Variational Inference Using a Differentiable Multigrid Linear Solver

Andrés Ramírez, 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…

A Three-Dimensional Tomographic Reconstruction of the Galactic Cosmic-Ray Proton Density

Hanieh Zandinejad, Jakob Roth, Vo Hong Minh Phan +7

Cosmic rays (CRs) are a ubiquitous non-thermal component of the interstellar medium (ISM). A data-driven three-dimensional (3D) map of their distribution is essential for understan…

Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies

S. Abe, J. Abhir, A. Abhishek +457

The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…

High-resolution simulations of non-thermal emission from LS 5039

Ralf Kissmann, David Huber, Philipp Gschwandtner

In a previous study, we investigated the relativistic wind dynamics in the LS 5039 system. In this work, we analyse energetic-particle transport within this modelling context, wher…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

Spatially Coherent 3D Distributions of HI and CO in the Milky Way

Laurin Söding, Gordian Edenhofer, Torsten A. Enßlin +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…
