Fermi LAT search for internal bremsstrahlung signatures from dark matter annihilation

Fermi LAT search for internal bremsstrahlung signatures from dark matter annihilation

A commonly encountered obstacle in indirect searches for galactic dark matter is how to disentangle possible signals from astrophysical backgrounds. Given that such signals are most likely subdominant, the search for pronounced spectral features plays a key role for indirect detection experiments; monochromatic gamma-ray lines or similar features related to …
