Mapping the Cosmic-Ray Ionization Rate in the Local Galaxy with H
Nick Indriolo, Alexei V. Ivlev, T. Pellegrin +6
Chemistry in diffuse molecular clouds relies primarily on rapid ion-molecule reactions. Formation of the initial ions, H and H, is dominated by cosmic-ray ionization of H…
MeerKAT observations of the spiral galaxy NGC 2997 in the S band. Detection of high dynamo modes
A. Damas-Segovia, R. Beck, S. A. Mao +18
We seek to exploit the expanded observational range of the MeerKAT radio telescope with the new S-band receivers (2.0-2.8 GHz). To showcase its enhanced capabilities, we conducted…
Faint absorption of the ground state hyperfine-splitting transitions of hydroxyl at 18 cm in the Galactic Disk
M. R. Rugel, H. Beuther, J. D. Soler +15
The interstellar hydride hydroxyl (OH) is a potential tracer of CO-dark molecular gas. We present new absorption line observations of OH at 18-cm wavelength towards four continuum…
Measuring the ISM Content of Nearby, Luminous, Type 1 and Type 2 QSOs through CO and [C II]
Yuanze Luo, A. O. Petric, R. M. J. Janssen +18
We present observations of CO(1--0) and CO(2--1) lines from the Institut de radioastronomie millimétrique (IRAM) 30m telescope toward 20 nearby, optically luminous type 2 quasars…
