Dissociative Recombination of Rotationally Cold OH${}^{+}$ and Its Implications for the Cosmic Ray Ionization Rate in Diffuse Clouds

Ábel Kálosi, Lisa Gamer, Manfred Grieser +12

Observations of OH${}^{+}$ are used to infer the interstellar cosmic ray ionization rate in diffuse atomic clouds, thereby constraining the propagation of cosmic rays through and the s…
