Coherent structures in the distribution of the Faraday rotation measure of extragalac-tic radio sources are isolated using wavelet transformation technique. A new algorithm of wavelet analysis for data points nonuniformly distributed on a sphere is developed and implemented. Signatures of the magnetic fields in the local (Orion) spiral arm, the Sagittarius and Carina arms, the synchrotron Loop ...

We present Very Large Array observations of twelve bona-fide and candidate brown dwarfs in the Solar neighborhood. The observed sources were chosen to cover a wide range of physical characteristics — spectral type, rotation, age, binarity, and X-ray and Hα activity — to determine the role of these properties in the production of radio activity, and hence magnetic fields. Three of the twelve sou...

the present paper is concerned with  the investigation of disturbances in a homogeneous  transversely isotropic thermoelastic rotating  medium with two temperatures, in the presence of the combined effects of   hall currents and magnetic field due to thermomechanical sources. the formulation is applied to the thermoelasticity theories developed by green-naghdi theories of type-ii and type-iii. ...
