Dark Matter Annihilation in NGC 1068 — •Alexandra Scholz and Li Ruohan — TU München

If Dark Matter (DM) is of particle nature, the Weakly Interacting Massive Particle (WIMP), with an expected mass in the range of some GeV to TeV, detectable by the IceCube telescope, would be a possible candidate. For the barred spiral galaxy NGC 1068 we calculated the neutrino flux from the spike of the super massive black hole (SMBH), and the disk, induced from DM self-annihilation into Standard Model (SM) particles. The calculation was performed for the DM masses 100 GeV, 1 TeV, and 10 TeV, and different Navarro-Frenk-White (NFW) density profile parameters. The annihilation branch ratios and neutrino energy spectra were simulated with the softwares Pythia and MadDM. Comparing IceCube data from NGC 1068 with the results for those three masses, the TeV Dark Matter annihilation scenario has no conflict with the spectrum shape from NGC 1068. Therefore, DM can be a potential explanation for the neutrino flux from NGC 1068.
