Systematic Observations of Methanol and Other Organics in Comet P/Swift-Tuttle: Discovery of New Spectral Structure at 3.42 μm
TL;DR: In this article, a detailed study of the 3.4-μm "cometary organics feature" in Comet P/Swift-Tuttle (1992 XXVIII) is presented, which reveals spectral structure in the form of a pronounced peak centered at a rest frequency of(2920.24 ± 0.09) cm-1.424 μm.

Patrick M. Motl,Jan E. Staff,Athira Menon,Falk Herwig,Wesley Even,Chris L. Fryer,Thomas R. Geballe,Marco Pignatari,Geoffrey C. Clayton,Joel E. Tohline +9 more
TL;DR: In this article, the authors investigated whether such a low ratio can be obtained in simulations of the merger of a CO and a He WD in a binary R Coronae Borealis (RCB) system.

Constraining the Environment of CH+ Formation with CH3+ Observations
TL;DR: In this paper, the formation of CH+ in the interstellar medium has been studied using CH3+ observations, and it is shown that observations of more CH 3+ transitions with higher signal-to-noise ratios are necessary to place any constraints on models where magnetic acceleration of ions drives the formation.

Three-Dimensional Observations of H_2 Emission around Sgr A East - I. Structure in the Central 10 Parsecs of Our Galaxy
Sungho Lee,Soojong Pak,Minho Choi,Christopher J. Davis,Thomas R. Geballe,Robeson M. Herrnstein,Paul T. P. Ho,Y. C. Minh,Sang-Gak Lee +8 more
TL;DR: In this paper, velocity-resolved spectra of the H_2 v=1-0 S(1) (lambda = 2.1218 micron) emission line at 2 arcsec angular resolution (or 0.08 pc spatial resolution) were obtained in four regions within the central 10 pc of the Galaxy where the supernova-like remnant Sgr A East is colliding with molecular clouds.

THE 3-5 μm SPECTRUM OF NGC 1068 AT HIGH ANGULAR RESOLUTION: DISTRIBUTION OF EMISSION AND ABSORPTION FEATURES ACROSS THE NUCLEAR CONTINUUM SOURCE
TL;DR: In this paper, the authors reported moderate resolution 3-5 mu m spectroscopy of the nucleus of NGC 1068 obtained at 0 ''.3 (20 pc) resolution with the spectrograph slit aligned approximately along the ionization cones of the active galactic nucleus.
