Origin of Matter and Evolution of Galaxies

The 13th international symposium on Origin of Matter and Evolution of Galaxies (OMEG2015) will be held in Beijing, China on June 24-27, 2015. This symposium is the 13th of such series, started 1988, to exchange the progress of nuclear astrophysics and related fields. As demonstrated in previous ones, this symposium series provide good opportunity to attract researchers in fields of nuclear physics, astrophysics, and more.

IAU 311: Galaxy Masses as Constraints of Formation Models

In the era of precision cosmology, we think we can accurately predict the distribution of dark matter in the Universe. However the impact of baryonic physics is still largely unknown and our understanding of galaxy formation must rely on observations. A key advance in recent years has been the ability to enrich studies of the luminosity evolution of galaxies with determinations of their stellar or total masses from dynamical analyses using stellar populations, stellar or gaseous dynamical models, weak or strong lensing. Contrary to the light distribution alone, the distribution of both the stellar and dark matter in galaxies can be robustly compared to galaxy formation models.
