TOI-2155 b: A Massive Brown Dwarf or a Very Low-Mass Star?
Md Redyan Ahmed, Tansu Daylan, Theron W. Carmichael +14
We present TOI-2155\,b, a massive transiting companion, discovered using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission and confirmed with ground-based RV me…
Murriyang cryogenic phased array feed: spectral-line results and noise-reduction methods
L. Staveley-Smith, S. Barker, R. Berangi +25
Spectral-line results from a new cryogenic phased array feed (cryoPAF) on the Murriyang telescope at Parkes are presented. This array offers a significant improvement in field of v…
Tracing Gas Kinematics and Interactions between H II Regions and Molecular Clouds using VLA Observations of Recombination Lines and Hydroxyl
E. Cappellazzo, J. R. Dawson, Mark Wardle +7
Observational studies of HII region-molecular cloud interactions constrain models of feedback and quantify its impact on the surrounding environment. A recent hypothesis proposes t…
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…
