Post-inflationary axion isocurvature perturbations facing CMB and large-scale structure
Martin Feix, Steffen Hagstotz, Andreas Pargner +3
Dark matter comprised of axion-like particles (ALPs) generated by the realignment mechanism in the post-inflationary scenario leads to primordial isocurvature fluctuations. The pow…
Isocurvature bounds on axion-like particle dark matter in the post-inflationary scenario
Martin Feix, Johann Frank, Andreas Pargner +3
We assume that dark matter is comprised of axion-like particles (ALPs) generated by the realignment mechanism in the post-inflationary scenario. This leads to isocurvature fluctuat…
Probing cosmic velocity-density correlations with galaxy luminosity modulations
Martin Feix
We study the possibility of using correlations between spatial modulations in the observed luminosity distribution of galaxies and the underlying density field as a cosmological pr…
Lopsidedness of self-consistent galaxies by the external field effect of clusters
Xufen Wu, Yougang Wang, Martin Feix +1
Adopting Schwarzschild's orbit-superposition technique, we construct a series of self-consistent galaxy models, embedded in the external field of galaxy clusters in the framework o…
A question of separation: disentangling tracer bias and gravitational nonlinearity with counts-in-cells statistics
Cora Uhlemann, Martin Feix, Sandrine Codis +9
Starting from a very accurate model for density-in-cells statistics of dark matter based on large deviation theory, a bias model for the tracer density in spheres is formulated. It…
Speed from light: growth rate and bulk flow at z ~ 0.1 from improved SDSS DR13 photometry
Martin Feix, Enzo Branchini, Adi Nusser
Observed galaxy luminosities (derived from redshifts) hold information on the large-scale peculiar velocity field in the form of spatially correlated scatter, which allows for boun…
