On the Diversity of M-Star Astrospheres and the Role of Galactic Cosmic Rays Within
Konstantin Herbst, Klaus Scherer, Stefan E. S. Ferreira +7
With upcoming missions such as the James Webb Space Telescope (JWST), the European Extremely Large Telescope (ELT), and the Atmospheric Remote-sensing Infrared Exoplanet Large-surv…
Viability tests of \textit{f(R)}-gravity models with Supernovae Type 1A data
Renier Hough, Amare Abebe, Stefan Ferreira
In this work, we will be testing four different general \textit{f(R)}-gravity models, two of which are the more realistic models (namely the Starobinsky and the Hu-Sawicki models),…
Cosmic rays in astrospheres
Klaus Scherer, Ausgusts van der Schyff, Dominik Bomans +7
Cosmic rays passing through large astrospheres can be efficiently cooled inside these "cavities" in the interstellar medium. Moreover, the energy spectra of these energetic particl…
Unidentified Gamma-Ray Sources as Ancient Pulsar Wind Nebulae
O. C. de Jager, S. E. S. Ferreira, A. Djannati-Ataï +6
In this paper we explore the evolution of a PWN while the pulsar is spinning down. An MHD approach is used to simulate the evolution of a composite remnant. Particular attention is…
