How do galaxies form? Where is dark matter hidden? What is the nature of dark energy? The mysteries of the universe constantly question humanity. Astrophysics unveils many of them, but many questions remain. These points are addressed in a mainstream book that was released on September 27th.
Former Ph.D. candidate at IAS, Jean-Baptiste Durrive has been selected as a Springer Thesis Award recipient for his doctoral thesis, defended the 13 October 2016. His manuscript, Baryonic Processes in the Large-Scale Structuring of the Universe, concerns two fundamental aspects of the evolution of the intergalactic gas, from the Epoch of Reionization until the present day Universe: the emergence of magnetic fields on cosmological scales, and the fragmentation of matter in the sheets and filaments of the cosmic web. His thesis has just been published in the Springer Theses collection. Congratulations Jean-Baptiste!

By combining multi-wavelength data obtained from space with Planck and WISE, and from the ground with MegaCam on the CFHT, a team of researchers has revealed the structure of the diffuse interstellar medium over several square degrees with unprecedented details. In particular, this study reveals the statistical properties of interstellar turbulence over a wide range of scales, from 0.01 to 10 pc.
