Titre |
Searching for dark matter in extragalactic objects using radio observations |
|
Résumé |
Dark matter remains one of the central open questions in astrophysics. Among the
most motivated candidates are Weakly Interacting Massive Particles (WIMPs), which
in many scenarios can annihilate into charged particles. In environments where
magnetic fields are present, these particles produce synchrotron radiation
detectable at radio frequencies.
Radio observations offer high angular resolution and detailed morphological
information, allowing a spatially resolved study of the emission and improving our
ability to distinguish a potential dark matter signal from conventional
astrophysical backgrounds.
In this work, I will present recent predictions of synchrotron emission from
extragalactic targets where dark matter dominates the mass distribution. This
includes our recent determination of the cosmic-ray diffusion coefficient in the
LMC and our study using both total and polarized synchrotron emission outside the
Milky-Way. I will also briefly discuss our latest results on cosmic filaments,
where conventional astrophysical sources struggle to explain the observed
brightness temperature.
