      abstract     = {PUNCH4NFDI is the consortium of particle and astroparticle
                      physics, astrophysics, and hadronic and nuclear physics in
                      the national research data infrastructure of Germany. It
                      aims at developing concepts and tools for efficient
                      management of digital research products in fundamental
                      physics and promotes the idea of FAIR data - which is to
                      make scientific data sets findable, accessible,
                      interoperable, and reusable. To better understand the
                      software usage of the astrophysics community in Germany,
                      PUNCH4NFDI developed a 9-question survey and disseminated it
                      via various distribution channels (mailing list, conference
                      flyer, personal communication) in 2022. In total, 130
                      computational astrophysicists responded to our survey. We
                      found that parallel codes (like AREPO) to simulate
                      gravitational N-body systems and magnetohydrodynamics are
                      heavily used in the German astrophysics community. However,
                      computer programs typically associated with research in
                      solar physics and numerical relativity turned out to be less
                      common among the participating astrophysicists. Regarding to
                      code development and sharing of astrophysical HPC
                      applications, the picture is divided. On the one hand, some
                      codes are developed by and limited to a single research
                      group in Germany; on the other hand, some codes are
                      maintained and used by large consortia spread around the
                      globe. In both cases, often a basic software version is open
                      access, but numerous scientists indicated the usage of
                      modified and unreleased versions. We also found that most
                      astrophysicists in Germany view re-using other researchers'
                      data sets as highly desirable. While smaller research groups
                      are in principle willing to publish and openly share their
                      simulation data, they often lack manpower to do so.},
