Deuteration of c-CH towards the pre-stellar core L1544
K. Giers, S. Spezzano, F. Alves +7
Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…
The Dense Gas Fraction in Galactic Center Clouds
E. A. C. Mills, A. Ginsburg, K. Immer +5
We present an analysis of gas densities in the central R=300 parsecs of the Milky Way, focusing on three clouds: GCM-0.02-0.07 (the 50 km/s cloud), GCM-0.13-0.08 (the 20 km/s cloud…
Deuteration of ammonia in the starless core Ophiuchus/H-MM1
Jorma Harju, Fabien Daniel, Olli Sipilä +13
Ammonia and its deuterated isotopologues probe physical conditions in dense molecular cloud cores. With the aim of testing the current understanding of the spin-state chemistry of…
Collisional excitation of singly deuterated ammonia NHD by H
F. Daniel, A. Faure, L. Wiesenfeld +3
The availability of collisional rate coefficients with H is a pre-requisite for interpretation of observations of molecules whose energy levels are populated under non local th…
Weak maser emission of methyl formate toward Sagittarius B2(N) in the Green Bank Telescope PRIMOS Survey
Alexandre Faure, Anthony J. Remijan, Krzysztof Szalewicz +1
A non-LTE radiative transfer treatment of cis-methyl formate (HCOOCH3) rotational lines is presented for the first time using a set of theoretical collisional rate coefficients. Th…
CII in the Interstellar Medium: Excitation by H2 Revisited
Laurent Wiesenfeld, Paul F. Goldsmith
C is a critical constituent of many regions of the interstellar medium, as it can be a major reservoir of carbon and, under a wide range of conditions, the dominant gas coolant…
