Initial mass function effects on the colour evolution of disk galaxies

P. Westera, M. Samland, S. J. Kautsch +2

In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot b…

Sub-Galactic Clumps at High Redshift: A Fragmentation Origin?

Andreas Immeli, Markus Samland, Pieter Westera +1

We investigate the origin of the clumpy structures observed at high redshift, like the chain galaxies. We use a three dimensional chemodynamical simulation describing the dynamics…

Gas Physics, Disk Fragmentation, and Bulge Formation in Young Galaxies

Andreas Immeli, Markus Samland, Ortwin Gerhard +1

We investigate the evolution of star-forming gas-rich disks, using a 3D chemodynamical model including a dark halo, stars, and a two-phase interstellar medium with feedback process…

Neutron star mergers versus core-collapse supernovae as dominant r-process sites in the early Galaxy

D. Argast, M. Samland, F. -K. Thielemann +1

The astrophysical nature of r-process sites is a long standing mystery and many probable sources have been suggested in the past, among them lower-mass core-collapse supernovae (in…

The Formation of a Disk Galaxy within a Growing Dark Halo

Markus Samland, Ortwin Gerhard

We present a dynamical model for the formation and evolution of a massive disk galaxy, within a growing dark halo whose mass evolves according to cosmological simulations of struct…

Implications of O and Mg abundances in metal-poor halo stars for stellar iron yields

D. Argast, M. Samland, F. -K. Thielemann +1

Inhomogeneous chemical evolution models of galaxies which try to reproduce the scatter seen in element-to-iron ratios of metal-poor halo stars are heavily dependent on theoretical…
