Feedback in W49A diagnosed with radio recombination lines and models
M. R. Rugel, D. Rahner, H. Beuther +20
We present images of radio recombination lines (RRLs) at wavelengths around 17 cm from the star-forming region W49A to determine the kinematics of ionized gas in the THOR survey (T…
SEDIGISM: The kinematics of ATLASGAL filaments
M. Mattern, J. Kauffmann, T. Csengeri +13
Analysing the kinematics of filamentary molecular clouds is a crucial step towards understanding their role in the star formation process. Therefore, we study the kinematics of 283…
OH absorption in the first quadrant of the Milky Way as seen by THOR
M. R. Rugel, H. Beuther, S. Bihr +20
The hydroxyl radical (OH) is present in the diffuse molecular and partially atomic phases of the interstellar medium (ISM), but its abundance relative to hydrogen is not clear. We…
ALMA survey of massive cluster progenitors from ATLASGAL. Limited fragmentation at the early evolutionary stage of massive clumps
T. Csengeri, S. Bontemps, F. Wyrowski +18
The early evolution of massive cluster progenitors is poorly understood. We investigate the fragmentation properties from 0.3 pc to 0.06 pc scales of a homogenous sample of infrare…
Mass estimates for very cold (< 8 K) gas in molecular cloud cores
Juergen Steinacker, Hendrik Linz, Henrik Beuther +2
The mass of prestellar cores is an essential ingredient to understand the onset of star formation in the core. The low level of emission from cold dust may keep parts of it hidden…
Continuum sources from the THOR survey between 1 and 2 GHz
S. Bihr, K. G. Johnston, H. Beuther +19
We carried out a large program with the Karl G. Jansky Very Large Array (VLA): "THOR: The HI, OH, Recombination line survey of the Milky Way". We observed a significant portion of…
