SOFIA/EXES observations of warm H2 at high spectral resolution: II. IC443C, NGC2071, and 3C391

David A. Neufeld, Curtis DeWitt, Pierre Lesaffre +4

Using the EXES instrument on SOFIA, we have obtained velocity-resolved spectra of several pure rotational lines of H2 toward shocked molecular gas within three Galactic sources: th…

JWST/MIRI detection of suprathermal OH rotational emissions: probing the dissociation of the water by Lyman alpha photons near the protostar HOPS 370

David A. Neufeld, P. Manoj, Himanshu Tyagi +22

Using the MIRI/MRS spectrometer on JWST, we have detected pure rotational, suprathermal OH emissions from the vicinity of the intermediate-mass protostar HOPS 370 (OMC2/FIR3). Thes…

JWST detection of extremely excited outflowing CO and H2O in VV 114 E SW: a possible rapidly accreting IMBH

Eduardo González-Alfonso, Ismael García-Bernete, Miguel Pereira-Santaella +3

Mid-infrared (mid-IR) gas-phase molecular bands are powerful diagnostics of the warm interstellar medium. We report the James Webb Space Telescope detection of the CO v=1-0 (4.4-5.…

[CII] absorption and emission in the diffuse interstellar medium across the Galactic Plane

M. Gerin, M. Ruaud, J. R. Goicoechea +10

Ionized carbon is the main gas-phase reservoir of carbon in the neutral diffuse interstellar medium and its 158 micron fine structure transition [CII] is the most important cooling…

Herschel/HIFI observations of [CII] and [13CII] in PDRs

V. Ossenkopf, M. Röllig, D. A. Neufeld +5

Recently, we introduced detailed isotopic chemistry into the KOSMA-tau model for photon-dominated regions (PDRs) to give theoretical predictions for the abundance of the carbon iso…

Herschel/HIFI observations of red supergiants and yellow hypergiants: I. Molecular inventory

D. Teyssier, G. Quintana-Lacaci, A. P. Marston +17

Red supergiant stars (RSGs) and yellow hypergiant stars (YHGs) are believed to be the high-mass counterparts of stars in the AGB and early post-AGB phases. We study the mass-loss i…

Herschel observations of EXtra-Ordinary Sources (HEXOS): Observations of H2O and its isotopologues towards Orion KL

G. J. Melnick, V. Tolls, D. A. Neufeld +49

We report the detection of more than 48 velocity-resolved ground rotational state transitions of H2(16)O, H2(18)O, and H2(17)O - most for the first time - in both emission and abso…

HIFI observations of warm gas in DR21: Shock versus radiative heating

V. Ossenkopf, M. Röllig, R. Simon +35

The molecular gas in the DR21 massive star formation region is known to be affected by the strong UV field from the central star cluster and by a fast outflow creating a bright sho…
