DESCRIPTION:The existence and nature of Dark Matter remains one of the gre
 at open questions in astrophysics\, cosmology\, and particle physics. Alth
 ough its existence is well established through gravitational evidence\, no
  confirmed non-gravitational interaction with the Standard Model has been 
 observed. Among the most theoretically motivated candidates are Weakly Int
 eracting Massive Particles (WIMPs)\, which in many scenarios can annihilat
 e or decay into charged particles. In environments permeated by magnetic f
 ields\, these particles produce synchrotron radiation that can be detected
  at radio frequencies.\n \nMost indirect searches have concentrated on pr
 ompt gamma-ray emission. However\, radio observations offer high angular r
 esolution and detailed morphological information\, allowing a spatially re
 solved study of the emission and improving the ability to distinguish a po
 tential dark matter signal from conventional astrophysical backgrounds.\nI
 n this work\, I present recent predictions of synchrotron emission from se
 veral extragalactic targets where dark matter is expected to dominate the 
 mass distribution. Focusing exclusively on the radio band\, I discuss the 
 implications of these results for current and upcoming facilities such as 
 the Square Kilometre Array\, and evaluate their potential to constrain WIM
 P properties through radio observations alone.\n\nhttps://agenda.infn.it/e
