Abstract
We present a search for dark matter spectral lines in the Galactic Centre (GC) region with the MAGIC telescopes. The MAGIC telescopes, located on the Canary island of La Palma (Spain), are sensitive to photons in the energy range from 50 GeV to 50 TeV with low zenith angle observations. MAGIC has performed indirect dark matter searches with various astrophysical targets. Since the MAGIC telescopes are located in the northern hemisphere, the GC is visible only at high zenith angles. Observations at high zenith angles significantly increase the telescopes’ effective collection area, which boosts sensitivity for gamma rays in the TeV regime. We report the results obtained with more than 200 hours of high zenith angle observations of the GC region with MAGIC.

Summary
We present the first search for dark matter (DM) spectral lines in the Galactic centre (GC) region with the MAGIC telescopes. The MAGIC telescopes, located on the Canary island of La Palma (Spain), are sensitive to gamma rays in the energy range from 50 GeV to 50 TeV. Observations at high zenith angles significantly increase the telescopes’. Collection area and sensitivity for gamma rays in the TeV regime. We present the results obtained with more than 200 hours of high-zenith angle observations of the GC region with MAGIC, which allow us to probe promising heavy SUSY models, and to obtain competitive limits to the DM annihilation cross-section at high DM particle mass, compared to existing constraints. We will discuss how we exploit the data from a complex sky region to search for a line-like DM signature. Tomohiro Inada,a,∗ Daniel Kerszberg,b Moritz Hütten,c Masahiro Teshima,a,c Javier
