Self-generated ultraviolet radiation in molecular shock waves II. CH+ and the interpretation of emission from shock ensembles
Andrew Lehmann, Benjamin Godard, Gillaume Pineau des Forêts +2
Shocks, modelled over a broad range of parameters, are used to construct a new tool to deduce the mechanical energy and physical conditions from observed atomic or molecular emissi…
Modeling accretion shocks at the disk-envelope interface -- Sulfur chemistry
M. L. van Gelder, B. Tabone, E. F. van Dishoeck +1
As material from an infalling protostellar envelope hits the forming disk, an accretion shock may develop which could (partially) alter the envelope material entering the disk. Obs…
Anomalous intensities in the infrared emission of CH explained by quantum nuclear motion and electric dipole calculations
P. Bryan Changala, David A. Neufeld, Benjamin Godard
The unusual infrared emission patterns of CH, recently detected in the planetary nebula NGC 7027, are examined theoretically with high-accuracy rovibrational wavefunctions and…
Observations and analysis of CH vibrational emissions from the young, carbon-rich planetary nebula NGC 7027: a textbook example of chemical pumping
David A. Neufeld, Benjamin Godard, P. Bryan Changala +5
We discuss the detection of 14 rovibrational lines of CH, obtained with the iSHELL spectrograph on NASA's Infrared Telescope Facility (IRTF) on Maunakea. Our observations in th…
Where infall meets outflows: turbulent dissipation probed by CH and Ly in the starburst/AGN galaxy group SMM J023990136 at z2.8
A. Vidal-García, E. Falgarone, F. Arrigoni Battaia +8
We present a comparative analysis of the (1-0) and lines, observed with the Atacama Large Millimeter Array (ALMA) and Keck telescope respectively, in the field…
