DESCRIPTION:Speakers: DAVID ALONSO LUZQUIÑOS SAAVEDRA (Pontificia Univers
 idad Católica del Perú)\nThe microscopic nature of dark matter (DM) rema
 ins one of the major open questions in particle physics and astrophysics. 
 Weakly interacting massive particles (WIMPs) are among the most extensivel
 y studied candidates and may produce high-energy gamma rays through annihi
 lation. Intermediate-mass black holes (IMBHs) are promising targets for in
 direct searches because black hole growth within a dark matter halo can ge
 nerate steep density spikes\, enhancing the annihilation signal.\n\nWe dev
 elop a framework to estimate the sensitivity of the Southern Wide-field Ga
 mma-ray Observatory (SWGO) to gamma rays from dark matter annihilation in 
 spikes around IMBHs. The population and spatial distribution of IMBHs will
  be characterized using cosmological simulations\, including the EAGLE cat
 alog. For each scenario\, we model the dark matter density profile and com
 pute the differential gamma-ray flux as a function of the dark matter mass
 \, annihilation cross section\, and final state.\n\nThe predicted flux is 
 folded with SWGO instrumental response functions to obtain reconstructed e
 vent distributions. We present preliminary results from the implementation
  and validation of the density profiles and flux calculations\, providing 
 the basis for future sensitivity limits in the (mχ\,⟨σv⟩) parameter 
 space and comparison with existing gamma-ray searches.\n\nhttps://indico.u
