Outflow forces in intermediate-mass star formation
... Results. Outflow parameters, including the forces, were derived for all sources. Temperatures in excess of 50 K were found for all flows, in line with recent low-mass results. However, comparison with other studies could ...

On the Origin of Scales and Scaling Laws in Star Formation
... It should be noted that like the model of Paper I, in this first study we in- clude no explicit feedback mechanism. Instead the model utilizes a few crude approximations to account for the qualitative effects of ...

Star formation histories of z~1 galaxies in LEGA C
... Another approach is to use photometric measurements to trace SFHs, however, individual galaxy evolution is not easily traced with this method due to high uncer- tainties. In this case, one can investigate average SFHs of ...

Galaxy Zoo: star formation versus spiral arm number
... Grand design spiral arms are typically better defined and higher contrast than many-arm structures (Elmegreen et al. 2011). We have also seen that, despite having fewer arms, they have similar total SFRs. These ...

Major mergers are not significant drivers of star formation or morphological transformation around the epoch of peak cosmic star formation
... Blue galaxies are selected using rest-frame dust-corrected U- V colours (Figure 2), which shows the expected large peak of blue galaxies and an extended distribution towards red galaxies. We de- fine the cut-off between ...
