Possibility of observing dark matter via the gyromagnetic Faraday effect.
نویسنده
چکیده
If dark matter consists of cold, neutral particles with a nonzero magnetic moment, then, in the presence of an external magnetic field, a measurable gyromagnetic Faraday effect becomes possible. This enables direct constraints on the nature and distribution of such dark matter through detailed measurements of the polarization and temperature of the cosmic-microwave background radiation.

Have mirror micrometeorites been detected ?
Slow-moving (v ∼ 15 km/s) ‘dark matter particles’ have allegedly been discovered in a recent experiment. We explore the possibility that these slow moving dark matter particles are small mirror matter dust particles originating from our solar system. Ways of further testing our hypothesis, including the possibility of observing these dust particles in cryogenic detectors such as NAUTILUS, are a...
متن کاملRadio emission from dark matter annihilation in the Large Magellanic Cloud
The Large Magellanic Cloud (LMC), at only 50 kpc away from us and known to be dark matter dominated, is clearly an interesting place where to search for dark matter annihilation signals. In this paper, we estimate the synchrotron emission due to weakly interacting massive particle (WIMP) annihilation in the halo of the LMC at two radio frequencies, 1.4 and 4.8 GHz, and compare it to the observe...

متن کاملMonte Carlo Studies of Transverse Faraday Rotation Profiles
Faraday Rotation measurements are a very important tool for investigating the magnetic (B) fields associated with the relativistic jets of Active Galactic Nuclei (AGN); for example, a toroidal or helical B field component should give rise to a systematic gradient in the observed Faraday rotation across the jet. However, real observed radio images have finite resolution. Typical beam sizes for c...
متن کاملFaraday Rotation Effect of Intracluster Magnetic Field on Cosmic Microwave Background Polarization
The observed magnetic field of microgauss strength in clusters of galaxies should induce the Faraday rotation effect on the linearly polarized cosmic microwave background (CMB) radiation when the CMB radiation propagates through a cluster at low redshift. The Faraday rotation arises from combined contributions of the magnetic field strength, the electron density, the cluster size, and the chara...
