Gravitational wave induced baryon acoustic oscillations
Christian Döring, Salvador Centelles Chuliá, Manfred Lindner +2
We study the impact of gravitational waves originating from a first order phase transition on structure formation. To do so, we perform a second order perturbation analysis in the…
Intrinsic and extrinsic gravitational flexions
Eileen Sophie Giesel, Basundhara Ghosh, Bjoern Malte Schaefer
The topic of this paper is a generalisation of the linear model for intrinsic alignments of galaxies to intrinsic flexions: In this model, third moments of the brightness distribut…
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…
Symmetric gravitational closure
Maximilian Düll, Nils L. Fischer, Bjoern Malte Schaefer +1
We show how to exploit symmetry assumptions to determine the dynamical equations for the particular geometry that underpins given matter field equations. The procedure builds on th…
Formation of the First Black holes: Formation and evolution of the cosmic large-scale structure
Bjoern Malte Schaefer
The article is part of a review volume on the formation of the first black holes and summarises FLRW-cosmologies, the statistical description of cosmic structures as Gaussian rando…
Imitating intrinsic alignments: A bias to the CMB lensing-galaxy shape cross-correlation power spectrum induced by the large-scale structure bispectrum
Philipp M. Merkel, Bjoern Malte Schaefer
Cross-correlating the lensing signals of galaxies and comic microwave background (CMB) fluctuations is expected to provide valuable cosmological information. In particular it may h…
