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!

Scientists using data from the GOLF instrument onboard the ESA/NASA SOHO solar observatory have found long-sought gravity modes of seismic vibration that imply the Sun's core is rotating four times faster than its surface. IAS is Principal Investigator of the GOLF instrument and has participated to this study.

PLATO - Planetary Transits and Oscillations of stars -  was adopted during a meeting of ESA’s Science Programme Committee held on June 20, 2017. This means that the mission can now move from the blueprint to construction stage. In the coming months industry will be asked to bid to supply the spacecraft platform.

For the first time, scientists have explored the magnetic field in the upper solar atmosphere by observing the polarization of ultraviolet light from the Sun. They accomplished this by analyzing data taken by the CLASP sounding rocket experiment during its 5-minute flight in space on September 3, 2015. Now that ultraviolet spectropolarimetry, the method used in the CLASP project, has been proven to work, it can be used in future investigations of the magnetic fields in the upper chromosphere and the transition region to better understand activity in the solar atmosphere.

Monday, April 10, at the headquarters of JAXA (the Japanese space agency) in Tokyo, J-Y. Le Gall, President of CNES and N. Okumura, his counterpart at JAXA, signed a scientific and technical cooperation agreement for the MMX exploration mission to Phobos and Deimos, the two moons of Mars. The primary objective of this mission, which is scheduled for launch in 2024, is to characterise the properties and composition of these two objects in order to determine whether they are derived from asteroids in the outer belt (the carriers of volatiles: water and carbon compounds), or objects re-accreted after a giant impact with Mars, as per the origin of the Earth's Moon.
