Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
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…
The Influence of Streaming Velocities on the Formation of the First Stars
Anna T. P. Schauer, Simon C. O. Glover, Ralf S. Klessen +1
How, when and where the first stars formed are fundamental questions regarding the epoch of Cosmic Dawn. A second order effect in the fluid equations was recently found to make a s…
A SOFIA Survey of [CII] in the galaxy M51 I. [CII] as a tracer of Star Formation
Jorge L. Pineda, Christian Fischer, Maria Kapala +12
We present a [CII] 158um map of the entire M51 (including M51b) grand--design spiral galaxy observed with the FIFI-LS instrument on SOFIA. We compare the [CII] emission with the to…
TOPoS V: Abundance ratios in a sample of very metal-poor turn-off stars
P. François, E. Caffau, P. Bonifacio +12
Extremely metal-poor stars are keys to understand the early evolution of our Galaxy. The ESO large programme TOPoS has been tailored to analyse a new set of metal-poor turn-off sta…
WARPFIELD 2.0: Feedback-regulated minimum star formation efficiencies of giant molecular clouds
Daniel Rahner, Eric W. Pellegrini, Simon C. O. Glover +1
Star formation is an inefficient process and in general only a small fraction of the gas in a giant molecular cloud (GMC) is turned into stars. This is partly due to the negative e…
