absorption and optical depth effects
Guevara, C., et al., 2020/04, A&A, 636A, A16.

Photodissociation Regions (PDRs) are zones of the interstellar medium in which Far-UV photons dominate the thermal balance, chemistry, structure, as well as the distribution of the gas and dust. The incident FUV field photodissociates molecules, photoionizes atoms and molecules, and heats the gas and dust.

Paper: Molecular water detected on the sunlit Moon by SOFIA
C.I. Honniball, et al., Nature Astronomy 2020.

Researchers using SOFIA have made the first-ever detection of the water molecule (H2O) on the sunlit surface of the Moon. This discovery refines our understanding of the behavior of water and how volatile elements and compounds interact with airless bodies throughout the Solar System and beyond.

Paper: SOFIA/FORCAST Galactic Center Legacy Survey: Overview
Hankins et al., 2020, ApJ.

SOFIA’s first completed legacy program provides researchers with a vastly improved view of warm dust in the center of the Galaxy, revealing signatures of star formation in exquisite detail.

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.
