Our universe is magnetized and its constituents are the electrons, anti-electrons (positrons), ions and dust particles. Our objective here is to discuss the formation of large scale plasma structures based on a model associated with the Jeans instability in a self-gravitating multi-component fully ionized magnetoplasma. Assuming that the plasma particles are magnetized and charged dust grains f...

The concept of quasiseparatrix layers (QSLs) has emerged as a powerful tool to study the connectivity of magnetic field lines undergoing magnetic reconnection in solar flares. Although they have been used principally by the solar physics community until now, QSLs can be employed to shed light on all processes in which reconnection occurs. We present the first application of this theory to an ex...
