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…

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…
Exploring non-thermal emission from the star-forming region NGC 3603 through a realistic modelling of its environment
Manuel Rocamora, Anita Reimer, Guillem Martí-Devesa +1
Context. Star-forming regions are gaining considerable interest in the high-energy astrophysics community as possible Galactic particle accelerators. In general, the role of electr…
The influence of the 3D Galactic gas structure on cosmic-ray transport and -ray emission
Andrés Ramírez, Gordian Edenhofer, Torsten A. Enßlin +6
Cosmic rays (CRs) play a major role in the dynamics of the interstellar medium (ISM). Their interactions and transport ionize, heat, and push the ISM thereby coupling different reg…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
Prospects for a survey of the Galactic plane with the Cherenkov Telescope Array
CTA Consortium
Approximately one hundred sources of very-high-energy (VHE) gamma rays are known in the Milky Way. A survey of the entire Galactic Plane in the energy range from a few tens of GeV…
Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…
Efficient numerical methods for Anisotropic Diffusion of Galactic Cosmic Rays
Pranab J. Deka, Ralf Kissmann, Lukas Einkemmer
Anisotropic diffusion is imperative in understanding cosmic ray diffusion across the Galaxy, the heliosphere, and the interplay of cosmic rays with the Galactic magnetic field. Thi…
