Unraveling the identity of dark matter remains one of the most crucial unresolved puzzles. I am engaged in phenomenological studies, proposing attractive dark matter models and analyzing their detectability in experiments. Our previous research focused on models known as thermal dark matter, which were in equilibrium with standard model particles in the early universe, and their implications for gamma-ray emissions from the galactic center. I look forward to delving deeper into these studies and exploring new avenues within a broader context.
