Cosmology & eXtragalactics

Welcome on the pages of the COSMology & eXtragalactics (COSM!X) team.

 

Our research reaches from the primordial fluctuations in the Universe down to its structuration at the largest scales in the most recent era. We study how the cosmic web elements are forming and evolving both through modelling and observations.

IAS has a new and exciting arrival: a new mobile dilution cryostat has been built and delivered by BlueFors Cryogenics, allowing us to measure detectors and detection chain elements at sub-Kelvin temperatures. Irradiation of highly sensitive detectors by cosmic rays is a daunting problem for many space missions, and the IAS is among the laboratories that have been investigating this problem since the launch of Planck-HFI.

With its observations in the middle-infrared range, the James Webb Space Telescope (JWST) is going to revolutionise our understanding of the Universe. After a competitive selection, its first observing targets have been unveiled. Over the hundred or so programmes proposed by researchers form all over the world, only 13 have been selected. One of them will be led by a collaboration involving IAS researchers.

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!
