Description

I will present several new methods that we currently employ to make progress in indirect dark matter searches. (1) A wavelet fluctuation analysis of gamma-ray data from the inner Galaxy. Using this method we find strong support for the millisecond pulsar (MSP) hypothesis of the Fermi GeV excess in the Galactic bulge. I will discuss ongoing efforts and plans to search for new pulsar populations with VLA, GBT and MeerKAT. (2) A new approach to model the Galactic diffuse gamma-ray emission with SkyFACT (Sky Factorization with Adaptive Constrained Templates). This new tool allows a rapid fit with hundred thousand of parameters, which are required to adequately describe the gamma-ray data down to the shot noise level. I will show preliminary results on the GeV excess and low-latitude emission of the Fermi bubbles. (3) Differential Fisher Information. I will discuss an agnostic top-down approach to strategy development in indirect dark matter searches, based on a full-sky Fisher forecast.
