Flaring of Blazars from an Analytical, Time-dependent Model for Combined Synchrotron and Synchrotron Self-Compton Radiative Losses of Multiple Ultrarelativistic Electron Populations
Christian Röken, Florian Schuppan, Katharina Proksch +1
We present a fully analytical, time-dependent leptonic one-zone model that describes a simplified radiation process of multiple interacting ultrarelativistic electron populations,…
Galactic Propagation of Cosmic Rays from Individual Supernova Remnants
Nils Nierstenhoefer, Philipp Graeser, Florian Schuppan +1
It is widely believed that supernova remnants are the best candidate sources for the observed cosmic ray flux up to the knee, i.e. up to ~PeV energies. Indeed, the gamma-ray spectr…
Ionisation as indicator for cosmic ray acceleration
Florian Schuppan, Christian Röken, Natalie Fedrau +1
Astrospheres and wind bubbles of massive stars are believed to be sources of cosmic rays with energies TeV. These particles are not directly detectable, but their im…
Theoretical study of ionization profiles of molecular clouds near supernova remnants: Tracing the hadronic origin of GeV gamma radiation
Florian Schuppan, Christian Röken, Julia Becker Tjus
Context: Since a few years, signatures of supernova remnants associated with molecular clouds have been detected in gamma rays. Whether these gamma rays are generated by cosmic ray…
Cosmic-ray-induced ionization in molecular clouds adjacent to supernova remnants
F. Schuppan, J. Becker Tjus, J. H. Black +2
Energetic gamma rays (GeV to TeV photon energy) have been detected toward several supernova remnants (SNR) that are associated with molecular clouds. If the gamma rays are produced…
A possible GeV-radio correlation for starburst galaxies
S. Schöneberg, J. Becker Tjus, F. Schuppan
For star-forming regions, there is a correlation of radio and FIR-emission established. The radio emission is caused by synchrotron radiation of electrons, while the FIR emission i…
Cosmic-ray-induced ionization in molecular clouds adjacent to supernova remnants - Tracing the hadronic origin of GeV gamma radiation
F. Schuppan, J. K. Becker, J. H. Black +1
Energetic gamma rays (GeV to TeV photon energy) have been detected toward several supernova remnants (SNR) associated with molecular clouds. If the gamma rays are produced mainly b…
A multifrequency view of starburst galaxies
J. K. Becker, F. Schuppan, S. Schoeneberg
During the past few years, first observations of starburst galaxies at >GeV energies could be made with the Fermi Gamma-ray Space Telescope (GeV range) and Imaging Air Cherenkov Te…
Tracing the sources of cosmic rays with molecular ions
J. K. Becker, J. H. Black, M. Safarzadeh +1
The rate of ionization by cosmic rays in interstellar gas directly associated with gamma-ray emitting supernova remnants is for the first time calculated to be several orders of ma…
