Cosmological Magnetogenesis: A gaugeinvariant approach,Used
Delivery time: 8-12 business days (International)
Astrophysical observations indicate that almost all environments in the Universe are magnetized, and the more we search for extragalactic fields, the more pervading they are revealed to be. The next logical step is to ask why these largescale magnetic fields are ubiquitous in a Universe as diverse as ours and how did these fields originate? This thesis attempts to answer this question, using secondorder gaugeinvariant perturbation theory to develop a selfconsistent framework in which the nonlinear coupling between inflationary gravitational waves and primordial largescale magnetic fields can be studied. The magneticgravito interaction is shown to produce a sufficient amplification of both a homogeneous and inhomogeneous magnetic field to within the strength limits required to support the galactic dynamo.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
