Indirect Dark Matter Detection
- Manuela Vecchi
Galaxy clusters are the largest gravitationally bound structures in the Universe, being completely dark matter (DM) dominated objects. For DM decay, local galaxy clusters yield the highest expected fluxes respect to other prime targets. For the DM annihilation scenario, clusters can provide fluxes comparable to the ones from dwarf spheroidal galaxies, as long as the DM interactions expected in...
Dark matter (DM), a large (~85%) non-baryonic and non-relativistic component of the matter density of the Universe, likely consists of one or several so-far undetected particles hypothesized in theories beyond the Standard Model (SM). One of the most promising approaches to shed light on the nature of DM particles is to search for signatures of their annihilation or decay into SM particles...
Primordial black holes represent a natural candidate for one of the components of the dark matter in the Universe. In this talk, some of their potential signals will be examined, such as the emission of particles due to Hawking evaporation and due to the accretion of the surrounding matter. The most relevant probes capable of constraining their masses and population will be discussed.
Stellar streams whose progenitor is a dwarf galaxy (dG) are particularly interesting targets for dark matter (DM) searches, since dGs are thought to be highly DM-dominated systems. We expect these streams to have lost most of their DM content during the stretching process, yet a significant amount of DM should remain within their core. If the DM particles are Weakly Interacting Massive...
Axions and axion-like particles (ALPs) are hypothetical particles predicted by several extensions of the Standard Model and are viable candidates for solving one of the ultimate mysteries of the Universe: dark matter. By exploring the spectra of astrophysical objects obtained from observations with the Large Size Telescope (LST1), we can search for signatures that such particles may leave. In...
KM3NeT is an underwater neutrino telescope located at two sites in the Mediterranean sea. Neutrinos are indirectly detected from the products of their interactions, which produce Cherenkov radiation. The ORCA detector, off the coast of Toulon, is designed to measure atmospheric neutrino oscillations, and the ARCA detector, off the coast of Sicily, is designed to search for neutrinos from...
Intermediate Mass Black Holes (IMBHs) with a mass range between 100 $M_\odot$ and $10^6$ $M_\odot$ are expected to be surrounded by high dark matter densities, so-called dark matter spikes. The high density of self-annihilating Weakly Interacting Massive Particles (WIMPs) in these spikes leads to copious gamma-ray production. Sufficiently nearby IMBHs could therefore appear as unidentified...
