Stochastic gravitational wave background from cold dark matter halos
Carmelita Carbone, Carlo Baccigalupi, Sabino Matarrese
The current knowledge of cosmological structure formation suggests that Cold Dark Matter (CDM) halos possess a nonspherical density profile, implying that cosmic structures can be…
The impact of gas physics on strong cluster lensing
Ewald Puchwein, Matthias Bartelmann, Klaus Dolag +1
Previous studies of strong gravitational lensing by galaxy clusters neglected the potential impact of the intracluster gas. Here, we compare simulations of strong cluster lensing i…
Testing Dark Energy and Light Particles via Black Hole Evaporation at Colliders
Michael Doran, Joerg Jaeckel
We show that collider experiments have the potential to exclude a light scalar field as well as generic models of modified gravity as dark energy candidates. Our mechanism uses the…
Large scale inhomogeneity and local dynamical friction
A. Just, J. Penarrubia
We investigate the effect of a density gradient on Chandrasekhar's dynamical friction formula based on the method of 2-body encounters in the local approximation. We apply these ge…
Discovery of magnetic fields in hot subdwarfs
S. J. O'Toole, S. Jordan, S. Friedrich +1
We present initial results of a project to measure mean longitudinal magnetic fields in a group of sdB/OB/O stars. The project was inspired by the discovery of three super-metal-ri…
Cosmological bounds on the equation of state of dark matter
Christian M. Mueller
In this exploratory study, we investigate the bounds on the equation of state of dark matter. Modeling dark matter as a fluid component, we take into account both positive and nega…
