“Spectroscopic Surveys with the ELT: A Gigantic Step into the Deep Universe”
Start date: 17/10/2017
End date: 20/10/2017
Meeting place: Palacio de Congresos de Toledo
Organizer: Jesús Gallego (UCM)
The European Extremely Large Telescope (E-ELT) will be the world’s largest optical/IR facility for at least a generation. It will have an immense collecting area, equivalent to gathering together all the current large telescopes in use today. Multi-object spectroscopy will be a key capability of the observatory, immediately able to harness its unprecedented sensitivity to deliver unique surveys which address a broad range of important topics in contemporary astrophysics.
The conceptual design of MOSAIC, a powerful multi-object spectrograph for the E-ELT, will conclude in late 2017. The design combines high-multiplex near-IR and visible spectroscopy, together with AO-corrected spectroscopy in the near-IR that exploits the fantastic angular resolution of the E-ELT across a large field of view. These capabilities will enable MOSAIC to tackle fundamental questions that are simply out of reach of other facilities. In cosmology, MOSAIC will lift the veil on how matter is distributed in distant galaxy haloes, including dark matter and missing baryons. It will also result in a leap forward in our understanding of how present-day galaxies assemble. This includes detecting nearby primordial stars and the very first galaxies at the epoch of reionisation, the most exhaustive dynamical survey of distant galaxies ever undertaken and the detailed study of the stellar populations.
This colloquium is timed to discuss the scientific opportunities of surveys with MOSAIC, focussing in particular on simulated performances from the conceptual design. It will also take stock of other developments that will influence surveys envisaged for the late 2020s.
Scientific topics covered by the colloquium will include:
Probing the stellar populations at the heart of the Milky Way
Dissecting the different structural components of the Milky Way
Unravelling the stellar components of galaxies in the Local Volume
Spectroscopy of luminous stars far beyond the Local Group
Evolution/universality of the initial mass function
Properties of high-z dwarfs and their role in galaxy assembly
Constraints on the dark matter properties of high-z galaxies
Dynamical properties and formation of galaxies
Tomography of the high-redshift intergalactic medium
Evolution and baryon content of galaxy halos
Surveys of high-z AGN
Spectroscopy of first-light galaxies & the era of reionisation
This is a RIA supported workshop (AYA2015-71939-REDI): NO FEE is requested.
