Indirect searches for dark matter: gamma rays and neutrinos

by Tarak Nath Maity (Indian Institute of Science)



Gamma rays and neutrinos being charge-neutral are useful messengers in search for dark matter. In this talk, we will explore the prospect of recently discovered sub-PeV diffuse gamma rays by Tibet AS gamma in search of decaying dark matter. While for indirect search through neutrinos we focus on neutrinos produced from captured dark matter annihilation in a galactic distribution of neutron stars. We will see that both of these scenarios may probe unexplored regions of the parameter space for heavy dark matter.
