Two new avenues in dark matter indirect detection
Ranjan Laha (Stanford/SLAC)

Indirect detection is one of the major ways to search for dark matter.
In this talk, I will introduce two new techniques. Firstly, I will show how telescopes with ~ 0.1% energy resolution can exploit the Doppler shift of sharp photon features arising from dark matter interactions and separate the signal from background. Although the technique is general, I will give an example of this search strategy with the 3.5 keV line. In the second half of my talk, I will show how limits from the searches for very high energy photons can be used to constrain dark matter interactions. As an example, I will compare these limits with the dark matter interpretation of the "IceCube excess neutrinos".
