Cavendish Astrophysics


HI 21cm cosmology meeting

Cambridge, 27th June - 1st July 2016


*** The registration is now closed ***



The upcoming years will witness a revolution in HI 21cm interferometric observations of the epochs of Cosmic Dawn and Reionization. The potential is huge, as the 21cm line of neutral hydrogen probes both astrophysics and cosmology during these poorly understood epochs. First generation instruments, including LOFAR, MWA, and PAPER, are producing the first interesting limits on the reionization HI 21cm signal, with the potential for a statistical (power spectrum) detection in the next few years. Second generation instruments like HERA and SKA, are under construction, and could provide us with tomographical maps of the early Universe.

The success of these large investments will be measured by what we learn about our Universe. To tap into the available wealth of information, we need to overcome significant challenges, on both the observational and theoretical fronts. Thus far, these investigations have proceeded more-or-less independently, in small groups. However a synergy between observers and theorists could be crucial in providing realistic data analysis pipelines that couple theory to observation. These will include foreground removal, data processing, modeling the cosmic signal, statistical techniques, with each component depending in detail on the others.

The proposed workshop is intended to bring together instrumentalists, observers and theorists, in order to pool together knowledge and foster lasting collaborations. The latest results from the active experiments will be discussed, as well as the capabilities and design of the next generation facilities. This workshop will foster the establishment of HI 21cm cosmology studies in Cambridge, at a critical juncture in the design of SKA-Low – a project in which Cavendish Astrophysics plays a leading technical role. The workshop will include scientists from the global reionization efforts, including South Africa, Europe, Australia, and the USA.

The goal is to maximize the scientific return of the upcoming 21cm observations of the epochs of Reionization and Cosmic Dawn.
