Prof. Kandaswamy Subramanian (IUCAA, Pune)
The origin and maintenance of coherent magnetic fields in galaxies is reviewed. We begin with an interesting baroclynic battery which can generate seed magnetic fields, worked out in collabration with Prof. Chitre. These seed fields need to be further amplified and maintained by a dynamo to explain observed magnetic fields in galaxies. Basic ideas behind large-scale turbulent dynamos are...
