A Novel Estimator for the Equation of State of the IGM by Ly Forest Tomography
Hendrik Müller, Christoph Behrens, David James Edward Marsh
We present a novel procedure to estimate the Equation of State of the intergalactic medium in the quasi-linear regime of structure formation based on Ly forest tomography and ap…
AxioNyx: Simulating Mixed Fuzzy and Cold Dark Matter
Bodo Schwabe, Mateja Gosenca, Christoph Behrens +2
The distinctive effects of fuzzy dark matter are most visible at non-linear galactic scales. We present the first simulations of mixed fuzzy and cold dark matter, obtained with an…
An Optimized Ly Forest Inversion Tool Based on a Quantitative Comparison of Existing Reconstruction Methods
Hendrik Müller, Christoph Behrens, David James Edward Marsh
We present a same-level comparison of the most prominent inversion methods for the reconstruction of the matter density field in the quasi-linear regime from the Ly forest flux.…
Axion Miniclusters Made Easy
David Ellis, David J. E. Marsh, Christoph Behrens
We use a modified version of the Peak Patch excursion set formalism to compute the mass and size distribution of QCD axion miniclusters from a fully non-Gaussian initial density fi…
Radiative Transfer Distortions of Lyman- Emitters: a New Fingers-of-God Damping in the Clustering in Redshift Space
Chris Byrohl, Shun Saito, Christoph Behrens
Complex radiative transfer (RT) of the Lyman- photons poses a theoretical challenge to galaxy surveys which infer the large-scale structure with Lyman- emitters (LAEs). Guide…
Substructure of fuzzy dark matter haloes
Xiaolong Du, Christoph Behrens, Jens C. Niemeyer
We derive the halo mass function (HMF) for fuzzy dark matter (FDM) by solving the excursion set problem explicitly with a mass-dependent barrier function, which has not been done b…
Effects of Lyman alpha scattering in the IGM on clustering statistics of Lyman alpha emitters
Christoph Behrens, Jens Niemeyer
We investigate the correlations between the observed fraction of Lyman alpha emission from star-forming galaxies and the large scale structure by post-processing snapshots of a lar…
