Description
The Fermi Large Area Telescope (LAT) has set stringent constraints on dark matter (DM) properties. We propose a comprehensive search for DM annihilation signals in highly concentrated DM regions, known as DM spikes, around intermediate-mass black holes (IMBHs). First, we investigate excess emission in dwarf active galactic nuclei (AGNs), likely hosting central IMBHs, due to classical astrophysical processes. Subsequently, we search for new physics and DM spikes within these systems. Here, we aim to enhance LAT's capabilities in indirect DM detection and advance our understanding of DM distributions around IMBHs. The results lay the groundwork for future research with next-generation observatories, including Rubin, COSI, Euclid, Roman, and LISA.
