Supersymmetric geometries of IIA supergravity III
Ulf Gran, George Papadopoulos, Christian von Schultz
We find that (massive) IIA backgrounds that admit a invariant Killing spinor must exhibit a null Killing vector field which leaves the Killing spinor inva…
Supersymmetric geometries of IIA supergravity II
Ulf Gran, George Papadopoulos, Christian von Schultz
We solve the Killing spinor equations of standard and massive IIA supergravities for a Killing spinor whose isotropy subgroup in Spin(9, 1) is SU(4) and identify the geometry of th…
Supersymmetric geometries of IIA supergravity I
Ulf Gran, George Papadopoulos, Christian von Schultz
IIA supergravity backgrounds preserving one supersymmetry locally admit four types of Killing spinors distinguished by the orbits of on the space of spinors. We solve t…
The High- Universe Confronts Warm Dark Matter: Galaxy Counts, Reionization and the Nature of Dark Matter
Christian Schultz, Jose Oñorbe, Kevork N. Abazajian +1
We use -body simulations to show that high-redshift galaxy counts provide an interesting constraint on the nature of dark matter, specifically Warm Dark Matter (WDM), owing to t…
Neutrinos in Non-linear Structure Formation - a Simple SPH Approach
Steen Hannestad, Troels Haugbølle, Christian Schultz
We present a novel method for implementing massive neutrinos in N-body simulations. Instead of sampling the neutrino velocity distribution by individual point particles we take neu…
