Clear evidence for the presence of large amounts of dark matter was found as early as the 1930s. To date, however, no fundamental breakthrough has been made in understanding the nature of dark matter or in identifying a specific candidate particle. Unlike visible matter, dark matter (almost) does not interact electromagnetically, which of course makes its direct detection by classical astronomical methods enormously difficult. So far, dark matter has been detected through its gravitational interaction with conventional matter.
To study it in more detail and gain new insights, the development of advanced dark matter detection capabilities is a current research topic. One such channel is indirect searches for decay or annihilation products of hypothetical dark matter particles with high-energy astroparticle physics experiments.
In Dortmund, we are trying to advance the possibilities of indirect detection methods using neutrinos in the IceCube experiment and photons with the MAGIC and CTA telescopes by theoretical preliminary work, by planning and performing measurement campaigns, and by analyzing observational data. In addition, the theoretical limits for experimental possibilities for the detection of dark matter are investigated with simulations.
- Effect of velocity modification of the dark matter profile on the capture rate in the Earth or Sun with respect to current neutrino telescopes.
- Determination of expected gamma-ray flux from dark matter annihilation for the dwarf galaxy Ursa Major II.
- Calculations of expected gamma-ray fluxes from dark matter annihilation using the example of promising dwarf galaxies in the Milky Way halo.

Location & approach
The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.
The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.
One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.
