Chemical Abundances in a Turbulent Medium -- H, OH, HO, ArH
Shmuel Bialy, David Neufeld, Mark Wolfire +2
Supersonic turbulence results in strong density fluctuations in the interstellar medium (ISM), which have a profound effect on the chemical structure. Particularly useful probes of…
The Structure of Dark Molecular Gas in the Galaxy -- II. Physical State of "CO-Dark" Gas in the Perseus Arm
Michael P. Busch, Ronald J. Allen, Philip D. Engelke +3
We report the results from a new, highly sensitive (mK) survey for thermal OH emission at 1665 and 1667 MHz over a dense, 9 x 9-pixel grid covering a x p…
SOFIA/EXES observations of warm H at high spectral resolution: witnessing para-to-ortho conversion behind a molecular shock wave in HH7
David A. Neufeld, Curtis DeWitt, Pierre Lesaffre +4
Spectrally-resolved observations of three pure rotational lines of H, conducted with the EXES instrument on SOFIA toward the classic bow shock HH7, reveal systematic velocity s…
First astrophysical detection of the helium hydride ion (HeH)
Rolf Güsten, Helmut Wiesemeyer, David Neufeld +7
During the dawn of chemistry when the temperature of the young Universe had fallen below 4000 K, the ions of the light elements produced in Big Bang nucleosynthesis recombine…
