Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula
Léontine Ségal, Antoine Roueff, Jérôme Pety +28
Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…
A Search for 3-mm Molecular Absorption Line Transitions in the Magellanic Stream
Lucille Steffes, Daniel R. Rybarczyk, Snežana Stanimirović +14
The Magellanic Stream, a tidal tail of diffuse gas falling onto the Milky Way, formed by interactions between the Small and Large Magellanic Clouds, is primarily composed of neutra…
Quantifying the informativity of emission lines to infer physical conditions in giant molecular clouds. I. Application to model predictions
Lucas Einig, Pierre Palud, Antoine Roueff +29
Observations of ionic, atomic, or molecular lines are performed to improve our understanding of the interstellar medium (ISM). However, the potential of a line to constrain the phy…
H I Kinematics and the E(B-V)/N(H I) ratio
Harvey Liszt
The cm H I emission that is used to trace the gas to dust ratio at high Galactic latitudes has contributions from material beyond the Milky Way disk, with uncertain and likely…
Bias versus variance when fitting multi-species molecular lines with a non-LTE radiative transfer model
Antoine Roueff, Jérôme Pety, Maryvonne Gerin +28
Robust radiative transfer techniques are requisite for efficiently extracting the physical and chemical information from molecular rotational lines.We study several hypotheses that…
H2CO and CS in diffuse clouds: Excitation and abundance
Maryvonne Gerin, Harvey Liszt, Jerome Pety +1
To provide constraints on the chemical processes responsible for the observed columns of organic species, we used NOEMA to observe the sight line toward NRAO150 in the 2mm spectral…
