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…
Velocity dispersion in the interstellar medium of early galaxies
M. Kohandel, A. Pallottini, A. Ferrara +5
We study the structure of spatially resolved, line-of-sight velocity dispersion for galaxies in the Epoch of Reionization (EoR) traced by [CII] line emission. Our labo…
Early galaxy growth: mergers or gravitational instability?
A. Zanella, A. Pallottini, A. Ferrara +4
We investigate the spatially-resolved morphology of galaxies in the early Universe. We consider a typical redshift z = 6 Lyman Break galaxy, "Althaea" from the SERRA hydrodynamical…
The physical origins and dominant emission mechanisms of Lyman-alpha halos: results from the TNG50 simulation in comparison to MUSE observations
Chris Byrohl, Dylan Nelson, Christoph Behrens +6
Extended Lyman-alpha emission is now commonly detected around high redshift galaxies through stacking and even on individual basis. Despite recent observational advances, the physi…
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…
Clocking Auger Electrons
D. C. Haynes, M. Wurzer, A. Schletter +34
Intense X-ray free-electron lasers (XFELs) can rapidly excite matter, leaving it in inherently unstable states that decay on femtosecond timescales. As the relaxation occurs primar…
A random-walk model for dark matter halo spins
Andrew Benson, Christoph Behrens, Yu Lu
We extend the random-walk model of Vitvitska et al. for predicting the spins of dark matter halos from their merger histories. Using updated merger rates, orbital parameter distrib…
