The nature of dark matter is a driving question of 21st century physics. Dark matter particle interactions could imprint characteristic signals in cosmic-ray and multi-wavelength observations of the sky. The central challenge is to distinguish these signatures from similar spectra produced by standard astrophysical processes, such as the life and death of stars and the interactions of cosmic rays with interstellar material. I will review my group’s research, which spans from opening new windows onto antinuclei signatures of dark matter, as enabled by novel Si detector technology, to delivering new insights on both light dark matter and stellar backgrounds to these searches, as enabled by novel X-ray observation strategies.
