Saito, M.A. Sánchez-Conde, M. Wilkinson, M. Wood, G. Zaharijas, H.-S. Zechlin

7 IACTs vs Fermi LAT IACTs have a large irreducible cosmic-ray background whereas the LAT can reject charged CRs at high efficiency this is a major challenge for searches for extended signals, such as dark matter annihilation in the Inner Galaxy 7

16 Spectral information using full spectral information in analysis improves sensitivity at moderate/high dark matter masses (now included in recent CTA projections shown here) h vi Galactic halo, 500h, NFW profile b b + µ + µ m Pierre, JG, & Scott,
17 Morphological information Galactic halo, 100h, comparison of analyses using full morphological information (as opposed to simple ON-OFF techniques) in analysis improves sensitivity (under study for implementation in future CTA analyses) Self-annihilation cross-section h vi [cm 3 s 1 ] % 1% 0.3% CTA Ring method CTA Morph. analysis CTA Morph. analysis (3% syst.)

18 Summary CTA will improve dramatically on existing sensitivity to DM annihilation for a range of interesting DM masses for many annihilation channels CTA will test the canonical thermal relic annihilation cross section if the Galactic halo density profile is NFW/Einasto while less promising, the LMC and Milky Way satellite galaxies are complementary targets with different uncertainties understanding and controlling systematics will be key for interpreting a possible detection or placing constraints using any targets 16
