Weak lensing measurements of dark matter halos of galaxies from COMBO-17

M. Kleinheinrich, P. Schneider, H. -W. Rix +8

We present a measurement of mass estimates for dark matter halos around galaxies from the COMBO-17 survey using weak gravitational lensing. COMBO-17 is particularly useful for this…

Spectral projections for the twisted Laplacian

Herbert Koch, Fulvio Ricci

The twisted Laplacian in the d=2n dimensional Euclidean space has the spectrum n+2k, k a nonnegative integer. We find sharp asymptotic bounds of the norm of the projection to the e…

The galaxy-dark matter bias in the Garching-Bonn Deep Survey

Patrick Simon, Peter Schneider, Thomas Erben +3

We measured the bias and correlation factor of galaxies with respect to the dark matter using the aperture statistics including the aperture mass from weak gravitational lensing. T…

Bottom Up Meets Heterotic Strings

Stefan Forste, Akin Wingerter

In this talk we argue that a certain class of heterotic orbifolds can be the underlying fundamental theory for recently studied field theory GUTs. In addition we demonstrate that s…

IMF variations and their implications for Supernovae numbers

C. Weidner, P. Kroupa

The stellar initial mass function (IMF) integrated over an entire galaxy is an integral over all separate star-formation events. Since most stars form in star clusters with differe…

How star clusters could survive low star formation efficiencies

M. Fellhauer, P. Kroupa

After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of high mass stars and definitely the on-set of the fir…
