The first three-dimensional map of thermal phases in the local interstellar medium

Jonathan Shelest, Shmuel Bialy, Troy A. Porter +3

The thermal state of interstellar gas controls whether it remains warm and diffuse or cools into dense clouds. Twenty-one centimetre observations have established a statistical pic…

HyGAL: Characterizing the Galactic ISM with observations of hydrides and other small molecules. III. The absorption lines of [O I], CH, and OH

W. -J. Kim, A. M. Jacob, D. A. Neufeld +17

The HyGAL Stratospheric Observatory for Infrared Astronomy (SOFIA) legacy program aims at characterizing the interstellar medium in the Milky Way using hydrides, [C II], and [O I]…

SOFIA FEEDBACK Survey: The Eagle Nebula in [C II] and Molecular Lines

Ramsey L. Karim, Marc W. Pound, Alexander G. G. M. Tielens +15

We characterize the physical conditions and energy budget of the M16 H II region using SOFIA FEEDBACK observations of the [C II] 158 m line. The O stars in the $\sim 10^{4}~{\rm…

The densities in diffuse and translucent molecular clouds: estimates from observations of C and from 3-dimensional extinction maps

David A. Neufeld, Daniel E. Welty, Alexei V. Ivlev +7

Newly-computed collisional rate coefficients for the excitation of C in collisions with H, presented recently by Najar and Kalugina (2020), are significantly larger than th…

Dissociative recombination of rotationally cold ArH

Ábel Kálosi, Manfred Grieser, Leonard W. Isberner +11

We have experimentally studied dissociative recombination (DR) of electronically and vibrationally relaxed ArH in its lowest rotational levels, using an electron--ion merged-be…

Modeling Ionized Gas in the Small Magellanic Cloud: The Wolf-Rayet Nebula N76

Elizabeth Tarantino, Alberto D. Bolatto, Rémy Indebetouw +5

We present Cloudy modeling of infrared emission lines in the Wolf-Rayet (WR) nebula N76 caused by one of the most luminous and hottest WR stars in the low metallicity Small Magella…
