First Extragalactic Detection of Thermal Hydroxyl (OH) 18 cm Emission in M31 Reveals Abundant CO-faint Molecular Gas

The Astrophysical Journal
The most abundant interstellar molecule, molecular hydrogen (H _2 ), is practically invisible in cold molecular clouds. Astronomers typically use carbon monoxide (CO) to trace the bulk distribution and mass of H _2 in our galaxy and many others.

The Resolved Structure of a Low-metallicity Photodissociation Region

The Astrophysical Journal
Photodissociation regions (PDRs) are key to understanding the feedback processes that shape interstellar matter in galaxies. One important type of PDR is the interface between H ii regions and molecular clouds, where far-ultraviolet radiation from ...

Absorption and Self-absorption of [C ii] and [O i] Far Infrared Lines toward a Bright Bubble in the Nessie Infrared Dark Cloud

The Astrophysical Journal
Using the upGREAT instrument on board the Stratospheric Observatory for Infrared Astronomy, we imaged [C ii ] 157.74 and [O i ] 63.18 μ m line emission from a bright photodissociation region (PDR) associated with an ionized bubble located in the Nessie ...
