Variational Inference Using a Differentiable Multigrid Linear Solver
Andrés RamÃrez, Philipp Haim, David Föger +9
Gradient-based Bayesian inference methods require efficient access to Jacobian and adjoint-Jacobian operators of high-dimensional forward models. While multigrid solvers provide ne…
Milky Way Atlas: A radial-velocity-resolved, three-dimensional map of H I within 1.25 kpc
Lewis McCallum, Laurin Söding, Mareike Berkner +9
We present a velocity-resolved three-dimensional map of local atomic hydrogen (HI) within 1.25 kpc of the Sun, tackling the challenge of converting emission from position-position-…
Stochastic modelling of cosmic-ray sources for Galactic diffuse emissions
Anton Stall, Philipp Mertsch
Galactic diffuse emissions in gamma rays and neutrinos arise from interactions of cosmic rays with the interstellar medium and probe the cosmic-ray intensity away from the Solar sy…
Spectrum and anisotropies of Galactic cosmic rays: a laboratory for magnetic fields
Philipp Mertsch
Much has been learned about Galactic cosmic rays in the past decade: On the observational side, the spectra of cosmic ray nuclei have been directly measured with high precision, re…
Local dark matter density from Gaia DR3 K-dwarfs using Gaussian processes
Laurin Söding, Ruben L. Bartel, Philipp Mertsch
The local dark matter density provides constraints on dark matter models and is of importance for experiments hoping to detect dark matter particles in the laboratory. The advent o…
Spatially Coherent 3D Distributions of HI and CO in the Milky Way
Laurin Söding, Gordian Edenhofer, Torsten A. EnÃlin +6
The spatial distribution of the gaseous components of the Milky Way is of great importance for a number of different fields, for example, Galactic structure, star formation, and co…
